• What is the cause and solution for SAP error message CM_EAM_TL_API198 - Non-stock material already assigned to task list operation &1 ?

  The SAP error message CM_EAM_TL_API198 indicates that a non-stock material is already assigned to a task list operation in the system. This typically occurs in the context of maintenance planning and execution, where materials are linked to specific operations in a task list.
  Cause:
  
  Non-Stock Material Assignment: The error arises when you attempt to assign a non-stock material (a material that is not managed in inventory) to an operation in a task list, but that material is already linked to another operation or task list.
  Task List Configuration: The task list may have restrictions or configurations that prevent the same non-stock material from being assigned to multiple operations.
  Data Integrity Issues: There may be inconsistencies in the data or configuration settings that lead to this error.
  
  Solution:
  
  Check Existing Assignments: Review the task list and operations to see where the non-stock material is already assigned. You can do this by navigating to the task list in the SAP system and checking the operations.
  Reassign or Remove: If the non-stock material is already assigned to another operation, you may need to either:
  
  Reassign it to the desired operation if it is not critical to the other operation.
  Remove it from the current operation if it is not needed there.
  
  
  Use Stock Material: If possible, consider using a stock material instead of a non-stock material for the operation, as stock materials can be managed in inventory and are less likely to cause assignment conflicts.
  Consult Documentation: Review SAP documentation or help resources for specific guidelines on managing non-stock materials in task lists.
  Check Configuration: If the issue persists, consult with your SAP administrator or technical team to check the configuration settings related to task lists and material assignments.
