+===== Iterate table =====
+This action is similar to [[transformations:iterate|Iterate]] action, but allows passing a table to an iterated project. The "Iterate table" action has two inputs:
+. The output of the previous action
+. The external table it references
+The action works as follows: it takes a dataset from another table (2), passes it to the called module or project, and runs it as many times as there are rows in its input dataset (1).
+The iterated project should use [[transformations:input|Input]] transformation in order to receive the table.
+This action allows significantly increasing performance in cases when iterated project had to operate with the same dataset in each iteration.
