  The SAP error message /SAPSLL/CORE_CLSMD019 indicates that there is an issue with a numbering scheme in the SAP system. Specifically, the error states that the numbering scheme must not start with an underscore (_). This error typically arises in the context of SAP Logistics or SAP Global Trade Services (GTS) when defining or configuring numbering schemes for various objects.
  Cause:
  The primary cause of this error is that the numbering scheme you are trying to define or use begins with an underscore. In SAP, certain naming conventions are enforced, and starting a naming scheme with an underscore is not allowed. This restriction is in place to maintain consistency and avoid conflicts with system-defined identifiers.
  Solution:
  To resolve this error, you need to modify the numbering scheme so that it does not start with an underscore. Here are the steps you can take:
  
  
  Identify the Numbering Scheme: Determine which numbering scheme is causing the error. This could be in a configuration setting or a custom development.
  
  
  Modify the Naming Convention:
  
  Go to the relevant configuration area in SAP where the numbering scheme is defined.
  Change the name of the numbering scheme to ensure it does not start with an underscore. For example, if your numbering scheme is _MyScheme, change it to MyScheme or My_Scheme.
  
  
  
  Save Changes: After making the necessary changes, save the configuration.
  
  
  Test the Changes: Perform a test to ensure that the error no longer occurs and that the numbering scheme works as intended.
