• What is the cause and solution for SAP error message TXX126 - Program name must start with the letter 'Z' or 'Y' ?

  The SAP error message TXX126 indicates that the program name you are trying to create or use does not conform to the naming conventions set by SAP. Specifically, in SAP systems, custom programs must start with the letters 'Z' or 'Y' to differentiate them from standard SAP programs. This is a common practice to avoid conflicts and ensure that custom developments are easily identifiable.
  Cause:
  
  The program name you are attempting to use starts with a letter other than 'Z' or 'Y'.
  This restriction is in place to maintain a clear distinction between standard SAP objects and custom objects.
  
  Solution:
  
  
  Rename the Program: If you are creating a new program, ensure that the name starts with 'Z' or 'Y'. For example, instead of naming your program MY_PROGRAM, you could name it ZMY_PROGRAM or YMY_PROGRAM.
  
  
  Check Existing Programs: If you are trying to execute or modify an existing program, verify that the program name adheres to the naming convention. If it does not, you may need to create a new program with a valid name.
  
  
  Consult Documentation: If you are unsure about naming conventions or need further clarification, refer to SAP documentation or guidelines provided by your organization regarding custom developments.
  
  
  Related Information:
  
  SAP Naming Conventions: SAP has specific naming conventions for various objects (like programs, function modules, classes, etc.) to ensure clarity and avoid conflicts. Custom objects typically start with 'Z' or 'Y'.
  Transport Requests: When transporting custom programs, ensure that they are correctly named to avoid issues during the transport process.
  Development Guidelines: Follow your organization's development guidelines for creating and naming custom programs to ensure consistency and maintainability.
