• What is the cause and solution for SAP error message 0T145 - The name &1 is not allowed for the required object ?

  The SAP error message 0T145, which states "The name &1 is not allowed for the required object," typically occurs when there is an issue with the naming convention of an object in the SAP system. This error can arise in various contexts, such as when creating or modifying objects like tables, programs, function modules, or other repository objects.
  Cause:
  
  Invalid Naming Convention: The name you are trying to use for the object does not conform to the naming conventions set by SAP. For example, certain prefixes or reserved names may not be allowed.

  Check Naming Conventions: Ensure that the name you are using adheres to SAP's naming conventions. For example, custom objects typically start with a specific prefix (like Z or Y) to distinguish them from standard SAP objects.
  Avoid Reserved Names: Make sure that the name you are trying to use is not a reserved name in SAP. You can refer to SAP documentation or community forums for a list of reserved names.
  Length Check: Verify that the name does not exceed the maximum length allowed for the object type you are creating or modifying.
