I have three lists A, B & C.
List A have the lookup columns and existing List Template.
List A have two lookup columns,which are pointing to List B & C's columns.
- How to edit the column in List A and change the lookup Target / source in SharePoint 2010?
- Is it possible?
You have to delete the existing lookup list column and you have to create new lookup column.
I haven't tried it yet, but I have the same requirement, so I'll be doing it soon. https://www.ilikesharepoint.de/2013/12/sharepoint-repair-lookup-columns-which-are-not-connected-to-a-list/
