The item is not relevant for billing.

Hi,

I have created return sales order type which is copy of RE. I have done PGR but while creating invoicing based on return sales order number or return delivery doc. number .... error log is coming as Item is not relevant for billing. I checked all config setting but all vain. System message is VF- 044. What could be the reason of it. can any body suggest in this matter.

Thanks in advance.

Regards,

Savi
