We have a project in production system PXXXX where from PO YYYY activity was deleted the materials. The problem is that this deletion was done before the materials was returned into the stock by cancellation of material document NNNNNN (movement type 282). Now the system doesn't let to cancel this document because this two item with the used reservation numbers was deleted from the project. Now we are not able to cancel material doc NNNNNN what is necessary to be able to make goods issue on another project (sales order ). What we can do to be able to return this two items in stock from this material doucument?
