I used the transaction SLIN and checked my program and there I am getting an errro message which says "char strings w/o text element will not be translated"
and what I am doing right now is just declared a constant c_date(50) value 'Invalid date'.
so can you please help me how to get rid of this error.
Create a text element for that text.
enter text-001 in place of 'Invalid date', double click on text-001, it will ask you to create the text ement and create.
