• What is the cause and solution for SAP error message GU936 - The name of the target table must begin with 'Y' or 'Z' ?

  The SAP error message GU936 indicates that the name of the target table you are trying to create or use does not conform to the naming conventions set by SAP for custom objects. In SAP, custom tables must begin with either 'Y' or 'Z' to differentiate them from standard SAP tables, which helps avoid naming conflicts and ensures that custom developments are easily identifiable.
  Cause:
  
  You are attempting to create or reference a database table with a name that does not start with 'Y' or 'Z'.
  This error typically occurs during the creation of a new table in the Data Dictionary (SE11) or when trying to activate a table that has an invalid name.
  
  Solution:
  
  
  Rename the Table: If you are creating a new table, ensure that the name starts with 'Y' or 'Z'. For example, instead of naming your table CUSTOMER_DATA, you could name it ZCUSTOMER_DATA or YCUSTOMER_DATA.
  
  
  Check Existing Tables: If you are trying to reference an existing table, verify that the table name adheres to the naming conventions. If it does not, you may need to create a new table with a valid name or modify your code to use a correctly named table.
  
  
  Review Code: If the error arises from ABAP code or a program, check the code for any hardcoded table names that do not comply with the naming convention and update them accordingly.
  
  
  Consult Documentation: If you are unsure about naming conventions or need further clarification, refer to SAP documentation or guidelines regarding naming conventions for custom objects.
  
  
  Related Information:
  
  SAP Naming Conventions: SAP has specific naming conventions for various objects (tables, programs, function modules, etc.) to ensure clarity and avoid conflicts. Custom objects typically start with 'Y' or 'Z'.
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary) to create or modify tables and SE80 (Object Navigator) to manage various development objects.
  Transport Requests: If you are working in a development environment, ensure that your changes are included in a transport request for proper migration to other environments (e.g., QA, Production).
  
  By following these guidelines, you should be able to resolve the GU936 error and successfully create or manage your SAP tables.
