• What is the cause and solution for SAP error message DMCLG619 - Export parameter must not be deleted ?

  The SAP error message DMCLG619, which states "Export parameter must not be deleted," typically occurs in the context of ABAP programming, particularly when dealing with function modules or methods that have defined export parameters. This error indicates that there is an attempt to delete or modify an export parameter that is expected to be present in the function module or method signature.
