• What is the cause and solution for SAP error message M2119 - Field catalog lies in SAP name range ?

  The SAP error message M2119, which states "Field catalog lies in SAP name range," typically occurs when you are trying to use a field catalog in a report or a program that includes fields that are reserved for SAP's internal use. This can happen when you are trying to define a field catalog for an ALV (ABAP List Viewer) report or similar functionality.
  Cause:
  The error is caused by the use of field names that are within the SAP namespace (which typically includes names starting with certain prefixes or reserved names). SAP has specific naming conventions and reserved names that should not be used in custom developments to avoid conflicts with standard SAP objects.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Names: Review the field names you are using in your field catalog. Ensure that none of the field names are reserved by SAP. You can refer to the SAP documentation or naming conventions to identify reserved names.
  
  
  Rename Fields: If you find that you are using a reserved field name, rename it to something that does not conflict with SAP's naming conventions. Use a prefix that is unique to your development (e.g., Z or Y).
  
  
  Modify Field Catalog: Update your field catalog definition to use the new field names. Ensure that the field catalog is correctly defined and does not include any SAP-reserved names.
  
  
  Test the Report: After making the changes, test your report or program again to ensure that the error is resolved.
