Hi Guys I am trying to create a table in Qlikview that shows me sales starting from current week (Week 11) and works back Week 10 Week 9 etc to week 52 previous year. I can do this by creating individual expressions but this would be extremely time consuming. I have been trying to write an expression but having no joy. Is there a way i can create these columns within the table using calculated dimension where i can write a formula, something like:
= sum({=$(=Week(today()-52))<=$(=Week(today()))"}>} QTY)
That would create each week and show the qty of sales.
I would use a numeric representation in the script:
create a field in your calendar: year(date)+Num(Week(MyDate), '00') as yearweek
then you can create a variable vStartWeek: =(max(Year)-1)&52
then your expression will be = sum({<yearweek={">=$(vStartWeek)"}>} QTY)
no need for <=Week(today()) unless you already sold something in the future ;D

I am attempting to create a gantt chart in Power Bi using the matrix view, and the end user wants it to have year, quarter, and month. The year and quarter columns are fine, but the month columns are out of order, and I cannot seem to figure out how to put them in order. My calendar table and everything in it are created using dax.
So far, I haven't really tried anything. I am assuming Power Bi is not recognizing them as months in a date table and that is why it is not sorting them accordingly, but alphabetically by quarter and year.
You need a sort by column.
You can read how to create one here.

Please help. I don't understand why I have 2 similar data models and one works but the other does not.
I have a fact table with a Calendar Key and data as granular by day by location. I have a calendar dimension table with a Calendar key, each individual date, and month/fiscal year definitions.
Measures are Rev = SUM(FactTable[RevColumn]) then Rev PY = CALCULATE([Rev], DATEADD(CalendarTable[Day_Date], -1, YEAR))
Model 1 in Power BI, when I apply date filters, Rev calculates the total revenue & Rev PY calculates last year's rev for same range. Even if I select all dates that are YTD (which is tedious)
Model 2 in Excel 2016 Power Query, when I apply a year filter, Rev calculates total revenue for YTD in Fiscal Year & Rev PY is blank.
I don't understand what is different and why it would even fail in the first place. Calculate is supposed to override the filter context of the current filters right?
Also: the only "Date" type columns are located in the calendar table so it's not possible for me to select the wrong table.
I ultimately had to ask a professor on Udemy.com. The solution is to mark you calendar dimension table as a "Date Table." Since I'm combining the 2 tables on a whole number field, the time intelligence functions only work when filtering with date columns.
By marking the Calendar table as the Date table, the time intelligence functions know to use any attributes from that table to filter down the date ranges and get and display the appropriate answer.
In Power Pivot view, click the "Design" ribbon, then click the "Date Table" button and the "Set Default" button after that.
This resolved all issues I had.
Crosstab report works 99%.
About 20 rows, all but one are ok.
5 columns - Company Division.
The rows are things like cost, revenue, revenue 2, etc.
All the rows that work have three attributes I'm using to select them:
Fiscal Year
Period
Solution.
The problem is there is table that lists an YTD rate for each period. This table is not Division Specific; it's company wide.
All the tables are linked to the accounting period table that has fiscal year and period. So the overall query limits data to fiscal year (?pFiscalYear?) and period <= ?pPeriod?, based on prompt page results.
The source table has this:
FY_CD PD_NO ACT_CURR_RT ACT_YTD_RT
2018 1 0.36121715 0.36121715
2018 2 0.32471476 0.34255512
2018 3 0.25240906 0.31210183
2018 4 0.33154745 0.31925874
Note the YTD rate is not an average of any of the other numbers.
When I select the ACT_YTD_RT, as a row, I want the ACT_YTD_RT that matches the selected period.
What I get is the average if I set the aggregation to average or the lowest if I set it to other aggregations. So sometimes, it looks right (if I run for period 1,2,3, as the rate kept falling), and sometimes it's wrong (period 4
returns .3121 instead of .3192).
I've tried a number of different methods and can generate garbage data (totals, min, max, average) and crossjoins but can't figure out how to get the value I'm looking for.
I want YTD_RT where fiscal year =?pFiscal? and period = ?pPeriod?.
I tried a straight if then clause:
if (sourcetable.fiscalYear = ?pFiscalYear?) and (sourcetable.Period = ?pPeriod?) then (ACT_YTD_RT)
but I get an error like this:
'ACT_YTD_RT' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. (SQLSTATE=42000, SQLERRORCODE=8120)
If I create another query that generates the right response and try to include it, I get a crossjoin error that the query I'm referencing is trying to crossjoin several other items in the crosstab query.
A union doesn't work (different number of columns).
Not sure how a join would work since the division doesn't exist in the rate table.
I maybe could create a view in the database that did a crossjoin of the division table and the rate table, add that to the framework and then I wouldn't have a crossjoin since the solution would be in the rate "table" (really view), but that seems wrong somehow.
If I could just write a freaking parameterized query direct to the database I'd be done. But in Cognos 11 crosstabs I can't find a place for a SQL query object. And that shouldn't be necessary.
I've spent hours and hours chasing this in circles.
Anybody have any ideas?
Thanks

So the earlier problem was that this:
if (sourcetable.fiscalYear = ?pFiscalYear?) and (sourcetable.Period = ?pPeriod?) then (ACT_YTD_RT)
Generated an error like this:
'ACT_YTD_RT' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. (SQLSTATE=42000, SQLERRORCODE=8120)
To fix the above, I had to add a cross join of the division table and the rate table as a view in the database. Then add that to the framework. Then build the data item this way:
total (
if (sourcetable.fiscalYear = ?pFiscalYear?) and (sourcetable.Period = ?pPeriod?) then (ACT_YTD_RT)
)
And now the "total" provides the missing group by. And the crossjoin in the database provides the division information so the crosstab is happy.
I still think there should have been an easier way to do this, but I have a functioning hammer at the moment.
I'm trying to put together an attendance report for a school that tracks student attendance codes for that student for every day on the calendar month in a DynamicsCRM system being used as a managed service (that is to say, I build queries using FetchXML and cannot use SQL). The format for the report requires that a column for every day in the month be listed for the report. My student table that tracks this attendance however only contains records for days where an attendance value is recorded, and I do not have an object available that can return every day in a month for me.
I am looking for a solution other than hardcoding 31 columns and using conditionals to control the display of the last three day columns. Ideally, I'd like a conditional in my matrix column grouping that would look at the date value for the previously generated column and determine if the next date record from my resultset is sequentially the next day of that month, and if not, create the next sequential date, move to the next column and perform the check again until it is true. Is there a way I can do this, or another means to accomplish my goal that does not involve hard-coding day columns into a table or matrix? Right now, I have nothing; I can barely imagine how I think this should look.
What I did to solve the same issue has been to create a scheduled process each day to create a record and deactivate it.
I have then been able to distinguish actual records (the active ones) from these 'placeholders' (inactive ones) in my querying.
I have a report that takes sales data from a few tables. I want to add a field that will divide the total sales for the given month by the total number of business days in that same month. Is there a way I can calculate that in an expression? Do I need to create a new table in the database specifically for months and their number of business days? How should I go about this?
Thank you
Intuitively, I would say that you need a simple function and a table.
The table is to host the exceptions like Independence day, labor day, etc.
The function will get two parameters: Month and Year (I'm not providing any sample code since you haven't specified which language you are using).
It will then build a date as yyyy-mm-01 (meaning, first day of the month). If will then loop from 2 to 31 and:
Create a new date by adding the index of the loop to the initial date,
Check if the resulting date is still within the month,
Check if it is a working or not working day (e.g. Sunday),
Check if it is found within the table of exceptions.
If the created date passes all the above tests, you add 1 to the counter.
Though it might look complex, it is not and it will provide you the correct answer regardless of the month (e.g. Feb.) and the year (leap or not).
