How to repair Table join for created ABAP query

Hi,

I have created a query in Dev- But after creating user has removed the field EKGRP from table ZMT160_EX1.

But to create query i used this field for table joins (Tables used are T001W, LFA1 and LFM1). now if i tried to test the query it is going for dump.

and i tried to change the join in SQ02 for infoset. but there also it is going for dump
