  • What is the cause and solution for SAP error message PAK045 - Package &1 begins with an invalid character (such as a digit) ?

    The SAP error message PAK045 indicates that there is an issue with the naming convention of a package in the SAP system. Specifically, the error states that the package name begins with an invalid character, such as a digit. In SAP, package names must adhere to specific naming conventions to ensure consistency and avoid conflicts.

    Cause:

    The primary cause of this error is that the package name you are trying to create or modify does not comply with the naming rules set by SAP. According to these rules:

    • Package names must start with a letter (A-Z).
    • Package names can contain letters, numbers, and underscores, but cannot start with a digit or contain special characters.

      • Right-click on the package and select the option to rename it.
      • Enter a new name that adheres to the naming conventions.
    3. Check Dependencies: If the package is already in use, ensure that renaming it does not break any dependencies or references in your development environment.

    4. Transport Requests: If the package is part of a transport request, make sure to adjust the transport request accordingly after renaming.

    5. Test: After renaming, test the package to ensure that it functions correctly and that the error message no longer appears.
