Thans Draksh for the screen-shot.
But what is not clear to me from the screen-shot is : " There is no header for all the dimensions except the sign data which has "BPC SignData".So, check what is the issue with the headers.
So, my suggestion is DEBUG you code, as there is a very minor mismatch with the data-types in your it_range table and the final lt_query_resut table..
Wish you luck for a proper DEBUGGING task..
Thanks & Regards,
