Hi,
I would suggest to create a new storage location under the same plant for rig and then transfer post the goods to the new storage location using MB1B transaction with 311 movement. Here, since the storage location is under same plant, it wont generate any accounting entry.
Issue the material against order (261) or cost center (201) in MB1A or MIGO - Goods Issue; when the material is required for consumption. The accounting document will be generated at this point.
Revert back in case of any issues.
Regards,
AKPT
