Hi. I have the same problem:
when i try to post billing document via GM_RRB_IND i get an error
No expenditure items found
Message no. VPK1310
I have done next steps:
1) created sets of sponsored classes and sponsored program
2) assign sets to the appropriate DIP profile
3) assign value types to DIP profile
4) assign sourse GMD1 to DIP profile
4) made billing rule config.
5) assign billing rule in Grant master
6) sales order is created automatically
As I understand data for billing is stored in GMIA table. The data is available (type 99) in this table. But no expenditure items found. Also no expenditure in GM Billing Report (S_ALN_01000534). I do not use WBS or Internal order in expenditure posting. Is it mandatory for RRB in Grant management?
