Question

The following error message appears in pc_server log or in the xxx50/scratch/ ue_01 log or in a p_manage_50 log:
Oracle error: io_z07_write
ORA-00001: unique constraint (xxx01.Z07_ID) violated

What is this message about and how to avoid it?

Answer

This indicates that an attempt to create a Z07 (indexing request) for a particular doc record has failed because a Z07 already exists for this doc #. The system intentionally prevents a second z07 for the same doc number from being written (to avoid unnecessary processing).

Since this duplicate Z07 doesn't really *need* to be written, this message can be ignored.
