• What is the cause and solution for SAP error message MD101 - No data changed ?

  The SAP error message MD101 "No data changed" typically occurs in the context of Material Requirements Planning (MRP) when you are trying to execute a planning run or make changes to the planning data, but the system finds that there are no changes to be processed. This can happen for several reasons, and understanding the cause can help in resolving the issue.
  Causes:
  
  No Changes in Master Data: The material master data or other related master data has not changed since the last planning run.
  No Demand or Supply Changes: There may be no changes in demand (sales orders, forecasts) or supply (purchase orders, production orders) that would necessitate a change in planning.
  Planning Parameters: The planning parameters set in the MRP run may not have triggered any changes.
  Selection Criteria: The selection criteria used for the planning run may not include any materials that require planning.
  MRP Type: The MRP type of the material may be set in such a way that it does not require planning (e.g., "ND" - No Planning).
  
  Solutions:
  
  Check Master Data: Verify that the material master data has been updated. If there are changes, ensure they are saved correctly.
  Review Demand and Supply: Check if there are any new sales orders, forecasts, or changes in supply that would require a planning run.
  Adjust Planning Parameters: Review the parameters set for the MRP run. Ensure they are appropriate for the materials you are planning.
  Modify Selection Criteria: If you are using specific selection criteria, ensure that they include the materials you want to plan.
  Change MRP Type: If the MRP type is set to "ND" or another type that does not require planning, consider changing it to a type that allows for planning (e.g., "PD" - MRP).
  Run MRP for a Different Scope: If you are running MRP for a specific plant or material, try running it for a broader scope to see if any changes are detected.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like MD01 (MRP Run), MD02 (MRP Run for Single Material), or MD03 (MRP Run for Single Material with Planning File) to initiate planning runs.
  MRP Configuration: Review the MRP configuration settings in SPRO (SAP Project Reference Object) to ensure they are set up correctly.
  Logs and Messages: Check the MRP log for any additional messages or warnings that might provide more context on why no changes were detected.
  SAP Notes: Look for relevant SAP Notes that might address specific issues related to the "No data changed" message.
  
  By following these steps, you should be able to identify the cause of the MD101 error and take appropriate action to resolve it.
