Hi!

First of all, Qlikview does have function MakeWeekDate. You have Year and Week, that's all you need.

MakeWeekDate(Year, Week, 0) as Date, //This gives you proper day. Monday for weekday.

If( IsNull(LineValue), 0, LineValue) as LineValue //This replaces NULL-values from data

Then

=Avg( {\$<Date = {"<=\$(=Max(Date))>=\$(=AddMonths(Date,-6)) "} >} LineValue)

This should do the trick.

Can you post an example qvw?

You can use for example a calculate dimension like =Month(YourDateField) and then apply to that chart dimension some expressions, but certainly it isn't the most appropriate solution.

First of all, you have to use a/some calendar lookup table/s to solve this type of issues.

try this,

=num(avg({\$<Year = {\$(=only(Year))}, Month = {"<=\$(=max(Month))"}>} LineSalesAmount), '\$#,##0;(\$#,##0)')

I'll describe it a bit more accurately. I've got date in format not compatible with Qlik (year & week number), but i already solved this and i wrote function which checks if date is in my chosen range or not. If it is, it writes sum of costs from that week, if not - it puts 'NaN' or 0 (none of that worked so far). So i've got table made of '-' (none value), 'NaN' (value not-interesting me at the moment) and actual numeric value. I'm very new to Qlik and i stuck at the moment of making avg of that column. And if you could tell me where i should write script to get one avg from the whole column, i'd be very glad.

Also thank you for trying to help me
