You have configured your Flexible workflow for Purchase Requisitions at item level.
In the APP 'My Inbox' you have the possibility to process multiple entries at the same time.
When using this option for several PR items simultaneously, you receive a pop up stating.
'Some items were not processed correctly' and 'X number of tasks not processed'
If you re-process the selected items they are completely processed after one or more attempts.

Reproducing the Issue
1) Go to 'My Inbox'
2) Choose the task type 'Release of Purchase Requisition Item'
3) Select several items from one or more Purchase Requisitions
4) Choose 'Approve' or 'Reject'
5) Not all items are processed
Standard System Behaviour.
When the work items are released together on mass, the system triggers several background work processes simultaneously.
The Purchase Requisition status and other field values need to be updated so the system sets an exclusive lock
on the purchase requisition. Each work item is processed in sequence and attempts to update the corresponding
Purchase Requisition Item. If the document is locked this update will not be possible and the task will not be
processed as a result. When processing several items from the same Purchase requisition lock conflicts are inevitable.
It is recommended that PR item approvals are processed individually to avoid lock conflicts.
Note* There is also the option to manage your workflow procedure at header level for PR's.
