How to call Data Adapter in a Business Rule?

I'm working with a BI Viewer and working out how to sort the dates within the Time data set. Is their an API that allows to call the data adapter used within a dashboard?

Currently the dates on the X-Axis are disorganized and are being sorted based on M1x, M2x which causes October (M10) to precede after January (M1).

Hi @MarkHoughton 

Apologies that I wasn't able to update this post earlier. But I was able to find a fix to this date issue - 

You would need to switch this to TRUE

Now go back to your BI-Viewer. This should add "Start" and "End" Date data-items. Drag it to your argument pane and that should fix the dates on the axis. Hope this helps you save development time.

Yes you can call a Data Adapter using this method:
brapi.Dashboards.Process.GetAdoDataSetForAdapter

This is a snippet from which you should be able to adapt for your purposes, so you can get time-sorted pivot tables/pivot grids.

 

'----------------------------------------
Dim dctVars As New Dictionary(Of String,String)
dctVars.Add("Cube","MyCubeName")
dctVars.Add("Entity","E1001")
dctVars.Add("SomeOtherParamX","XXXX")
dctVars.Add("SomeOtherParamY","YYYY")

Using ds As DataSet = brapi.Dashboards.Process.GetAdoDataSetForAdapter(si, False, "AdapterName","ResultsTable", dctVars)
If ds.Tables.Count> 0 Then ' -- If there are >0 tables in the results
Using dt As DataTable = ds.Tables(0).Copy()

For Each dr As DataRow In dt.Rows
Dim strTime As String = dr("Time").ToString()
If strTime.Length = 6 Then
' convert e.g. 2022M1 to 2022M01
strTime = strTime.Substring(0,5) & "0" & strTime.Substring(5,1)
dr("Time") = strTime
End If
Next

Return dt ' --- return this modified table to the BI Analytics component

End Using
End If
End Using

Hi @ChrisLoran 

Very helpful post.

What is the purpose of  dctVars?

Dim dctVars As New Dictionary(Of String,String)
dctVars.Add("Cube","MyCubeName")
dctVars.Add("Entity","E1001")
dctVars.Add("SomeOtherParamX","XXXX")
dctVars.Add("SomeOtherParamY","YYYY")

 

and how do you reference this rule within Dashboard BI component?

To pass-in any optional parameters to the data adapter.

Hi @ChrisLoran 

I am also interested in finding out how this is implemented within a data-adapter that is referencing a Cubeview to supply the data to the BIV-chart. My charts are either sorted on the x-axis as alphabetised Apr,Aug,Dec etc or in the M1,M10,M11 format as described by @Mustafa_A . How do we call this code when data is in a CubeView ? In the CubeView the data is sorted as expected in the Jan,Feb,Mch or P01,P02,P03 sequence, so I cannot see how calling this from within the CubeView will alter the data.  If it requires it to be a Method query, then what is that syntax structure for including this and embedding the CubeView or wil the data for the BIViewer component need to be configured some other way ?  Or is the date field as a Hdr description in the BIViewer edited via a calculated field method ?

Hi Mustafa,

I appreciate the extra information in your solution. Thank you

You could use the FDX queries to extract the Cube View data directly into a DataTable, then iterate through the rows and replacing time names with sortable names, e.g. 2022M5 --> 2022M05.
The FDX would not require a separate Data Adapter to retrieve the cube view information.

Here is a sample on how to fake the period names so the BI Viewer components will sort them in the correct order (rename the .txt to .xml before importing)

To call this from a Data Adapter, here is a sample query:
{SortCubeViewTest}{GetCubeViewData}{CubeViewName=[PPE],|!WfProfile_Assigned_Entities!|}

Snippet

Case Is = DashboardDataSetFunctionType.GetDataSetNames
Dim names As New List(Of String)()
names.Add("CubeViewTest")
Return names

Case Is = DashboardDataSetFunctionType.GetDataSet
'-- {SortCubeViewTest}{GetCubeViewData}{CubeViewName=[cube view name]}
If args.DataSetName.XFEqualsIgnoreCase("GetCubeViewData") Then

Dim strCVName As String = args.NameValuePairs("CubeViewName")
Dim nvbParams As New NameValueFormatBuilder(String.Empty, args.CustomSubstVars, False)

Dim dtResults As DataTable = brapi.Import.Data.FdxExecuteCubeView(si, strCVName, _
"HoustonEntities", "E#Houston", _
"Scenarios", "S#Actual", _
"T#2018M1", nvbParams, False, True, String.Empty,2, False)
If Not (dtResults Is Nothing) Then
For Each dr In dtResults.Rows
Dim strTime As String = dr("Time").ToString()
If strTime.Length = 6 AndAlso strTime(4)="M"c Then
strTime = strTime.Substring(0,5) & "0" & strTime.Substring(5,1)
dr("Time") = strTime
End If
Next
End If
Return dtResults

End If
End Select



Result: notice the Time column is now been 'faked' into a sortable name.
If you want to make it like "Jan","Feb","Mar" then the BI Anaytics components will probably sort it alphabetically and mess up the order again.  You would need to show both columns, one to force the sort order, and another for the descriptive part.
