Credit Analyst is not getting assigned to the Manual Credit Application Request

Hi,

I don't any assignment rule in Credit Management.

For one of the customer, I have assigned the value for Credit Classification as well as Credit Analyst at Account level.

When I create manually a credit application request to increase the credit limit, case folder is getting created; but workflow background process is not assigning the credit analyst.

I raised SR, but no appropriate answer.

Need help.

Thanks,

Senthil
