What are the standard reports available for Intra &Inter stock transfers.
Also run MB51 but only enter the plant info.
You can then view unplanned plant to plant transfers.
They will have a 303 movement with a storage location from the supplying plant and also a 303 movement without the storage location at the destination plant. If there is a matching 305 movement at the destination plant then the goods have been receipted.
I dumped the data in excel and ran a pivot to show all outstanding transactions. I havent found a SAP transaction that reports on unplanned plant to plant stock transfers.
Hope this helps.
Also I am told MB5TD is available in the latest upgrade. This is the same info as MB5T but with dates shown.
