Error 078F Insert to Table F4301Z failed.

Hi,

Error: 078F Insert to Table F4301Z failed, comes during the Generate PO from Requisition.

Cause:The record being inserted into table F4301Z already exists or you do not have authority to insert records into this table.
RESOLUTION: Verify that the record being added doesn't already exist and that you have proper authority. Check the JDE.LOG and
JDEDEBUG.LOG for additional information

Can any on tell me how to resolve that error?

what i got is:

There are two possible causes:

1. This error will be received if UDC 00/RR is missing P43060, Generate PO from Requisition.
