How can I retrieve the previous month’s measure output in Incentive Compensation?

You can use the predefined Previous Interval Attainment custom function to copy a plan from 2024 to 2025.

However, if there are 2 different compensation plan assignments such as Comp Plan FY24 and Comp Plan FY25, the predefined Previous Interval Attainment function won’t work because one of the input parameters is SRP_COMP_PLAN_ID, which is unique for each compensation plan assignment.
