Remove all columns of a particular type except one

[Anonymous]

Question:
I am trying to remove all columns of a particular type with the exception of 1. I already know how to dynamically remove all the columns of a type, but i cant figure out how to exclude one of them. So in other words, remove all columns of type table or record except TRANSACTION_LINES.

Table.RemoveColumns(TRANSACTIONS_Table, Table.ColumnsOfType(TRANSACTIONS_Table, {type record, type table}))

This is what im using for the removal all columns of those types, just need to figure out how to not remove TRANSACTION_LINES which is a type of table.

I know im close but im totally stumped.

Hello @Anonymous 

try this

Table.RemoveColumns(TRANSACTIONS_Table, List.Difference(Table.ColumnsOfType(TRANSACTIONS_Table, {type record, type table}),{"TRANSACTION_LINES"}))
