We have sharepoint 2010 and I have 2 list that are linked via a lookup, one contains customer details and the other there order details and we lookup on the order list for the customer details.
We are trying to find a solution so that if the user is entering the order but the customer does not exist the user can add the customer without leaving this current new list item.
I tried adding the SPService SPlookupAddNew function which add a new button and launches a new page and they can enter the details but when they come back the order list is wiped and they must start again.
I'm assuming that I'm not the first to have this issue, How do you guys handle this problem of adding new items to a secondary list?
