• What is the cause and solution for SAP error message /SCMB/MC_PB_DEF156 - Nothing changed ?

  The SAP error message /SCMB/MC_PB_DEF156 with the description "Nothing changed" typically occurs in the context of SAP Advanced Planning and Optimization (APO) or Supply Chain Management (SCM) when there is an attempt to execute a planning function or a data update, but the system determines that there are no changes to be processed.
  Causes:
  
  
  No Data Changes: The most common cause is that the data being processed has not changed since the last execution. This can happen if the planning run is executed without any new data or if the data has not been updated in the relevant master data or transaction data.
  
  
  Incorrect Selection Criteria: The selection criteria used for the planning function may not match any records, leading to no changes being detected.
  
  
  Planning Area Configuration: The planning area may not be correctly configured, or the key figures may not be set up to allow for changes.
  
  
  Execution of Redundant Functions: If the same planning function is executed multiple times without any changes in the underlying data, the system will return this message.
  
  
  Solutions:
  
  
  Check Data Changes: Ensure that there are actual changes in the data that you expect to be processed. This may involve checking the source data or the planning book to confirm that updates have occurred.
  
  
  Review Selection Criteria: Verify the selection criteria used in the planning function. Make sure that they are correctly set to include the relevant data.
  
  
  Reconfigure Planning Area: If necessary, review the configuration of the planning area and key figures to ensure they are set up correctly to capture changes.
  
  
  Run Planning Functions Appropriately: Avoid running the same planning function multiple times without changes. Instead, run it only when there are new updates or changes in the data.
  
  
  Check Logs and Messages: Review any logs or additional messages that may provide more context about why the system is indicating that nothing has changed.
