  SAP Error Message: WT721
  Text: Check reorder point for the material using reorder point planning
  
  Cause:
  The message WT721 appears when the system detects an issue related to the reorder point (ROP) planning for a material. Specifically, it indicates that the reorder point for the material is either not maintained, incorrectly maintained, or inconsistent with the planning parameters.
  This message typically occurs in the context of reorder point planning (MRP type VB or V1), where the system uses a fixed reorder point and safety stock to trigger procurement proposals.
  Common causes include:
  
  The reorder point (field DISPO - MRP type) is set to reorder point planning, but the reorder point value (field DISMM - Reorder Point) is missing or zero.
  The reorder point is set but does not make sense given the consumption or stock situation.
  The material master data is incomplete or inconsistent for reorder point planning.
  The planning parameters (like safety stock, lot size) are not properly maintained.
  
  
  Solution:
  To resolve the WT721 message, follow these steps:
  
  
  Check the MRP type:
  
  Go to transaction MM02 (Change Material Master).
  Navigate to the MRP 1 view.
  Verify that the MRP type is set to reorder point planning (e.g., VB or V1).
  
  
  
  Maintain the Reorder Point:
  
  In the same MRP 1 view, check the Reorder Point (DISMM) field.
  Ensure that a valid reorder point value is entered (greater than zero).
  The reorder point should be based on historical consumption and lead times.
  
  
  
  Check Safety Stock:
  
  In the MRP 2 view, verify the safety stock (field SALO).
  Safety stock should be maintained appropriately to avoid stockouts.
  
  
  
  Review Lot Size:
  
  In MRP 1 view, check the lot size indicator and lot size values.
  Ensure the lot size is consistent with reorder point planning.
  
  
  
  Run MRP again:
  
  After correcting the reorder point and related parameters, run MRP (transaction MD01 or MD02) again.
  The system should now be able to generate procurement proposals without the WT721 message.
  
  
  
  Additional Checks:
  
  Verify that the material is relevant for MRP.
  Check if the plant and storage location data are correctly maintained.
  Review consumption data to ensure reorder point is realistic.
  
  
  
  
  Related Information:
  
  
  Reorder Point Planning (MRP Type VB or V1):
  
  This is a simple planning method where procurement proposals are generated when stock falls below a predefined reorder point.
  
  
  Fields involved:
  
  MRP Type (DISPO)
  Reorder Point (DISMM)
  Safety Stock (SALO)
  Lot Size (BESKZ)
  
  
  
  Transactions:
  
  MM02 - Change Material Master
  MD01/MD02 - Run MRP
  MD04 - Stock/Requirements List (to check planning results)
  
  
  
  SAP Notes and Documentation:
  
  SAP Help Portal on MRP and reorder point planning.
  SAP Notes related to WT721 (if any specific notes exist for your SAP version).
  
  
  
  
  Summary:
  WT721 warns that the reorder point for a material planned with reorder point planning is missing or incorrect. To fix it, maintain a valid reorder point in the material master and ensure all related planning parameters are consistent. Then rerun MRP to generate correct procurement proposals.
