• What is the cause and solution for SAP error message PPH_MASTER_DATA002 - MRP controller &1 in plant &2 cannot be deleted: &3 matls still assigned ?

  The SAP error message PPH_MASTER_DATA002 indicates that you are trying to delete an MRP (Material Requirements Planning) controller in a specific plant, but the system is preventing this action because there are still materials assigned to that MRP controller. The message provides the following details:
  
  &1: The MRP controller that you are trying to delete.
  &2: The plant from which you are trying to delete the MRP controller.
  &3: The number of materials still assigned to the MRP controller.
  
  Cause
  The primary cause of this error is that the MRP controller you are attempting to delete is still linked to one or more materials in the system. In SAP, MRP controllers are used to manage the planning and procurement processes for materials, and as such, they cannot be deleted if they are still in use.
  Solution
  To resolve this error, you need to follow these steps:
  
  
  Identify Assigned Materials:
  
  Use transaction code MM03 (Display Material) or MM02 (Change Material) to check which materials are assigned to the MRP controller.
  You can also use transaction code SE16N to query the relevant tables (e.g., MARC for plant data) to find materials linked to the MRP controller.
  
  
  
  Reassign or Remove MRP Controller from Materials:
  
  For each material that is assigned to the MRP controller, you will need to either:
  
  Change the MRP controller to a different one using transaction code MM02.
  Remove the MRP controller assignment if it is no longer needed.
  
  
  
  
  
  Delete the MRP Controller:
  
  Once all materials have been reassigned or the assignment has been removed, you can proceed to delete the MRP controller using transaction code OMC1 (for MRP controllers).
