• What is the cause and solution for SAP error message STEP636 - &1 is already assigned to plant &2. Additional plant &3 ignored ?

  The SAP error message "STEP636 &1 is already assigned to plant &2. Additional plant &3 ignored" typically occurs in the context of material master data or production planning when you are trying to assign a specific step (like a routing step or a production process) to multiple plants, but that step is already assigned to one of the plants.
  Cause:
  
  Duplicate Assignment: The step (e.g., a routing step or a production process) you are trying to assign is already linked to a specific plant. SAP does not allow the same step to be assigned to multiple plants simultaneously.
  Configuration Error: There may be a configuration issue where the system is not set up to allow the desired assignment.
  Data Integrity: The data being processed may have integrity issues, leading to conflicts in assignments.
  
  Solution:
  
  Check Existing Assignments: Review the existing assignments for the step in question. You can do this by navigating to the relevant transaction (like CA03 for routing) and checking the details for the step assigned to the plant.
  Modify Assignments: If you need to assign the step to another plant, you may need to remove the existing assignment from the first plant or create a new step that can be assigned to the additional plant.
  Use Different Steps: If the business process allows, consider creating a new step that can be assigned to the additional plant without conflicts.
  Consult Documentation: Review SAP documentation or help files related to the specific module you are working with (like Production Planning, Material Management, etc.) for more detailed guidance.
  Check Configuration: If you believe this is a configuration issue, consult with your SAP Basis or configuration team to ensure that the system is set up correctly for your business processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CA03 (Display Routing), CA02 (Change Routing), or others depending on the context of the error.
