Check Number Problem

Dear Experts,

While making outgoing payment through check via Tcode FPY1 , payment is happening and updated also in FPL9 but no check number is coming while checking the transactions.

I have configured everything in check management and also created format for the outgoing check but while checking the transaction neither checks nor check numbers are coming.

Can anyone please provide some guidance to get the printed checks and check number for outgoing payment.

Thanks in advance

Regards

Kumar
