Data Transfer Routine

Hi,

We have a requirement i,e In third party sales scenario we want to make a invoice based on each Good's Receipt Document ( Material Document ) for this we are trying to write a routine but could not able to succeed as we are not able to restrict one GR in invoicing its clubbing all the GR's happened.

Ex: If there is one Sales Ord with one line item and coressponding one Purcase order based on SO & If there are two GR's happened against this PO. Then while invoicing it is clubbing the material in the two GR documents, Where as we want only only invoice for one GR. ( One unique invoice for one unique GR )

If anybody finds solution for this kindly help us. Point's rewarded.

Thank's
