Generated Thingpredictor-[Model Name]-AnalysisThing not working programmatically with service

[Max3]

Hello,

we successfully generated a Thingpredictor-[Model Name]-AnalysisThingTemplate via the TW Analytics Manager.

Then we created a Thing from this ThingTemplate in Thingworx.

We have the following properties provided:

If we manually add a new row in the data infotable it works and analytics executes an analysis job (also it generates a key id as you can see here):

But if we programmatically try to add a new row with a thingworx service it only adds a new row without the generation of a key and analysis job:

var newRow = new Object();
newRow._Wert1 = 26;
newRow._Wert3 = 28;

me.data.AddRow(newRow);

What could cause such a behaviour?

Do we need to do some additional steps for this to work?

Thank you in advance,

Max

Hello Christophe,

I looked into the link you provided me, thank you.

But it still doesn´t seem to work for me.

I created two services AddNewRow and SetInfotable:

But it still doesn´t generate a key.

Can you give me an example how it should be done correctly?

Thank you,

Max

Hi @Max3

Here is a solution that will work, taking the problem a bit differently.

1) Create a persistent property on the thing, named, let's say trigger

2) Create the Analysis Event in Analytics Manager to trigger on DataChange event for the property trigger

3) in your original code, simply increase the value of trigger

me.data.RemoveAllRows();
var newRow = new Object();
newRow._Wert1 = 26;
newRow._Wert3 = 28;

me.data.AddRow(newRow);
me.trigger = me.trigger+1;

This works well on my side, analysis jobs are being triggered and executed.

Hope this helps

Kind regards

Hi @Max3

I have made an update to https://www.ptc.com/en/support/article?n=CS277418 with a sample code that shows how to make it work through the info table directly without using the trigger property ... both solution are equally valid.

Kind regards
