• What is the cause and solution for SAP error message SGT_MAIN253 - Rules can not be displayed at ATP: Define Pool Segment and Check Level ?

  The SAP error message SGT_MAIN253, which states "Rules cannot be displayed at ATP: Define Pool Segment and Check Level," typically occurs in the context of Advanced Planning and Optimization (APO) or Advanced ATP (aATP) when there is an issue with the configuration of the pool segment or the check level in the system.
  Cause:
  
  
  Missing Configuration: The error often arises when the necessary configuration for the pool segment or check level is not defined in the system. This could mean that the system is unable to find the relevant rules or settings that govern how ATP checks are performed.
  
  
  Incorrect Settings: If the settings for the pool segment or check level are incorrect or incomplete, the system may not be able to display the rules associated with them.
  
  
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to view or access the rules related to ATP checks.
  
  
  Data Inconsistencies: There may be inconsistencies in the master data or configuration data that prevent the system from displaying the rules.
  
  
  Solution:
  
  
  Check Configuration:
  
  Navigate to the configuration settings for ATP in the SAP system.
  Ensure that the pool segment and check level are properly defined. You can do this by going to the relevant customizing transaction (e.g., SPRO) and checking the settings under the Advanced Planning or ATP sections.
  
  
  
  Define Pool Segment:
  
  If the pool segment is not defined, you will need to create it. This involves specifying the relevant parameters and ensuring that it is linked to the appropriate materials and planning strategies.
  
  
  
  Define Check Level:
  
  Similarly, ensure that the check level is defined correctly. This includes specifying how the system should perform ATP checks and what rules should apply.
  
  
  
  Authorization Check:
  
  Verify that the user encountering the error has the necessary authorizations to access the ATP rules. This may involve checking user roles and permissions in the SAP system.
  
  
  
  Data Consistency Check:
  
  Perform a consistency check on the master data and configuration data related to ATP. This may involve running specific reports or transactions to identify and resolve any inconsistencies.
