• What is the cause and solution for SAP error message /SCF/CL_MDL_MESSAGES052 - Maximum number of selection lines has been reached ?

  The SAP error message /SCF/CL_MDL_MESSAGES052 Maximum number of selection lines has been reached typically occurs when a user tries to create or modify a selection screen in a report or transaction, and the number of selection criteria exceeds the allowed limit set by the system.

  Solution:
  
  Reduce Selection Criteria: Review the selection criteria you are using and try to reduce the number of lines. Combine similar criteria where possible.
  Use Ranges: Instead of specifying multiple individual values, consider using ranges or intervals to consolidate your selection criteria.
  Modify the Report: If you have access to the report's code, you may need to modify it to handle selection criteria more efficiently. This could involve changing how selections are processed or allowing for more lines if feasible.
  Check for Custom Enhancements: If the error occurs in a custom report, review the custom code to ensure it adheres to SAP's best practices regarding selection screens.
