Why is there a parameter interaction across section? And ho

sindrew — Tue, 19 Feb 2019 14:53:46 GMT

I have a report with multiple sections, and all sections are filtered by a date filter (single select list box). This list box sets a parameter which is then used in a calculated item say

IF ('StartDate'N <= 'MyParameter'p)
Return 1
ELSE 0

This works in Section 1. The parameter filters the data and in I can see a parameter interaction when I view all interactions for that section.

However, I want to use the same category fiter in a different section to set a different parameter. Again, a single select list box, with the same category. A new parameter, and a new calculated item (with the same calculation).

IF ('StartDate'N <= 'MyParameter2'p)
RETURN 1
ELSE 0

Now this doesn't compute the same numbers as in section 1. When I view the interactions I can see a parameter interaction from section 1 to objects in my current sections. Why is there a parameter action from my section "Oversikt" to my vertical container and pivot table? How can I remove it? Deleting it from the interaction screen does not help. There is only one datasource in the report.

Hi!

Where have you placed the list box?

If you place it in the report query or section query you it will automaticallye filter your data.

If you place it on the "report canvas" instead no automatic filtering will occur, only the parameter filter.

I use "help tables" when I want to place filters in the report/section query area, so that they won't filter the data.

Which version of VA are you using - 7.4?

It's on the canvas. The report should filter by the parameter as it accumulates data - there is no direct interaction between that list box and other items e.g tables or graphs, besides that a calculated item with the parameter is placed in a table. There are other listboxes that filters that remaining data, and they work as expected.

What I don't understand is, why does a parameter from one section used in one calculated item affect a different section with a different parameter and calculated item? The category which I filter by is the same.

The listbox contains dates, and the parameter is also a date, if it matters.

It's VA 7.4 - There's always next version.

Hi!

Really strange.

I have created a report with two sections.

I each section i have one list box and one table, on the canvas 🙂

I have created two date parameters each connected to one list box.

I have created two calculated measures one for each table:

IF ( date <= 'dat1'p )
RETURN 1
ELSE 0

I use the same data source for all objects.

My report works as expected and the only interaction I get is two parameter interactions between each listbox and the table where the calculated measure is within.

The list boxes works totally separated for me....

There must be something I (or you :)) do in another way.

It was me

In my calculated measure I used another and different calculated measure that used my parameter from the list box in first section. This affected all other calculations in other sections.

Thanks for spending some time on the issue.
