• What is the cause and solution for SAP error message STOBJ155 - Field name & for use in DB table or view exists multiple times ?

  The SAP error message STOBJ155 indicates that there is a conflict due to a field name being used multiple times in a database table or view. This typically occurs when you are trying to create or modify a database object, and the system detects that the field name you are using is not unique within the context of the table or view.
  Cause:
  
  Duplicate Field Names: The most common cause is that the same field name has been defined more than once in the structure of the database table or view.
  Inconsistent Naming: If you are using a structure that has been copied or modified, it may inadvertently include fields with the same name.
  View Definition Issues: If you are creating a view that includes multiple tables, and those tables have fields with the same name, this can lead to ambiguity.
  
  Solution:
  
  
  Check Field Definitions: Review the definitions of the database table or view to identify any duplicate field names. You can do this by:
  
  Using transaction codes like SE11 (Data Dictionary) to view the structure of the table or view.
  Checking the field names in the ABAP Dictionary.
  
  
  
  Rename Fields: If you find duplicate field names, consider renaming them to ensure that each field has a unique name within the context of the table or view.
  
  
  Modify View Definitions: If the error arises from a view, ensure that you are using aliases for fields that have the same name in different tables. For example, you can use the AS keyword to give a unique alias to each field in the view definition.
  
  
  Recreate the Object: If the issue persists, you may need to delete and recreate the database object (table or view) after resolving the naming conflicts.
  
  
  Check for Dependencies: Ensure that there are no dependent objects that might be affected by renaming fields or modifying the structure.
