Replacing # with blank space at the report level

BW gurus

I need to replace # with blank space at the query level.

VB macro we can do at the workbook level. Do any one know can we assing workbook in WAD.

I am assigning that query to the table in WAD.

As per my requirement if i do it with ABAP class at the WAD level or using java script is not useful.

Please let me know is there any possibility to do this at query level.

Thanks and regards
