Reservation for WBSE

Hi,

The scenario is....

Material A has Material Master setting as procurement F and Collective stock indicator (Assume I can not make it individual). Requirement is created from Project and material is delivered after receipt.

I assign Material to my Project activity and create Reservation against the WBSE.

During MRP run, since stock is not available in plant , it creates a PR.

After PR is converted to PO and GR is posted, it sits in plant stock.

Later it is issued against the reservation created from PS.

Whether it will be available in stock or since issue is consumption will there be no stock.? if that is true how can I deliver with no stock ? What is procedure to close that reservation ?

Thanks
