• What is the cause and solution for SAP error message /SAPAPO/ATP137 - Start immediately is only effective if rules-based ATP is active ?

  The SAP error message /SAPAPO/ATP137 indicates that the "Start immediately" option is only effective when rules-based Available-to-Promise (ATP) is active in the system. This error typically arises in the context of Advanced Planning and Optimization (APO) when attempting to perform ATP checks without the necessary configuration.
  Cause:
  
  Rules-Based ATP Not Active: The primary cause of this error is that the rules-based ATP functionality is not activated in your SAP APO system. This functionality is required for the "Start immediately" option to be effective.
  Configuration Issues: There may be configuration settings that are not properly set up in the APO system, leading to this error when trying to execute ATP checks.
  Incorrect ATP Check Settings: The settings for ATP checks in the relevant planning area or product master may not be configured to utilize rules-based ATP.
  
  Solution:
  
  
  Activate Rules-Based ATP:
  
  Go to the SAP APO system and check if rules-based ATP is activated. This can typically be done in the configuration settings under the ATP area.
  You may need to consult with your SAP Basis or APO configuration team to ensure that the necessary settings are enabled.
  
  
  
  Check Configuration:
  
  Review the configuration for the ATP check in the relevant planning area. Ensure that the settings are correctly defined to utilize rules-based ATP.
  You can access the configuration through the SAP Easy Access menu: SAP APO > Advanced Planning > Global Settings > ATP > Define Rules-Based ATP.
  
  
  
  Review Product Master Data:
  
  Ensure that the product master data is correctly set up to use rules-based ATP. Check the relevant fields in the product master that pertain to ATP settings.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test to see if the error persists. Try executing the ATP check again with the "Start immediately" option.
