I have a dddw placed in grid DW, the dddw should get the data column (short_name-eg: 'ABC') & display column (fullname) & both are string.

But in table the stored value for data column of dw is stored in lowercase (eg: abc). In such case the data column is displayed for that column instead of display column in DW because of the case sensitive mismatch ('ABC','abc').

Is this expected? 

Please provide some clarification on this.

Thanks in advance.
