CData BigQuery connector not executing when run as part of execution package

We are having issues running source objects when source is CData BigQuery connector.Execution of objects run fine when executed individually with Deploy and Execute. When the objects are added to an execution package, the execution package runs fine when executed manually. But when the package is run on a schedule, the package just “hangs” and never finish the job. This prevents next running packages from executing, until we kill the process.When we look at the running processes on the machine, it seems like the Timextender package is running as a process. But if we look at the ongoing execution processes in SQL Server, nothing is running.The Event Viewer reports issues with “The application-specific permission settings do not grant Local Activation permission for the COM Server application” at the same time the process started.How can we fix this issue and ensure BigQuery objects can run as part of an execution package?

Should multiple SQL statements be possible in the query tool?

In v20 and before you can define multiple statements in a query tool window. This can be handy when doing comparisons or dealing with wide tables. v20 statement 1 v20 statement 2 In v21 the second statement is simply ignored for SQL DWH instances and results in an error in Snowflake:v21 SQLv21 Snowflake ; separating statements Was this taken out of v21 or should this actually work like in v20?

Problem with project variable used in semantic model

Dear Support,TimeXtender version: 20.10.43.64In TimeXtender we have two project variables that we use in a data selection rule in a semantic model.In attachment "project variables settings” you'll see the settings of the two variables.The dynamic variable script that it has to execute is:SELECT CAST(MAX(LoadingDate) AS DATE) FROM FinFact.FacturatieControle to get the highest date. The other script will get the lowest date.In attachment "semantic model with data selection rule” you'll see the data selection rule in the semantic model. We want to filter the date dimension so that it only shows the dates which are in the fact table (FacturatieControle is the fact table).The problem now is that the project variable won't update although we set the resolve type at 'Every time’.Only a deploy and execute of the model will update the date filter. Can you help me with this issue? Best regards,Christian Koeken

Row level security Tableau endpoint

Shortly we will be implementing Tableau endpoints with TimeXtender. With respect to RLS, I read the following in the ‘Semantic Model-Level and Row-Level Security’ tutorial:Is it on the roadmap for TX to implement RLS on Tableau endpoints as well?Maybe you can elaborate on the mechanism behind the .tds endpoints, do these need RLS like you can configure in Tableau (i.e. by configuring something on the semantic model in TX which is currently unavailable)? Or do they use a connection to the DWH (SQL db), thus using the permissions on tables related to the users of the dashboards?

CarloCDOStarter

Hi all,I recently created a bunch of SQL logins in TimeXtender to use in our Database Roles we set. After I did that I found out I made a mistake and I removed those SQL logins from the database. However, when I try to edit a database role and try to Add a login, I still see the SQL logins I removed.To make sure there is nog caching or something involved I waited a few days before checking if they were still there.Does someone have a solution to remove those logins from the list? I don't want to create new names for my SQL logins just to avoid having the same name as the previous one. Although, if that is the only option I am willing to accept that as well. Kind regards,Carlo

How to manage measures in different SSLs

Hi all,what’s best practice regarding organizing/reusing measures in SSLs?In my example the customers uses a power bi endpoint and has created a set of measures used by users in power bi. Lets say these are financial measures. A few question regarding best pratice have now popped up:We want to reuse these measures in a different SSL. For example we have SSL for the financial department and one for the board of managers. We don’t want to duplicate the measures, because it makes it hard to keep them up to date. Is there a way to “copy” measures from one SSL to another or to reference measures from a different SSL? We want to “categorize” the measures. So lets say we have financial measures as well as logistics measures. Once we get to a significant amuount of measures, it’s hard to keep track of them. Is there a way to prefix them, add categories of something similar? We had the idea of creating empty “measure” tables in the MDW with a separate “Measure”-Database-Schema. But this also c

OAuth with authorization prefix "Bearer "

Hi,I am trying to connect to a REST API that uses OAuth2 authentication.The API documentation is very clear on what to include in the authentication: I have entered all this information in the REST CData provider and I can successfully use the provider’s “Authorize OAuth” button.However, when I try to test the connection, error “401 - Unauthorizated” is returned.In the API documentation, they state that the token needs a prefix “Bearer “.I suspect my error is caused by the REST CData provider sending the authorization header without the Bearer prefix, like so:Authorization: {ACCESS_TOKEN}Which the API of course does not accept. Is there any way to include a prefix to the token in the authorization header?

DW_SourceCode as natural key

Hi all, We ran into an issue with history settings in combination with the DW_SourceCode. We need the DW_SourceCode in our primary key as there is overlap in the sources and this ensures uniqueness. In the history settings we cannot choose the DW_SourceCode to be the natural key: Without this, history does seem to work, but when we enable Create new record when a deleted record reappears in the source We obtain the error Error during Data Processing for Table: Maintenance.Verkoopinfo at: MaintenanceThe column name 'DW_SourceCode' is specified more than once in the SET clause or column list of an INSERT. A column cannot be assigned more than one value in the same clause. Modify the clause to make sure that a column is updated only once. If this statement updates or inserts columns into a view, column aliasing can conceal the duplication in your code.I've looked into the stored procedure that produces this error and this snippet produces the error: -- History: handle deleted records IN

Sharepoint data source 'Authorize OAuth' not working

When configuring the CData Microsoft Sharepoint (23.0.8669) provider for extracting a Sharepoint List, we encounter a problem with the button ‘Authorize OAuth’. We are configuring the data source in ODX Server 20.10.40 and TX version is also 20.10.40.The following settings are configured:According to the CData documentation AzureAD should be used as Auth Scheme to leverage OAuth to authenticate, we also use this exact same setting and the same app registration for another data source using the Excel Online provider for which all is ok.However, when using ‘Authorize OAuth’ with the Sharepoint provided, we get the following error:What could be causing this? Changing the file or location for OAuth does not matter at all, we have also tried other versions of the provider but they all give this error. Also, changing Initiate OAuth to ‘REFRESH’ does not have an effect.

Best Azure VM size for ODX

Our ODX is hosted on a separate VM in Azure. We followed the suggestion to use the size DS2_v2, but we encountered frequent “System Out of Memory exception was thrown” errors that caused the ODX to stop. We are planning to switch to E2_ads_v5, which has twice the memory, but I am curious if anyone else has faced this issue and has any advice.

Excel Online connector sometimes fail with "Error while listing workbooks for drive"

Hi,I am running a legacy version of TimeXtender (version 20.10.40.64), where we have an Excel Online connection set up using CData ADO.NET Provider for Microsoft Excel Online 2022 (22.0.8389.0) as data source.This data source is configured to authenticate via Azure ‘client flow’, see picture.

SCD does not update correctly

Hi!I beg your pardon for this somewhat lengthy post, but I try to be thorough to avoid confusion. :)I have a problem with updating an SCD.We are moving an old adress history table from another system into a SCD in TX. It has gone well so far since the old system made one insert per person per day regardless of whether there was an update or not, which has made us go from about 108M rows to about 275k rows with actual changes. So far so good. :)The problem now is that have a hard time to get this moved table to update correctly from a new source. The setup looks like this at the moment: The MDW table KIR_Persons is the correct and prepared historical data from the old system where I have fixed the From- and To-dates along with the “Is Current” flag. The “break date” for the data from the old system is 2023-10-16 which is when I made the final export.The new source for the address data is the DSA table KI0VAA0POPULATIONPERSON_QT which is the result of a query table.

TimeXtender Training unable to add data warehouse

Hello to the community 😀 Currently I started the TimeXtender Training. I am at the point where I have to create the instances. Adding the ODX or SSL instance was no problem. But adding the MDW instance didn’t work out for me. The problem is that i can’t select any storage in the “Server storage type” field. It just says “No items found”. (While adding the ODX instance it preselects “Azure Data Lake” and I can just switch to SQL database”, but while adding the MDW instance it doesn’t give me these options) Does this problem occur to anyone else? Do I maybe have to change any configuration before the “add data warehouse step”? Thank you in advance. Kind regards,Tobias

Mapping set not working on renamed columns

Hi,In my DSA layer I succesfully added a mapping set for which the include rule has identifed two tables. All of the columns in my DSA table have been renamed so none of them align with the original names in the ODX. As a result, the mapping set tells me all of the columns are missing: This specific table was first added to the DSA for a single ODX table, then the columns got renamed and at a later moment I wanted to replace the mapping to a mapping set. Should the mapping set be able to cope with this? In essence, it would be just like doing it manually and using the ‘smart synchronize’ option. But the mapping set does not seem to work like that.Best regards,Kaj
