problem with linktable

[souadouert]

Good morning ,

I have a link-table table of realization of the product contains the market, segement, description ,agence ... also the date of realization is monthly ie the cumulative realization (file February -contains the total realization of January + February)

And I have the objective of each  product semi-annual per agence  , I want to display for example production and objectif of each product,

The problem is the date of the realization has a date but the objective without date, when i selected date in selection objective is null
