I have configured static credit management at sales order level with reaction as error (D maintained in ova8).
For some of the customers it is working fine but for some customers even though the credit limit is crossed system saving sales order.
I have checked all the configuration every thing is fine like.
OB45, OB38, OVA8,V/08,OVAK all the configuration is in place.
Ypdate group 12 in OB45.
Can somebody explain why this issue arises.
