User exit for controling header and item division

Question

Hi all,
Currently there is restriction in sales document for header division and item division i.e. if header division is 10 then it is not accepting the products of division 20, 30, 40, 50 at item level.
If the restriction is removed then it will allow products of all division in a sales document irrespective of header division (if the customer is extended for all the sales area).
But we would like to allow products of division 10, 20 and 30 in one sales document if header division is 10 or 20 or 30.
How can it possible? Can it be possible through user exit? Any standard user exit is available or we would have to develop one?
Please guide me how to go about.

Thanks Navaneetha Krishnan,
1. Please give some more inputs on Cross Division,
2. To enable to incorporate other division than header at a item level is ok, but restriction on some division at item level is what i want to know, weather through user exit and which user exit? or I will have to create user define User Exit?
e.g. customer 1234 is created for all the sales area
Sales areas are : 1000  10  10
                          1000  10  20
                          1000  10  30
                          1000  10  40
                          1000  10  50
now in ZOR Sales document(where there is no restriction of item division) if I enter sales area 1000  10  10 at header it will allow the product of all division.
but i want if i put at header 1000  10  10 then it should allow the products of division 10 and 20 only and not to allow products of divsion 30,40,50 in one sales document
similar if i put sales area 1000  10  30 at header level it should allow me to enter products of division 30,40,50 and should not allow products 10, 20 in one sales docuemnt
I think this is more clear. request you all to provide details ASAP
