Hi @MelTanyaS,

Could it be that there are automations on the purchase order or other related entities?

I’ve had a similar problem in the Cloud version and it turned out that some processes (Incoming Customer Orders) Do not fare well when automation is doing changes in the meantime.

Thank you for your reply @JoDe 

How can i investigate on it? Can you give some advice on how you found the source of the error and how you tackled it plz? 

Thanks 

Tanya

@MelTanyaS,

We have multiple environments.

On a test environment:

Do a quick test first. Disable all event actions and do the test scenario, does it work? Then it is likely a similar problem. Re-enable them again.

1. We made an export of all event actions
2. We made a ranking of which entities were more likely to impact the process
3. opened 2 sessions, in one we have the event actions which we disable one at a time. On the other session we have the process at the step where we were getting the issue.
4. At this point you will have to disable an event action → press the save button.
5. Rinse and repeat until it does work
6. After you find which causes the issue when enabled, re-activate all the previous ones and try again. Sometimes the issue can be caused by multiple items.
