Hi!

Most likely you have 2 parallel processes of SFC release that generate the same IDs for SFCs. SFCs should be unique across entire ME database.

I would check Next Number patterns first.

Regards,

Thank you Sergiy:

This error message concernes only one material, that must have one next number pattern,

I want to remind that the tester contains 16 slots , one slot per produit, the tester application generate an SFC for each new product

for you, the error is due to simultaneous call ?

thank you

If you are using DM520 at testers to generate SFC ID, then I believe it is quite possible that parallel calls can cause such issue. The error message just tells that someone is trying to create an SFC with the ID that is already exists in the database. So, if 2 testers enter the same ID in POD and trigger DM520, I would expect one of these calls to fail with such error.
