• What is the cause and solution for SAP error message XC108 - &1: Plant &2 is an external plant ?

  The SAP error message XC108 indicates that the plant specified in the transaction is recognized as an "external plant." This typically means that the plant is not part of the internal organizational structure of the company code or is not configured correctly in the system.
  Cause:
  
  External Plant Configuration: The plant may be set up as an external entity in the system, which means it is not intended for internal transactions.

  Solution:
  
  
  Check Plant Configuration:
  
  Go to the plant master data (transaction code OX10 or OX18) and verify the settings for the plant in question. Ensure that it is configured correctly for your company code and that it is not marked as an external plant if it should be internal.
