prevent SO while credit limit still in approval process

Hi All,

Can we prevent SO being inputted while credit limits still in approval processing?

Sample case :

We have a new Customer AAA with credit limit $500.

First, we create customer master for AAA and input $500 for its credit limit. Then this data goes to workflow process for approval.

During the approval processing, can JDE give a hard error when user try to input SO with customer code AAA?

What setting should I apply? Or is there any workaround for my requirement above? We use EnterpriseOne 9.1.

BR,

Kinan
