How to get the Cumulate Value in Data action - SAP Analytic cloud

[brahmareddy_kolli]

Hi Experts,

I need your help with a data action. I’ve tried several approaches, but have had no luck.

I have three measures: Periodic Cost, Cumulative Cost, and Flag. I want to accumulate the values of Periodic Cost from previous periods and post them into the Cumulative Cost measure for the period marked by the Flag measure (where the Flag value is always "1" for the FLAG Measure).

List of Dimensions : Product, version, date , product and Measure

for example 

Source Values
Product	Measures	202501	202502	202503	202504	202505	202506	202507	202508	202509	202510	202511	202512	Total
Product1	Periodic COST	1000		3000		500								4500
Product1	FLAG							1
Product2	Periodic COST		500		650		50							1200
Product2	FLAG											1
Expected Values
Product1	Cumulate COST							4500	4500	4500	4500	4500	4500
Product2	Cumulate COST											1200	1200

Step 1: Calculate Cumulative Cost in a Variable

Step 2: Calculate Cumulative Flag as well to simplify. If blank, 0.

Multiply Cumulative Amount and Flag.

Your result would be something like this.

		2025.01	2025.02	2025.03	2025.04	2025.05	2025.06	2025.07	2025.08	2025.09	2025.1	2025.11	2025.12
	Time
Product	Measures
Product_1	Amount	1000		500		3000
Product_1	Flag						1
Product_1	Acc_Amount (Variable)	1000	1000	1500	1500	4500	4500	4500	4500	4500	4500	4500	4500
Product_1	Acc_Flag (Variable)	0	0	0	0	0	1	1	1	1	1	1	1
Product_1	Amount_YTD	0	0	0	0	0	4500	4500	4500	4500	4500	4500	4500

Sample code to get Accumulated sum using Advanced Formula:

FOREACH [d/Date]
	IF [d/Date].[p/FISCAL_PERIODDESC] = "P01" THEN
		DATA([d/Measures] = #ACC_AMOUNT) = RESULTLOOKUP([d/Measures] = "PERIODIC_AMOUNT")
	ENDIF
	DATA([d/Measures] = #ACC_AMOUNT) = RESULTLOOKUP([d/Measures] = #ACC_AMOUNT, [d/Date] = PREVIOUS()) + RESULTLOOKUP([d/Measures] = "PERIODIC_AMOUNT")
ENDFOR

Two options:

1. Use VARIABLEMEMBER of time dimension in advance formula to collect total.
2. Define calculated measure in with YTD syntax in model and use copy step in data action to copy cover.

I couldn't proceed with the Calculated Measure and Copy Step.

How can I identify the Flag Account and post the YTD amount for the particular month?

As I mentioned, there are three accounts: Periodic Cost, Cumulative Cost, and Flag Account (where we need to post values for the particular month).

VARIABLEMEMBER is not getting the previous months data
