I'm installing a custom feature into a site collection. The feature will allow the creation of a list (list A) that gets its column data from an external webservice. The Actions menu will have a menu item that will provide an update
to all the data in the list.
I want to create List B in the same site. List B will have the same columns as List A, but will have additional columns. I need to figure out if it is possible for List B to pull that common column data from List A. I thought I could
use a workflow action on the creation of each item in List B to go get the data from List A columns, but that leaves the problem of updating the column data in List B when List A is updated.
Does anyone know of a way I can make this happen or another approach I could take?
There are no mistakes; every result tells you something of value about what your are trying to accomplish.
