Hi @ScottShearer ,
I have created a button in the list which will trigger the flow.
eg: I have a list A, it has 5 items , and 3 managed metadata columns and one column is a button flow on clicking of that button the flow will trigger and it will take all the 3 values of managed meta data column with itself from the list.
Now I have document library say B, it has 100 documents files and same 3 managed metadata columns as in the list A .
Now what the flow should do it should iterate through all the document files and update there columns with the values which it has taken from List A.
Note: Columns are managed metadata column that means the values are selected from the term store.
I think we have to use "send Http " action item in flow to update the values in library B.
Let me know if you want some more elaboration on this.
Thanks for your help!
