Hi Zakir,
when you releasing the budgeting, the budget value is being stored in both CO area currency and object currency. Database update is done for table BPGE (overall total), BPJA, BPPE, BPEG, BPEJ, BPEP and in the project info database.
In this table, the CO area currency and the object currency are represented by ledger numbers (field LEDNR). The value of this field is determined in function KBPS_FIND_LEDGER.
Regards, Gordon
