unable to pick Invoice by PPR

Hi ,

we are trying to test one issue in the test instance afyter fix however ppr is not selecting Invoices with payment method as 'Check'.

checked the set ups of payment Document and PPR which are already using onec,

1)creating invoices against one supplier

2)validating and accounting that

3) submitting ppr with the payment document , ppp which are used by business

4)However not picking single invoice.... is the issue

Tried changing payment document other not picking ......its picking all invoices if we are not specifying payment document as 'Check' ,electronic hou ever the PPP is for check hence failing ...

Please let us know which set up  or which issue stopping selcting an invoice  in PPR submission.
