in our company we want to develop Vendor Registration process.Suppose a computer is supplied by 5 dealers at different addresses and out of these 3 dealers have registered in the vendor database.Next time when we float an inquiry for computer the name of only the 3 dealers should be copied into the purchase inquiry so that only they will be required to quote thus speeding up the purchase cycle time.
Please give some idea about how to achieve this i.e maintaining the vendor database and the items supplied by them. and to bring it into the purchase inquiry

You can always zoom to vendor master and filter the record as per your criteria in after.read. If you want to generate the list by using create.listbox() and can read the supplier master to generate this list dynamically. But I guess this will take some time as system will have to generate this list on fly. But you can give a try.
