• What is the cause and solution for SAP error message MM064 - The maximum stock level is not used with this lot-sizing procedure ?

  The SAP error message MM064, which states "The maximum stock level is not used with this lot-sizing procedure," typically occurs in the Materials Management (MM) module when there is a configuration issue related to the lot-sizing procedure for a material.
  Cause:
  This error arises when the system is configured to use a lot-sizing procedure that does not support the maximum stock level setting. The maximum stock level is a parameter that can be set for materials to control inventory levels, but not all lot-sizing procedures take this parameter into account. Common lot-sizing procedures that do not utilize the maximum stock level include:
  
  Lot-for-lot (L4L)
  Reorder point (ROP)
  
  If a material is assigned a lot-sizing procedure that does not support the maximum stock level, and you attempt to use that maximum stock level in your planning, the system will generate this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Lot-Sizing Procedure:
  
  Go to the material master record (transaction code MM03) and check the lot-sizing procedure assigned to the material in the MRP (Material Requirements Planning) view.
  If the lot-sizing procedure does not support maximum stock levels, consider changing it to one that does, such as:
  
  Fixed lot size
  Periodic lot size
  Optimal lot size
  
  
  
  
  
  Adjust Maximum Stock Level:
  
  If changing the lot-sizing procedure is not feasible, you can also consider removing or adjusting the maximum stock level for the material. This can be done in the material master record under the MRP view.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP MM consultant to understand the implications of changing the lot-sizing procedure or the maximum stock level.
  
  
  
  Testing:
  
  After making changes, perform a test run of the MRP to ensure that the error is resolved and that the planning runs as expected.
  
  
  
  Related Information:
  
  Lot-Sizing Procedures: Understanding the different lot-sizing procedures and their implications on inventory management is crucial. Each procedure has its own characteristics and is suited for different business scenarios.
  Material Master Data: The material master is a central repository of information related to materials, and it is essential to maintain accurate and relevant data for effective inventory management.
  MRP Configuration: Familiarize yourself with MRP configuration settings in SAP, as they play a significant role in how materials are planned and managed.
