Issue with Previousmonth with blank rows

[DamienBrux]

Hi, 

I am having trouble with Previousmonth functions (or dateadd), when I compare the sales per clients. The problem arises when a client purchases in M-1 and do not purchase in M. In the lattest case there is no line in the database.

To illustrate Client Turbin has sales in Feb (30) and when I look in M-1 in March I have 0. Total line is not coherent neither.

I am not using a calendar table in this simplified example but I get to same result with a calendar table.

Thanking you in advance.
