Message of active PID blocking the creation of new one

Hi All,

Please, help me to solve this issue.

I have successfully created, counted and posted a PID for a material in December 2014, as usually done every month since 2013.

However, when creating a new PID for the same in January 2015, I get a message that  a PID is already active for the Batch.

I deleted the PID for December 2014, assuming it was the one causing the problem but still the same message.

I run MI22 and there is no PID with active status in the list!

Please HELP.

Thanks

Cyril
