SAP Note 23687 - MMBE: GR blocked stock

Symptom:

The stock overview (transaction MMBE) displays the GR blocked stock. This stock is calculated from the total of all goods receipts for purchase orders into GR blocked stock of this material (movement types 103 and 106) for which the transfer into the own stock or the return delivery to the vendor (movement types 105 and 104) was not yet entered. In this case, only those order items are considered whose goods receipt to the stock is to be posted to the material master. No special stocks are considered except for the vendor consignment stock.

Cause and prerequisites

This function is defined this way. The GR blocked stock should contain the stock quantity which can be used without restrictions after its release.

Solution
If the GR blocked stock is to be calculated differently, a modification is required.
