Cumulation ID with HRFORMS

Hi,

I'm using "HRFORMS" transaction for create payslips. With "PE51" transaction, you can define cumulation ID. This cumulation ID could be wage types, evaluation class 02 value or another cumulation ID. But in "HRFORMS" transaction, I only found the cumulation WT tab where you can enter only wage types individually. If I must fill the tab for each 02 evaluation class value, maintaining this table would be much more complex (for example when I create new WTs).

Does anyone know how to create cumulation ID like in PE51?

Regards,

Jaime
