These functions perform specific operations on financial periods, and return the result. You can use these to select, process, and calculate financial periods in imports, reports, or models.

All PERIOD functions are unique to XLReporting, creating functionality that does not exist in Excel.

✭ Tips:

- These functions require that you use a
**YYYY-MM**convention for the naming of periods (e.g. 2019-02). You can use PERIODNAME to give them a friendly name in reports, but internally (in data sets) the periods must follow the YYYY-MM convention. - These functions fully support fiscal years that deviate from calendar years. You can set an optional parameter in SELECTPERIOD that indicates the fiscal start month (1-12) within the calendar year. All other PERIOD functions will respond accordingly.
- Valid periods can be between 00 and 15. This enables you to use a special period for opening balances and year-end closing, as well as support fiscal years with bespoke number of periods (such as 4-4-5 periods).
- Whilst periods are processed in the YYYY-MM notation, each user can individually decide how periods are displayed in reports and models, by selecting the desired period format in Manage - Profile.

Adds the given *number* of periods to a given period. If the number is negative, it
will be substracted from the given period.

By default, this function assumes there are maximum 12 periods in a year (effectively calendar
months within a year). You can specify the optional *max* parameter if you want the
function to calculate with a different number of periods per year.

ADDPERIOD(data, number, max)

Example:

data = "2019-01"

ADDPERIOD(data, 2) = "2019-03"

Returns a period relative to the period selected by the user in response to a SELECTPERIOD function, or relative to today's date.

GETPERIOD(type)

type:

"PER" = this period (default)

"PREV" = previous
period

"NEXT" = next period

"LY.PER" = this period last year

"LY.PREV"
= previous period last year

"LY.NEXT" = next period last year

"NOW.PER" =
today's period

"NOW.PREV" = previous period to today

"NOW.NEXT" = next period to
today

"NOW.PREV.dd" = previous period to today, up until the given day

"NOW.NEXT.dd"
= next period to today, beyond the given day

Examples:

GETPERIOD() returns the period selected by the user.

GETPERIOD("PREV")
returns the previous period based on the selection by the user.

GETPERIOD("NOW.PER")
returns the period based on today's date.

GETPERIOD("NOW.PREV") returns the previous period
based on today's date.

GETPERIOD("NOW.PREV.10") returns the previous period based on today's
date up until the 10th day of this month. Beyond the 10th day, it will return the current
period.

Converts the given date to a period name (YYYY-MM) using calendar months.

In most cases, XLReporting automatically recognizes the used date format and converts
text strings to dates. In some cases, if the date format is not correctly
interpreted, you can set the *type* parameter to specify the date format.

PERIOD(data, type)

type:

"DMY" = day-month-year

"MDY" = month-day-year

"YMD"
= year-month-day

"MMY" = month as a word (e.g. Feb 2019)

Example:

data = "3-1-2019"

PERIOD(data, "DMY") = 2019-01

Converts the given date to a period name (YYYY-MM) using a week-based accounting calendar.

XLReporting will calculate the period number by comparing the given *date* to the given
*start* date of a financial year, applying the given *type* of week calendar. The
function allows the start of financial years that fall a couple of days before or after January
1st.

Alternatively, if you pass a period name, the function will convert this to a text string with the start date and end date (YYYY-MM-DD) of that given period, separated by a comma. If you want to split the dates, you can use the SPLIT function, or use the SUBSTITUTE function to replace the comma with another delimiter (e.g. in import connectors).

PERIOD(data, start, type)

type:

"445" = 4-4-5 periods (default)

"454" = 4-5-4 periods

"544" -
5-4-4 periods

Examples:

data = "2019-01-29"

PERIOD445(data, "2019-01-01") =
2019-02

PERIOD445(data, "2018-12-31", "454") = 2019-02

PERIOD445("2019-01",
"2019-01-01") = 2019-01-01,2019-01-28

PERIOD445("2019-01", "2018-12-31") =
2018-12-31,2019-01-27

Returns a friendly name for the given period.

If you set a fiscal year via the SELECTPERIOD function, the fiscal year can be included in the period name.

You can also set the starting period of a fiscal year as the *type* parameter to combine
both years in the period name.

By default, this function assumes there are maximum 12 periods in a year (effectively calendar
months within a year). You can specify the optional *max* parameter if you want the
function to calculate with a different number of periods per year.

PERIODNAME(data, type, max)

type:

"Y" = fiscal year (default)

"Q" = fiscal quarter (YYYY QQ)

"P"
= fiscal period (YYYY PP)

"U" = formatted period as per user profile setting

"W" = week
number (YYYY WW)

"I" = week number (YYYY WW) as per ISO 8601

"M" = month name (MMM
YYYY)

"L" = long month name (MMMMMM YYYY)

"C" = calendar month (without year)

"N" =
period number (without year)

2-15 = fiscal year start

Examples:

data = "2019-08"

PERIODNAME(data, "Y") = "2019"

PERIODNAME(data,
"Q") = "2019 Q3"

PERIODNAME(data, "M") = "Aug 2019"

PERIODNAME(data, 6) = "2019/20"

Returns an array of period names starting at the given *period* for the given
*number* of periods. The returned data has the same structure as a cell range or data
array, which enables you to pass this data directly into a dropdown editor or other functions
that expect a cell range or data array. You can optionally pass an *interval* (default is
1).

If you provide the optional *period* parameter, the function will check if that given
period falls within the range of periods, and return either that period (if it exists) or an
empty value (if it does not exist).

By default, this function assumes there are maximum 12 periods in a year (effectively calendar
months within a year). You can specify the optional *max* parameter if you want the
function to calculate with a different number of periods per year.

You can use the returned value by itself or as a condition inside an IF formula.

PERIODRANGE(data, number, interval, period, max)

Examples:

PERIODRANGE("2019-01", 3) = "2019-01", "2019-02",
"2019-03"

PERIODRANGE("2019-01", 3, 12) = "2019-01", "2020-01", "2021-01"

PERIODRANGE("2019-01",
3, 12, "2020-01") = "2020-01"

Calculates the number of periods between the 2 given periods. You can either pass dates, periods (YYYY-MM), or years (YYYY) as parameters.

*max* parameter if you want the
function to calculate with a different number of periods per year.

PERIODS(data, period, max)

Example:

data = "2019-01"

PERIODS(data, "2019-03") = 2

Returns the total sum of amounts based on the given period *type* and the selected
period.

This function requires that you also use a **SELECTPERIOD**
function in a filter to allow the user to select a period. Both functions work together in
selecting and calculating the appropriate period amounts based on the selected period.

If
you use this function in a **Report**, the *data*
parameter references the field for which you want the sum for the given period. If
you use this function in a **Model**, the *data* parameter needs to
reference a cell range or data array of multiple rows and 2 columns, of which the
1st column needs to contain the period, and the 2nd column needs to contain the
amounts of which you want the sum for the given period.

If you set a fiscal
year via the SELECTPERIOD function, the period sums will be adjusted accordingly.

Optionally,
you can also provide a logical *condition*, in which case amounts are only counted if the
condition is met.

PERIODSUM(data, type, condition)

type:

"PER" = this period (default)

"PREV" = previous period

"NEXT" = next period

"YTD" = year-to-date

"FY" = full year

"OPEN" = opening balance this year (= closing balance of preceding year)

"MOV" = movement this period

"MOVP" = movement previous period

"TOGO" = year-to-go

"LY.PER" = this period last year

"LY.PREV" = previous period last year

"LY.NEXT" = next period last year

"LY.YTD" = last year to date

"LY.FY" = full last year

"LY.OPEN" = opening balance last year (= closing balance of preceding year)

"LY.MOV" = movement this period last year

"LY.MOVP" = movement previous period last year

"LY.TOGO" = last year-to-go

"PTD" = period-to-date (you must select a full date in SELECTPERIOD)

"LY.PTD" = period-to-date last year (you must select a full date in SELECTPERIOD)

"FR.TO" = from to period (you must call the function as PERIODSUM(data, type, condition,
from, to) and specify the from and to period either as YYYY-MM or as a number from 1 to 12 in
which case XLReporting will apply the selected year)

"ROLL" = rolling number of periods, relative to (and including) the selected period (you
must call the function as PERIODSUM(data, type, condition, periods) and
specify the number of periods as positive for future periods, or negative for past periods)

Examples:

(assuming the selected period is 2019-03)

PERIODSUM(data,
"PER") returns
the sum for 2019-03

PERIODSUM(data, "YTD") returns the sum for 2019-01 to 2019-03

PERIODSUM(A2:B100,
"PER") returns the sum for 2019-03

PERIODSUM(data, "YTD", Unit="100") returns the sum
for 2019-01 to 2019-03 only for Unit "100"

PERIODSUM(data, "FR.TO", "", "2019-02",
"2019-03") returns the sum for 2019-02 to 2019-03

PERIODSUM(data, "FR.TO", "", 2, 3) returns
the sum for 2019-02 to 2019-03 assuming the selected period falls in 2019

PERIODSUM(data,
"ROLL", "", 3) returns the sum for 2019-03 to 2019-05

Calculates the number of periods that the *from* and *to* periods fall within the
given period range. You can either pass dates, periods (YYYY-MM), or years (YYYY) as
parameters. If you omit either (or both) the *from* or *to* parameter, they will
be assumed to coincide with the start respectively end of the given period range.

*max* parameter if you want the
function to calculate with a different number of periods per year.

PERIODSWITHIN(data, period, from, to, max)

Example:

PERIODSWITHIN("2019-01", "2019-03", "2019-02", "2019-04") = 2

Calculates the year-to-date proportion of the given *amount*, based on the given *year-to-date
period* and the number of periods that the given *from* and *to* periods fall
within the given *year*.

*max* parameter if you want the
function to calculate with a different number of periods per year.

PERIODYTD(data, year, period, from, to, max)

Example:

PERIODYTD(100, "2023", "2023-04", "2023-03", "2023-05") = 66.667

Prompts the user to select a period from a list of periods. This function is required, and
selection is mandatory, if you want to use the **PERIODSUM** functions. Both
functions work together to select and calculate the appropriate amounts based on the selected
period. You need to place PERIODSUM on a field containing periods (YYYY-MM).

The SELECTPERIOD function can be used in different ways, from simple defaults to sophisticated logic:

- By default, the SELECTPERIOD function automatically builds a dynamic list of periods from
the period field that you want to filter on. So it will only show periods that exist in
your data. Optionally, you can provide a different
*source*(data set and field) as well as an optional*filter*. This enables you to generate a list of values fully independent from the field that you want to filter on. - By default, fiscal years are assumed to start at month 1. Optionally, you can pass the
*start*month (1-12) if you use fiscal years that deviate from calendar years. This will automatically adjust the period names and period sums that will be returned by the PERIODNAME and PERIODSUM functions.

**Selecting the source**

The *source* parameter can be a field in a data set (e.g. [Periods:
Period]), a static list of comma-separated values (e.g. "2020-01,2020-02,2020-03"), or an
expression that returns a list of values (e.g. PERIODRANGE("2020", 12).

If you use the *source* parameter, you can also generate a list of years (YYYY), for
example using the YEARRANGE() function. This will present a list of years to the user, whilst
the period amounts will be calculated as if the last month in the year (YYYY-12) had been
selected.

**Selecting the filter**

The *filter* parameter must contain a field in a data set with an operator
and value to match against (e.g. [Periods: Closed] = "N"). You can also use these filter
functions: BETWEEN, CONTAINS, ISANY, ISBLANK, AND, OR, NOT. For more information, see **filter functions**.

You can also watch the tutorial video.

SELECTPERIOD(start, source, filter)

start:

1 - 12 = the 1st month of the fiscal year (optional, 1 = default)

Examples:

SELECTPERIOD() prompts the user to select a period (mandatory)

SELECTPERIOD(4)
prompts the user to select a period (mandatory), with each fiscal year starting in April.

SELECTPERIOD([Periods:
Period]) shows a custom list of periods, with the fiscal year starting in January.

SELECTPERIOD(PERIODRANGE(2020,12))
shows a predefined list of periods, with the fiscal year starting in January.

Returns the given *period* number within the year of the given period.

Optionally,
if you use fiscal years that deviate from calendar years, you can pass the *start* month
(1-12) as an optional parameter. This will automatically adjust the period that will be
returned.

Instead of passing a full period (YYYY-MM), a year (YYYY), or a date in the *data*
parameter, you can also pass a number from -2 to +2 relative to the **current
year** based on today's date (from 2 years before the current year up to 2 years
after the current year). This will return the given period in that year.

*max* parameter if you want the
function to calculate with a different number of periods per year.

SETPERIOD(data, period, start, max)

Examples:

data = "2019-04"

SETPERIOD(data, 12) = "2019-12"

SETPERIOD(data,
12, 7) = "2019-06"

SETPERIOD(0, 5) = "2019-05"

Returns the period based on today's date, plus or minus the given *number* of periods
(optional).

THISPERIOD(number)

Examples:

today = 10-dec-2019

THISPERIOD() = 2019-12

THISPERIOD(-6) =
2019-06

Returns the year based on today's date, plus or minus the given *number* of years
(optional).

THISYEAR(number)

Examples:

today = 10-dec-2019

THISYEAR() = 2019

THISYEAR(-1) =
2018
