Loading and replacing data

[#1]

Hello,

Every week I receive files with 4 weeks of history.

First I would like to load all these files at once and each time has the common data with the previous file is replaced by that of the new and the rest is added.

Secondly I would like, by the same method to make a partial update of the file and add the new week every week.

My files have more info columns so I planned to add a column that concatenates the fields needed to create a key but I do not know if this is the right method. and I can not find how to create the control and replacement of old data when loading.

Do not hesitate if you have any questions.

Thanks for your help.
