route redetermination at delivery

Hello all,

we are planning to carry out route - re determination at the delivery level based on shipping point considering the weight groups and not based on delivery type.

there is a user exit in standard SAP (EXIT_SAPL0VRF_001) that does the customer specific route re determination by data transferred from delivery header and also from sales order.

the question is whether the SAP user exit will be sufficient to carry a route re determination at delivery level by checking the shipping point or is any new Zprogram needed to satisfy the requirement.

If i need a zprogram, is it mandatory to have any special Ztables to read the shiiping point at the delivery or can the zprogram be created with no special Ztables, so that it checks the shipping point in the delivery header to carry out delivery level route redetermination.

Pl. advise.

Thanks,

Maxx
