Hi,
I have a list that contains a Lookup column that is based on a list from a parent site. The column has been added like "Add from existing site columns". The principle is well know I guess.
My problem now is, that this particular column is no listed as "Dynamic content" when trying to modify the list entry. All other columns are listed, but not that one. I already did some Google research and found out, that these kind of columns (lookup columns from other/parent sites) are not listed and/or not accessible be default.
What I want to achieve is in theory very simple: After an item has been created/modified, a text column should be updated with values from other columns. And one of these columns is the Lookup column.
Anyone has a solution therefore or an idea how to solve that?
Any chance to retrieve the item by REST API? Result must include the value of the lookup column of course.
BR
Christoph
