webi merge problem

Hi,

we are trying 2 merge 2 dimension objects , and we created one detail object if we use detail object in rep1 it is showing blank value instead of value.

ex:

rep1 :

a/c no  

123         

145          

rep2 :

emp no    a/c name

123          aaa

145          bb

146          cc

we merged emp no & a/c no and created detail object for a/c name.

final rep

a/c no a.cname

123     -

145    -

we need to get a/c name in final rep.

Thanks.
