When your business starts to build lots of sheets (as we have) the issue of data integrity comes into play. That is if you have lots sheets with names, or activities you can now put them into one sheet and reference to them BUT whenever you build a form and want to restrict the user selection to the defaults in the drop down list, these have to be are entered at the column level and cannot reference your master reference.
Tell me if I am wrong!. This needs to be resolved to ensure there is not madness in updating multiple forms selections manually across multiple sheets.....
Then IF you could actually refer to a column(s) of master data in a form AND you could then reference an EXISTING row to perform an update on it (from a FORM or a update request) we would be in a great place.
Any ideas out there, is this on the never never enhancement list ?
