• What is the cause and solution for SAP error message ISSR_TP756 - Field name & in dynamic SELECT is longer than 66 characters ?

  The SAP error message ISSR_TP756 indicates that a field name used in a dynamic SELECT statement exceeds the maximum allowed length of 66 characters. This is a common issue when working with dynamic SQL in ABAP, particularly when constructing queries that involve long field names or concatenated strings.
  Cause:
  The error occurs because:
  
  In ABAP, the maximum length for field names in dynamic SQL statements is restricted to 66 characters.
  If you are trying to use a field name that is longer than this limit, the system will throw this error.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Shorten Field Names: If possible, use shorter field names in your dynamic SELECT statement. This may involve using aliases or renaming fields in your database view or table.
  
  
  Use Views: If you are working with database tables, consider creating a database view that includes only the necessary fields with shorter names. This way, you can reference the view instead of the original table.
  
  
  Refactor Dynamic SQL: If your dynamic SQL is constructed using concatenation, ensure that the resulting field names do not exceed the 66-character limit. You may need to break down the query into smaller parts or use subqueries.
  
  
  Check for Concatenation: If you are concatenating field names or using long expressions, review the logic to ensure that the final field name does not exceed the limit.
  
  
  Debugging: Use debugging tools to inspect the dynamic SQL statement being generated. This can help you identify which field name is causing the issue.
  
  
  Related Information:
  
  Dynamic SQL in ABAP: When using dynamic SQL, it is essential to be aware of the limitations and best practices to avoid runtime errors.
  Field Naming Conventions: Familiarize yourself with the naming conventions used in your organization or project to ensure that field names are kept concise.
  Performance Considerations: While refactoring your SQL, also consider the performance implications of your changes, especially if you are working with large datasets.
  
  By following these steps, you should be able to resolve the ISSR_TP756 error and ensure that your dynamic SQL statements comply with SAP's field name length restrictions.
