2981313 - S/4HC: Error Plant **** assigned to supplier ******** in T001W. Specify another plant is encountered in App Maintain Business Partner.

• In the Q system, a new plant is created via SSCUI 100066. The plant is assigned to a Supplier via App Maintain Business Partner transaction before the Business Configuration Project (BCP) is released. After the BCP is released, the new plant is transported into the P system.
  
  
• However in the P system, it is not possible to assign the plant to a supplier in App Maintain Business Partner, and the following error occurred: “Plant **** is assigned to supplier ******** in T001W. Specify another plant”. The plant is assigned to a wrong supplier or even a non-existing supplier.
  
  
• There is a requirement to change the supplier assignment of plant **** in the P system. (For e.g. From 00000001 to 00000002), to make sure that the relevant business processes (such as Goods issue of an intercompany process) can run through.

In the P system:

1. Go to App Maintain Business Partner.
2. Select a Supplier.
3. Enter a value for field Plant.

Program Error.

To prevent further inconsistency from happening, consider to assign a new plant (created via SSCUI 100066) to a Supplier in the Q system after the relevant Business Configuration Project is released.
For the existing inconsistent Supplier-Plant assignment in the P system, please follow the below steps:

1. Create a dummy supplier with the supplier number that the plant in question is assigned and save it. 
2. Please pay attention, do not add the plant number directly when trying to create the supplier. The supplier should be created without the plant assigned.
3. Change this dummy supplier by assigning the plant to it in 'Vendor: General Data' (the system will allow it because the supplier number is the same as in the plant data).
4. Change the dummy supplier again by removing the plant (this will also update the plant data).
5. Assign the plant to the supplier that it should be assigned to.

Note: The last step would be to ensure that the dummy supplier is not used in the system (e.g. by setting a block function)
