RKU3 not reach the derivation during using tcode FMB0
I used tcode FMB0 to execute subsequent posting CO doc. to Funds Management.
Funds Management activated on 27.06.2009, and the reposting line item doc. (business transaction RKU3-tcode KB61) already posted before FM activated.
The reposting line item doc. can not updated to FM because derivation funds centre/commitment item not happen. I test with activate tracing. It is only happen to business transaction RKU3. If RKU1 post also before FM activated, it is updating to FM successfully.
I wonder why (only) RKU3 can not read the derivation when executing FMB0. I try to use supplementary account assignment tcode FMCN to assign the acct.assignment before copy CO doc. However no field CO document exist.
Have idea to resolved this issue?
