Home > Transforms Nodes > Filter Columns > Join > Edit Join Node > Resolve Dialog
When a Data Source is disconnected from a join, all the join specifications for that node are retained and are marked them as invalid. Before you execute the Join node, you must resolve the issues.This dialog provides two ways to resolve the join issues:
Remove removes all of the invalid entries from all specifications (Apply and Data)
Resolve displays a grid that allows you to associate an unassigned node with a missing node. The missing nodes are listed in the grid, and an action is suggested.
