Payment Block 'R' Invoice verification for vendor Invoices
In our environemnt, vendor invoices are being posted through IDOCS.
For a PO with "GR based IV' it is sometimes seen that the GR processor reverses a material document (MBST) and then carries out another GR correctly.
In the interim when an invoice is posted, system blocks it with 'R' Invoice verification. I've checked the time of the Invoce document creation and the correct GR, it is seen that invoices are posted after the GR has happened.
My questions are as below :
1) When there is a correct GR (material document) available with the correct quantity, why does the system blocks the invoce ?
2) We also have program RM08RELEASE running in background. The batch job variant has processing 'Release Automatically' and Blocking procedure 'Blocked due to Variances' selected. But it does not relaese the invoices which has Payment Block 'R' Invoice Verification
Any inputs for the above questions would be very helpful.
