Link between credit management and payment terms?

Hi All,

Using credit management i am cleared the two open items posted for the SO using f-28.

Then when i create the same Sale order its giving standard error

" credit : Maximum percentage for open items exceeded"

I think that in configuration of OVA8 its giving problem :

Can you pl explain on link between credit management and payment terms???

Urgent...
