• What is the cause and solution for SAP error message STGR136 - Cannot reassign; class &1 has no reference plant ?

  The SAP error message STGR136, which states "Cannot reassign; class &1 has no reference plant," typically occurs in the context of class assignments in the SAP system, particularly when dealing with classification and material management.
  Cause:
  This error arises when you attempt to reassign a class (in this case, class &1) to a material or object, but the class does not have a reference plant defined. A reference plant is necessary for certain operations in SAP, especially when dealing with materials that are plant-specific.
  Solution:
  To resolve this error, you need to ensure that the class has a reference plant assigned. Here are the steps to do this:
  
  
  Access the Class in SAP:
  
  Go to transaction code CL02 (Change Class) or CL01 (Create Class) depending on whether you need to create a new class or modify an existing one.
  
  
  
  Select the Class:
  
  Enter the class name (the one indicated in the error message as &1) and press Enter.
  
  
  
  Check Reference Plant:
  
  In the class details, look for the "Reference Plant" field. This is usually found in the "General Data" or "Classification" tab.
  
  
  
  Assign a Reference Plant:
  
  If the reference plant is not assigned, you will need to assign a valid reference plant. This is typically done by entering the plant code in the appropriate field.
  
  
  
  Save Changes:
  
  After assigning the reference plant, save your changes.
  
  
  
  Retry the Operation:
  
  Go back to the operation that triggered the error and try to reassign the class again.
