Message type: E = Error
Message class: PG - Error Messages for Master Data Programs
Message number: 449
Message text: Note: Conversion class &1 must be encoded manually.
The program PM01 generates only the empty conversion class with the
correct interface.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
The conversion class converts the data saved in the database (PS
structure) into the data displayed on the screen (screen structure) and
vice versa. The conversions are infotype-specific and cannot be
generated. For information about programming, see the document "UI
Programming Guidelines for Infotypes" in the Knowledge Warehouse. (See
also the application help (PM01).)
