AP Logged Voucher - Additional Info - Batch completes in error

We are on OW 9.0.   Entering a logged voucher (P0411), form exit to Additional Info and add PO number/type/coy, post batch, post report shows that journals created successfully, however, message in Work Centre that batch completed with errors.

'The record being processed either already exists for an 'ADD'

function or does not exist for an 'INQUIRY', 'CHANGE' or

'DELETE' function' and

'ERROR: File can not be accessed.

Solution. . . Change IBM security or authority using the IBM EDTOBJAUT command'.

Subsequently, when matching the voucher to the PO (two way match), and then posting, same error received and the Amount Relieved in F4311 and records are not created in F43199.
