Hi,

You can have an idea by going to Sales Header Table and find the function to get and set work description.

procedure SetWorkDescription(NewWorkDescription: Text) var OutStream: OutStream; begin Clear("Work Description"); "Work Description".CreateOutStream(OutStream, TEXTENCODING::UTF8); OutStream.WriteText(NewWorkDescription); Modify(); end; procedure GetWorkDescription() WorkDescription: Text var TypeHelper: Codeunit "Type Helper"; InStream: InStream; begin CalcFields("Work Description"); "Work Description".CreateInStream(InStream, TEXTENCODING::UTF8); exit(TypeHelper.TryReadAsTextWithSepAndFieldErrMsg(InStream, TypeHelper.LFSeparator(), FieldName("Work Description"))); end;

EXIT;

FileName := Filemgm.BLOBImportWithFilter(TempBlob, 'Upload File', '', 'All Files (*.*)|*.HTML*', '.HTML');

ELSE BEGIN
Rec.MODIFY(TRUE);
