Goods receipts/goods issue

Hi Experts,

Goods Receipt of a work order is blocked when goods issue is not completed for all componenets of the work order BOM

Problem :

If there are backflush components on the operation which triggers auto GR,then with confirmation of the operation system wants to do Gi and Gr at the same time . The GR is blocked due to open GI and then we get an error message when doing the confirmation of operation and as well as we get a COGI entry for movement 101
