• What is the cause and solution for SAP error message ED196 - Patterns may only be up to 100 lines ?

  The SAP error message ED196, which states "Patterns may only be up to 100 lines," typically occurs in the context of SAP's data processing, particularly when working with data transformation or mapping in tools like SAP Data Services or SAP PI/PO (Process Integration/Process Orchestration). This error indicates that a pattern or mapping definition exceeds the maximum allowed limit of 100 lines.
  Cause:
  
  Exceeding Line Limit: The primary cause of this error is that the pattern or mapping you are trying to create or execute has more than 100 lines of code or configuration. This limit is imposed by the system to ensure performance and maintainability.
  Complex Mapping Logic: If the mapping logic is complex and requires multiple lines of code, it can easily exceed this limit.
  
  Solution:
  
  Simplify the Mapping: Review the mapping logic and try to simplify it. Break down complex transformations into smaller, more manageable pieces. This may involve creating multiple smaller mappings instead of one large one.
  Use Functions: If possible, utilize built-in functions or reusable components to reduce the number of lines in your mapping.
  Refactor Code: If you are using custom code or scripts, consider refactoring them to reduce the number of lines. This might involve consolidating logic or removing unnecessary lines.
  Check for Redundancies: Look for any redundant or repetitive lines in your mapping and eliminate them.
  Consult Documentation: Refer to SAP documentation or community forums for best practices on mapping and transformation to ensure you are using the most efficient methods.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to this error. Sometimes, SAP releases updates that may change the limitations or provide alternative solutions.
  Performance Considerations: Keep in mind that even if you manage to fit within the line limit, overly complex mappings can still lead to performance issues. Always aim for clarity and efficiency in your mappings.
  Testing: After making changes, thoroughly test the mappings to ensure they still produce the desired results without errors.
