Enabling “Negative On-Hand Allowed” on the inventory part is a mandatory prerequisite for using the Catch Unit feature.
However, during testing:
- configured an inventory part with Catch Unit enabled
- The “Negative On-Hand Allowed” option was not enabled
- I successfully completed the full Order-to-Cash process (CO → Shop Order → CO Delivery → Invoicing)
No validation, warning, or error was triggered at any stage of the process.
Concern:
This behavior appears to contradict the documentation, which states that the setting is required.
Is the “Negative On-Hand Allowed” parameter truly mandatory for Catch Unit usage? If yes, in which specific scenarios is it enforced? If not, should the documentation be updated to reflect the actual system behavior?
Please advise on whether this is expected behavior or a documentation inconsistency.
