Import values from previous period into current period
I am trying to build an import which should take the values from a month to the next one, in order to create a baseline the user would then modify as he pleases. Once he's done so, he should then import the new values into the next months.
The import seems to work, however, it deletes the value from the previous month. So for instance, it takes the value from jan 22 to feb 22, but then it deletes the value from jan 22.
How can I fix this?
Here's how I have built the import:
and here is the module (this one time I did not use a view for the import):
Thanks in advance,
