missing values to build an continue trend

[#1]

hello,

i explain my problem...  i ve some lines which represent the mouvement of my stock for an article and an site..

In this line i ve the information of the values and the quantity of my stock for the article and the site..and for the date of the movement...

So if i don t have an movement i don't have the information of the value of my stock....

Or the direction wants to have an  trend for every day...

So i ve put the information missing (quantity and Value) of my stock into new lines  for every day and every couple (article/Site) in the script...

It looks goods fpr some months but the script stop or put too many time for more than 6 month of data.... and the final application are too heavy...

Is there any other solution to solve this problem maybe with an some set analysis?
