Purge WFERROR items with the parent_item_type = 'PAAPINVW' and parent_item_key = '#SYNCH'

Parent Item type - 'PAAPINVW'

Parent Item Key - '#SYNCH'

Workflow - "Project Supplier Invoice Account Generation"

We see many WFERROR items in the wf_items table, with the above mentioned parent_item_type and parent_item_key.

This 'PAAPINVW' workflow does not store all the other details in any other workflow tables, like wf_item_attribute_values; and the item_key '#SYNCH' gets generated and logged into WF tables only on certain conditions. I believe this specific item_type and item_key does not store any dependent information apart from wf_items. I don't see any relevant values in the wf_item_attribute_values table as well. This table has no rows when queried for the item_type as  'PAAPINVW'
