• What is the cause and solution for SAP error message AD101 - First 7 characters of name & are identical to a table ?

  The SAP error message AD101 indicates that there is a naming conflict in the system. Specifically, it means that the first seven characters of the name you are trying to use for a new object (such as a program, function module, or class) are identical to the name of an existing database table. This is a restriction in SAP to avoid confusion and potential conflicts between database tables and other objects.
  Cause:
  
  The naming convention in SAP requires that the first seven characters of the name of a new object must be unique and not match the first seven characters of any existing database table. This is to ensure that there is no ambiguity in the system when referencing objects.
  
  Solution:
  
  
  Rename the Object: The simplest solution is to choose a different name for your object that does not conflict with any existing database table names. Ensure that the first seven characters are unique.
  
  
  Check Existing Tables: Before naming your object, check the existing database tables in the system to ensure that your desired name does not conflict. You can do this by using transaction codes like SE11 (Data Dictionary) to view the list of tables.
  
  
  Use a Naming Convention: Establish a naming convention for your objects that avoids using the same prefixes as existing tables. This can help prevent future conflicts.
  
  
  Consult Documentation: If you are unsure about naming conventions or the implications of your changes, consult SAP documentation or your organization's SAP guidelines.
