Adding dates then values to null values

[pauledrich]

Hi and thanks for the help

I have read a couple of articles on this topic and also experimented within the load script but don't seem to be able to get it quite right.

The scenario:

I have a table 'MonthTargets' taken from a QVD with the fields Location, Month, Year,Product & MthTarget from which I have generated a TargetDate Field by 'MakeDate(Year,Month) AS TargetDate' which returns a date of 01/MM/YYYY - but I want to create weekly targets based on the monthly figure.

I need to create a date between the 1st of each month and End and also add the MthTarget to each of those date fields. I have tried using the previous function from a previous post which is :-

Loadcalcs:

Load *,  

if(previous(Location)=Location,previous(TargetDate)) as PrevDate,

if(previous(Location)=Location,previous(MthTarget )) as PrevVal1;

Concatenate(MonthlyTargets)

Load Location, 

TargetDate - IterNo() as TargetDate,

PrevVal1 as MthTarget

Resident MonthlyTargets

while TargetDate - IterNo() > PrevDate

order by Location, TargetDate desc;

drop field PrevDate, PrevVal1;

This solution on looks close.

And also attempted one using Peek as described in the technical brief by Henric - 'Generating Missing Data' but end up with 14m records being added.

I would really appreciate any detailed help on where I am going wrong.

Hey Paul,

Would it be possible to attach a sample file with the tables you have and how you want the resultant table/results to look like. It will be helpful in addressing the issue.

Thanks

Continue through to year 31/12/2014

As you can see location 1 has a target on the 1st of each month - I would like to have the monthly target for each day of the month shown in a row for each date.

For this Dashboard I am using one master calendar linked to various fact tables.

Maybe like attached? Its a little cheesy solution but it might work for you from my understanding of your requirement.

Thanks

try this

I changed your Target just to check the result

Let vMinDate = num(date('01/01/2014'));

Let vMaxDate = num(date('31/12/2014'));

Calendar:

LOAD Date, num(Month(Date)) as Month, Year(Date) as Year;

Load Date(recno()+$(vMinDate)-1) as Date

Autogenerate $(vMaxDate) - $(vMinDate) +1;

Table:
