I have a question about querying a data model using the CDF SDK.In the Cognite SDK docs there is an example for retrieving actors in a movie (https://cognite-sdk-python.readthedocs-hosted.com/en/latest/data_modeling.html#query-instances) from the following data model: But if we would change this to finding which pumps belongs to a given facility from this data model (picture below), using a bi directional relationship between facility and pump, what changes must be made to the example from the sdk docs for this to work?  

I want to create subflows after output from first function. As number of task is not fixed, curious if we can use dynamic task within workflows.Can we do it via SDK, WorkflowTask(               external_id="subtask1",               parameters=DynamicTaskParameters(                  "tasks" = "${task1.output.tasks}",               ),               depends_on = ["task1"])Is there example how task will be created and get the input from function ? I assume ‘tasks’ key needs to be send from previous function. Example will be appreciated 

I have created a calculation on charts and also created a schedule for it to run periodically. All is good so far. What I want to do now is to edit that schedule but can’t seem to be able to do that.This is a screenshot of the page where I am hoping to be able to access my schedule from. There is no ellipsis for me to click on like there is on the top calculation in the listAlso, if I open the calculation I see this. For a new calculation, the “Running on schedule” button is “Save and schedule”. For existing schedules, though, only see the “Running on schedule” and nothing happens when you click on it.So, my question is this: is there any way to edit an existing schedule?

Hi,Could you advise me on how to fix the following error popped up from Microsoft when I get a new access token through the “Authentication” tab in Cognite API collection?AADSTS70011: The provided request must include a 'scope' input parameter. The provided value for the input parameter 'scope' is not valid. The scope {{baseURL}}/.default is not valid. The scope format is invalid. Scope must be in a valid URI form <https://example/scope> or a valid Guid <guid/scope>. I’m taking the course “Set up postman using OpenID connect” (https://lab.cognite.com/understanding-open-industrial-data/1328002)Here is my Postman setting.AuthorizationVariables 

Hello, I would like to know what is the best way to plot two variables in a XxY chart instead of stacking them. For example: I have “variable A” and I want it on Y axis and “variable B” on X axis instead of timestamp. Is it possible to do it using Charts, Canvas or should I do it on Power BI? 

Is there a tool for planning an schedulling  scaffolds ?

Is there any way to send data to cdf from blob storage using azure data factory?

I am trying to register for Cognite Data Engineer course but not able to do that because it is asking me to purchase that course with credits. Can you please help me on how to get that credits?

Hi guys, Could you please help me find out why it still shows empty time series even though I have insert data points? I am able to list the data points in “my_ts1” time series with API but I can’t view them in chart.How can I view the time series data in chart? Thanks a lot!

Dear Community,How do we transform or create transformation of SQL Table data with some time series values in to Timeseries Tags In CDF?Sample Data:index   datetime                   CO2      H2O                                                         0   2019-05-07 01:00:00+00:00     50.5     25.0 1   2019-05-07 02:00:00+00:00     55.0     27.7  All we need is 2 tags CO2 & H2O with 2 data points (TS) in a dataset. I can run each tag under separate transformation.Please help with SQL query to do in Transformation .

Hello everyone,I created a calculated timeseries based on an existing one and everything went well, except that the calculated timeseries does not have a linked asset. As a result, when I am looking at the asset on data fusion this calculation does not show up. Did I miss something? Is there a way to link this calculated time series to the asset that I want?Thank you. 

Hello, I am working at HubOcean as a backend engineer and I need to access the logs for the API calls we make to CDF. Is there are procedure we can follow to get the logs?

Can Cognite Write back to the controller? Or in other words, is it just an open loop solution or can be integrated to work as closed loop system ?

Hi.It would be useful to access metadata from time series in Grafana. Some of our time series contain simple integers 0, 1, 2..,  and the meaning of each value is a string described in a metadata field set on the time series. Could this functionality be added to the CDF Grafana data source? Or is there a way to access this information in Grafana through another Grafana plugin? I see that there is a CDF PostgreSQL gateway, but its documentation says that it’s only for writing data to CDF, so assume this cannot be used for fetching timeseries metadata through the Grafana PostgreSQL data source?  

Hi Experts, Few queries: Can I create a ML model directly using CDF functions? - I believe we can. If yes, how can I retrain a model without using any external AI platform? Can I use workflow orchestration to retrain a model with new data? Thanks,Aditya

I want to move data from CDF Raw Database in Dev and Load it to CDF Prod.Could someone please let me know if there is a way in Cognite. 

Hi Team, I want to change the message for the custom extractor’s run history message by python sdk. Right now, message says “successful shutdown” after successfully running the extractor, but I want to change it with how many datapoints are uploading and in how much time.I tried to do it by following methods:By using abstract class Extractor in our code to overwrite the _report_success method’s message.       2.By using this method  cognite.extractorutils.util.add_extraction_pipeline(extraction_pipeline_ext_id: str, cognite_client: CogniteClient, heartbeat_waiting_time: int = 600, added_message: str = '')       3. By using below class too:cclient.data_classes.extractionpipelines.ExtractionPipeline(id: int | None = None, external_id: str | None = None, last_message: str | None = None)  There is no way of passing the custom message here in my knowledge if it’s there let me know!And is there any way to pass logs in extraction pipeline?

How can we use hybrid configs (local and remote) in custom extractor utils?Edit: while trying to consume combination of local and remote configs (published in extraction pipeline mentioned in local config), it just loads local configs. example configs:type: localcognite:    extraction_pipeline:        external_id: extraction-pipeline-idcustom:    property1: some-valuetype: remotecustom:    property2: some-value 

Does Cognite copies all data from data sources to staging area?If yes, is there any limitation of datapoints/ size of data? Does size of data, affects the performance of CDF or any other functionalities? 

I have Cognite functions that are being reused, but I need to define correct inputs.Today I have scheduled jobs that run for each function/input and they depend on one another to run. I arbitrarily set 30min difference from the schedule for hopefully one start when the other finished. But I’m already seeing problems with timeouts, so I may need to break the functions in smaller steps so they can finish on time, but I won’t be able to hope the schedule match as this will be much more complicated than my current scenario.Today, while looking at the workflow I notice that I cannot pass a input for each function thru the UI. Is that intentional? Is there another way to reuse functions using workflow?

 Appears to be an obvious question, may have been asked before. Just wondering if there is an extractor available to read the spreadsheet files and load it into raw/staged data. The Excel can contain multiple spread sheet and perhaps with configuration each of that spreadsheet and its columns can be mapped to the staged tables/columns? 

I updated and published a new version of the flow. When I am trying to run the updated flow it is still running the older version.Below is the updated version -  Below is the version after initiating the Run  

How can the Cognite SAP extractor be linked to the SAP BW system?Could you offer comprehensive documentation regarding this connection?We are aware that the extractor mentions compatibility with SAP BW.
