Concatenation problem

[#1]

Hello

Monthly i receive a Xls File with a lot of information abour costomers ,  so the goal is to set up a pivot table or reference table to add juste the new entries , to have a message like that : for example ( for octobre 4 customers  are be add , for septembre 5 cust are been added ...)

for this

I use a concatenation of tables + qvd records

1st stage: I load my table reference

2nd stage: a month later, I reload the second example I have 2 new customers

3rd stage: a month later, I reload the table I get and I realize that I have 4 new customers , basically, he can not manage to save the last value, he  reload and show me all news entries

Someone have a idea to solve my problem Thank U
