• What is the cause and solution for SAP error message /PM0/3FT_MESSAGES200 - Structure or table &1: Underscore not permitted at point 2 or 3 ?

  The SAP error message /PM0/3FT_MESSAGES200 indicates that there is an issue with the naming convention of a structure or table in your SAP system. Specifically, the error states that an underscore is not permitted at position 2 or 3 of the name. This is a common restriction in SAP naming conventions, particularly for database objects like tables and structures.
  Cause:
  
  Naming Convention Violation: In SAP, certain naming conventions must be followed for database objects. The error suggests that the name of the structure or table you are trying to create or modify contains an underscore (_) at the second or third position, which is not allowed.
  Incorrect Object Name: The object name may have been generated automatically or manually entered incorrectly, leading to this violation.
  
  Solution:
  
  Rename the Object: You need to rename the structure or table to comply with SAP's naming conventions. Ensure that the name does not have an underscore in the second or third position. For example:
  
  Instead of Z_MY_TABLE, use ZMY_TABLE or Z1_MY_TABLE.
  
  
  Check Naming Guidelines: Familiarize yourself with SAP's naming conventions for database objects. Generally, the following rules apply:
  
  Names should start with a letter (A-Z).
  The second character can be a letter or a number (0-9).
  The third character can be a letter, number, or underscore, but not an underscore if it is in the second or third position.
  Names should not exceed 30 characters.
  
  
  Adjust Code or Configuration: If the name is being referenced in code or configuration, ensure that all references are updated to reflect the new name.
  
  Related Information:
  
  SAP Naming Conventions: Review the official SAP documentation or guidelines regarding naming conventions for database objects to avoid similar issues in the future.
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary) to check the definitions of structures and tables and make necessary adjustments.
  Transport Requests: If the object is part of a transport request, ensure that the transport is updated with the new name to avoid inconsistencies across different environments.
  
  By following these steps, you should be able to resolve the error and successfully create or modify the structure or table in your SAP system.
