Credit Management_OVA8_Open Delivery Value Not Check

Dear Experts,

We are using automatic credit limit (Static), our issue is when Credit Limit less then receivable system not check delivery value even total delivery value more the receivable. Please go through below scenario & give your comments.

Credit Limit 1500

Receivables 1000

Delivery value 1000

in this case we want to restrict to post goods issue of delivery due to delivery value more then credit limit value by Rs .500/- we have already tick on open delivery in OVA8
