How to add _BATCH_LAST_RUN_ to the dataflow built with SQL
I am trying to find a way to add BATCH_LAST_RUN column to one of the datasets I have created. I found A way - s to change replace method to append. In this particular dataset, I am grabbing the last 7 days' worth of data, so I need to replace the whole dataset on each run.
Is there any way to add this column with replace method fro SQL dataflow?
