Not able to select groups in assignment group field in cases?

[Buddy 1]

Hi,

We are facing an issues i.e., we were not able to select groups in assignment group field. 

1.We have a dictionary override for the assignment group field in parent table and it is not satisfying the condition 

2. we have a business rule that when account field changes in the case form and assignment group type is csm  then it should display the groups in assignment group field .

But, somehow the business rule is not working as expected, i.e., when account changes in case form ,it is not entering into the business rule .

How to solve this issue and make the csm type groups display in the assignment group field without enabling the dictionary override for child table.

Thanks in advance!

So what debugging have you done so far?

Is your requirement is to populate assignment group based on other fields?
