Credit Limit Issue

Dear All,

I have a issue with credit limit, i have defined the below 3 risk and the system response as below

1) Z01(Low Risk Category) - If limit is exceeded the system gives information of the credit limit exceeded and allows to deliver

2) Z02(Medium Risk Category)- If limit is exceeded the system BLOCKS the sales order

3) Z03(High Risk Category) - If limit is exceeded then the system does not allow to save the sales order

i have a issue with Z03 ( High Risck Category ) for example if the credit limit of a customer 10000 Rupees and 95% (9500 Rupees )of the limit is consumed already

If i create a sales order without any items and save it and then in the sales order change mode i enter the material more than the avialable credit limit ( 5 %).(500 Rupees) system is allowing me to exceed the credit limit and even allowing to deliver it.

But as this customer is a high risk customer if the limit is exceeded the system should not allow to save the order

In the above case if i create the order without any line items (Material) and save it and later enter materail of any value system is allowing the order to save and letting me to even create the delivery.

Kindly advise how can i avoid the users from using this trick to exceed the credit limit even if the customer belongs to high risk category where in the order is not supposed to save when the credit limit is exceed

With Regards
