costs

[Carlaf_93]

Good morning,

I'm trying to link a cost to a specific person. I've got a type of cost and a final date until when that cost is linked.

For example the date 10/02/2020 is < of 31/07/2020 then the 70 will be linked to pippo and so on....

How can i do it? If there isn't a date it means that it still works now.

TAB1:

LOAD * inline [
COST, NAME, FINAL_DATE,
GD56YTG, pippo, 31/07/2020,
GD56YTG, teo,,
FF56YTG, gino,];

TAB2:

COST,  DATA,  VALUE,
GD56YTG,10/02/2020,70,
GD56YTG,11/06/2021,30,
GD56YTG,20/05/2021,40,
FF56YTG,20/05/2021,40
