Unable to Control Half-yearly & yearly Budget in Payment Budget

Hi Expert,

Our Client's requirement is to control the FM Budget on half-yearly as well as yearly in payment Budget category.

Here they want that system will enable to make PR & PO for entire year but at the time of MIGO or ML81N if half-year budget get exhausted it will stop.

Example: They will create PR for SAP Service AMC for full year as 100000*12 month = 12,00,000. But at the time of MIGO or SES system will stop to make any SES if budget will exceed for half-year(100000*6month = 6,00,000).

Which is might be impossible because once budget get consumed at PR level it will not asked for budget again @ MIGO or SES.

I can do the same if activate the commitment budget but they want only payment budget not commitment budget.

Kind Regards

Shyam
