error while posting confirmation for limit PO

Hi Experts,

we are having a standalone scenario(SRM 7) and the issue is as mentioned below

The situation is that the PO is a limit order with 2 line items. The first line item is complete and has been closed off with the u201Cno further confirmation/invoiceu201D indicators selected. However the 2nd line still has some limit remaining but the when the central confirmations attempts to enter a good receipt against the line they get an error message which is "No Confirmation could be entered for purchase order"

please guide me how to solve this.

regards

smita
