Issue in ordering PO from SRM with NO further invoice check

Hi All,

We have implemented SRM 7.13 with SP01 and facing the below issues:

1) We have ordered PO and created GR & Invoice.

2) After Gr and invoice , we have made no further confirmation and no further incvoices checked.

3) Status of PO is changing to ERROR in PROCESS and getting the error as"PO 4400000047: System error invoking ADDR_NUMBER_GET: return code  1".

Can you please let me know how to clear this issue.

Thanks,

Ankur
