• What is the cause and solution for SAP error message M3423 - Reorder level requires MRP type ?

  The SAP error message M3423, which states "Reorder level requires MRP type," typically occurs in the context of Material Requirements Planning (MRP) when you are trying to set up or manage materials that have a reorder level but do not have a defined MRP type. This can prevent the system from properly calculating the reorder point and managing inventory levels.
  Cause:
  The error is caused by the absence of an MRP type for the material in question. The MRP type is essential for the system to understand how to plan and manage the material's inventory levels, including when to reorder stock based on the defined reorder level.
  Solution:
  To resolve this error, you need to ensure that the material has a valid MRP type assigned. Here are the steps to do this:
  
  
  Access Material Master Data:
  
  Go to the transaction code MM02 (Change Material) or MM01 (Create Material) in SAP.
  
  
  
  Select the Material:
  
  Enter the material number that is causing the error.
  
  
  
  Select the MRP View:
  
  Navigate to the MRP view (usually view 1 or 2, depending on your configuration).
  
  
  
  Assign MRP Type:
  
  In the MRP type field, select a valid MRP type (e.g., PD for MRP, VB for consumption-based planning, etc.) that suits your planning requirements.
  
  
  
  Save Changes:
  
  After assigning the MRP type, save the changes to the material master.
  
  
  
  Recheck the Process:
  
  After making the changes, try to execute the process that triggered the error again to ensure that the issue is resolved.
