Hi Ming:
Issue is not in PR. We have tested PR reassignment for all material related PRs, its working fine. However PRs with account assignment category K are not showing up error although i change commitment item target field with "overwrite with new values" . System is issuing error message
Reassignment of account assignment element Commitment Item not possible
Message no. FMCF108
It says to make reassignment derivation strategy (i have defined none for it) and account assignment derivation strategy compatible.
For PO related issue my point is why is system not inheriting reassigned PR FM Account assignment when creating PO with reference to it. At PO it is taking value from FMDERIVE.
Regards
