Goods receipt through Inbound delivery for Sub-Contracting Purchase order

Hi

I am trying to do goods receipt for the inbound delivery /shipping notification created for a sub -contracting Purchase order. The Finished product and the component part are batch managed, When I try to perform PGR in VL32N , I am getting a blank screen as error message and Goods receipt is not getting triggered . I checked for OSS note and found 645119 close to my issue but not an exact match . We are in ECC 6.0 with EHP 4. Can some one clarify whether it is possible to post GR through inbound delivery for a Subcon Purchase order .

Thanks in advance for your immediate response.

with regards,

Joseph Anand B
