I am trying to merge df2 on df1 by group, category, date (date is a column) so that my output would look like this:
I omitted the values from df2 of sales_1 & sales_2 in my desired output example, but those rows should be filled with the corresponding group and category values from df2.

So that sales_1 & sales_2 are merged on group & category and are on the same date column. The total_x from df2 can be ignored as it can be calculated from the fields.
The total_values are not used in merge, only the ones after it.
What I've tried:
df1.reset_index().merge(df2.reset_index(), left_on=['group', 'category'], right_on=['group', 'category'])
Which throws a warning:
UserWarning: merging between different levels can give an unintended result (2 levels on the left,1 on the right)
And is not how I expect it to merge. How could I achieve my desired output?
Using
df = df1.merge(df2.unstack(), left_index=True, right_index=True)
Produces:
Is it then just reordering of columns as I want to have a unique date and 4 columns for it? Or it might be that one date has 00:00:00 to it?
