• What is the cause and solution for SAP error message MD135 - Replacements in overlapping periods is not possible ?

  The SAP error message MD135, which states "Replacements in overlapping periods is not possible," typically occurs in the context of Material Requirements Planning (MRP) when there are issues with the replacement of planned orders or stock in overlapping time periods. This error can arise in various scenarios, such as when trying to replace a planned order with another planned order that has a conflicting time frame.
  Cause:
  
  Overlapping Time Periods: The primary cause of this error is that the replacement order you are trying to create overlaps with an existing order or stock in a way that is not allowed by the system.
  Incorrect Configuration: There may be configuration settings in the MRP or in the material master that do not allow for overlapping replacements.
  Planning Parameters: The planning parameters for the material may not be set correctly, leading to conflicts in the scheduling of orders.
  Stock Levels: If there are stock levels that conflict with the planned orders, this can also trigger the error.
  
  Solution:
  
  Check Order Dates: Review the dates of the planned orders and ensure that they do not overlap. Adjust the dates of the orders if necessary.
  Review MRP Settings: Check the MRP settings for the material in question. Ensure that the settings allow for the type of replacements you are trying to perform.
  Adjust Planning Parameters: If the planning parameters are causing the issue, consider adjusting them to allow for more flexibility in order replacements.
  Use Alternative Solutions: If the replacement is not feasible, consider using alternative solutions such as creating a new order instead of replacing an existing one.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling replacements and MRP settings.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like MD04 (Stock/Requirements List) to analyze the stock and requirements situation for the material.
  Material Master: Check the material master data (transaction code MM03) for any settings that might restrict replacements.
  MRP Type: Review the MRP type assigned to the material, as different MRP types can have different rules regarding order replacements.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional guidance on handling replacements in MRP.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in MRP processes.
