Value set based account rule is working with PPM TAD and JERS but not working with AP & PO TAD

AP & PO TAD is not deriving the Item expense/Charge account after replacing COA based account rule with Value set based account rule. Are there any limitations in using Value-set based account rules created in PPM to be used in AP and Purchasing? Appreciate your help in resolving this issue.

Example (AP invoice): Clicking on ‘Derive account’ in a Project based AP invoice is not filling project distributions in Invoice line distributions with message line AP_NO_TAB and validation status turning to 'Needs revalidation'

Example (PO): Getting below errors when saving a project PO

Error Message text:

The account (PO Variance Account) Couldn't be determined. (PO-2055355).
