Serial number already locked by the user in Production order

[pradeepkumar21]

Dear Experts,

When generating serial numbers using the newly created serial number in the production order, I encounter an error stating that the serial number is already locked by a user. However, upon checking in SM12, there are no lock entries for any user.

Regardless of the quantity of serials being generated, the system continues to display this error. Could you please advise on how to resolve this issue?

Hello @pradeepkumar21 

It's hard to tell without access to your system. There is a couple of notes related to IS140 "Serial number &1 is already locked by user &2" message:

Why don't you start by reviewing them?

Best regards

Dear All,the issue has been resolved, turns out the business was using a custom serial number range which was casuing the issue.After maintaining the correct number range i am able to generate the serials.
