Hi,
We can create PO with or without account assignment category based on the configuration and the master data. If you are creating PO for a material with master data, with account assignment and without item category, system will always allow. If you are using item category in the same case, you have to define account assignment and item category combination in OMG0 transaction.
If you are creating PO for material without master data, system will always ask for account assignment.
If the system still throwing error, please share the error message number.
Regards,
AKPT
