• What is the cause and solution for SAP error message WRPLCHK001 - Enter an MRP type ?

  SAP Error Message:
  
  WRPLCHK001: Enter an MRP type
  
  Cause:
  This error occurs when you try to process a material in MRP (Material Requirements Planning) without specifying the MRP type in the material master record. The MRP type controls how the material is planned (e.g., consumption-based planning, reorder point planning, etc.). If the MRP type field is empty or not maintained, the system cannot determine the planning procedure for the material, hence the error.
  
  Solution:
  
  
  Maintain the MRP type in the material master:
  
  Go to transaction MM02 (Change Material).
  Enter the material number and select the MRP 1 view.
  In the MRP type field, enter the appropriate MRP type (e.g., PD for MRP, VB for reorder point planning, etc.).
  Save the changes.
  
  
  
  Check the MRP type configuration:
  
  Ensure that the MRP type you enter is valid and configured in the system.
  Use transaction OMI4 to view or maintain MRP types.
  
  
  
  If you are running MRP via transaction MD01/MD02/MD03:
  
  Make sure the material master has the MRP type maintained.
  If you are using a selection variant or batch input, verify that the MRP type is not missing.
  
  
  
  
  Related Information:
  
  MRP Type Field: Controls the planning strategy for the material.
  Common MRP types include:
  
  PD – MRP (Material Requirements Planning)
  VB – Reorder Point Planning
  VV – Forecast-based Planning
  ND – No Planning
  
  
  The MRP type is mandatory for materials that are planned using MRP.
  If the material is not planned, the MRP type can be set to ND (No Planning).
  The error message is typically encountered during MRP runs or when creating planned orders or purchase requisitions.
  
  
  Summary:
  
  Cause: MRP type not maintained in material master.
  Fix: Maintain a valid MRP type in the material master (MRP 1 view).
  Transaction: MM02 to update material master; OMI4 to check MRP types.
  
  
  If you need further assistance, please provide the transaction or process where the error occurs.
