TimeXtender Desktop Q&A

Hi, I created a field StorageReportIndicator in a table to rank the records in the table. This rank is a SQL window function RANK which combines table fields initially loaded from the data source (StorageUnit and ReferenceDateTime below) and lookup fields via table joins (DSA.Datum table, fields WeekKey and DayOfWeek).  Goal is to have a rank to determine the first record of each week for each storageUnit. The outcome afer execution is that all records have rank 1 which is incorrect. I verified this with the same SQL statement in Management Studio.Could it be that this window function does not have the right result since the lookup is done after the rank is calculated? Note, the table is not historical and incremental. Anyone with experience with this case and is there a proper solution?

As shown in Figure Syncronize Task is sucessfully completed, but Transfer Task gets an below error “System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 ”PM even though my date range starts from 2002 and ends at 2023.Even though after suggestion by @Christian Hauggaard i have made changes in setting of Date Conversition and selected MS SQL Min/Max option, but once i change the setting then i gets the below error for same process,“System.Data.SqlClient.SqlException (0x80131904): Execution Timeout Expired.  The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out”(This error is geeting for those tables who has Date Column, and date column has such data (for example 03/01/2022 6:42 PM ) )​​​​​​​What are steps to solve above error? 

Hi all, I have an data source that gets daily refreshed in the ODX. With some tables, I have encountered the following error. Does anyone knows how I can resolve this? Thanks in advance!

While Running Transfering Task im getting error “Transfer Data from Data Sourse with Incremental Load”after appling incremenatl Load, again im getting Same error.

Hello, For two weeks my clients Power Bi report was refreshed daily without issues. Last week this changed after the TimeXtender Execution server stopped running. I ran the TimeXtender ODX Server Configuration on the desktop and started the TimeXtender execution server again. The next days the execution jobs where triggered again but I would like to know why TimeXtender Execution stopped running in the first place.  How could this have happened?     

This it’s the Snippet with the descriptions in the parameters: When I use the snippet, the description it’s missing: 

After upgrade to the new version all the measure’s definition has disappears: I’ve send the issue to support.

Hi,Need help on the following : I have built the entire SSL model is built on Analysis server & want to understand what is the best practise around this? We have one base model built & users can access all the tables & can be confusing to the user which table & column to pick from. We have tables from Finance, Operations, production, Purchasing everything. How do you segregate & manage scenario like this? We did explore Row level security, but it is no good & we need to use Object level security which is not supported by TX.

In query table all tables are visible but while adding table in MDW(In select table option ) no tables are visible.

The column LVALUE from the table "PROD"."MICROSOFTDTPROPERTIES" failed synchronization with the error:System.Exception: Invalid data type long raw.how to solve this error. 

Hi,our customer has a dimension table with a parent-child architecture he wants to use for RLS. The table looks something like this:cost_center, name, parent_cost_center1, management, NULL2, teamlead_1, 13, teamlead_2, 14, worker_1, 2In Power BI I would use the PATH() function to create the hierarchy as an additional column for every row (e.g. “1 | 2” for teamlead_1)  and then use the PATHCONTAINS() function in the RLS settings to check, if the current user’s cost_center number is in the hierarchy column.I have not figured out how to implement this is TimeXtender. Does anybody have some experience on this topic?

I have a API endpoint with pagination:https://www.mytestserver,com/DWH/api/v1/all-buildings?buildingType=BAR&page=5I have created a RSD file with the following code after  </api:info>  <api:set attr="in.Header:Name#" value="Accept"/> <api:set attr="in.Header:Value#" value="application/json"/> <api:set attr="in.DataModel" value="FLATTENEDDOCUMENT"/> <api:set attr="in.JSONPath" value="$.data"/> <api:set attr="in.EnablePaging" value="TRUE"/> <api:set attr="in.Page" value="1"/> <api:set attr="in.PageCount" value="100"/> <api:set attr="in.BaseURI" value="https://www.mytestserver.com/DWH/api/v1/all-buildings?buildingType=BAR&page={page}" /> <api:set attr="in.ElementMapPath#" value="/json/meta/pagination/pages"/> <api:set attr="in.ElementMapName#" value="pages"/> <!-- The GET method corresponds to SELECT. Here you can override the default

I’ve read the artical Enum and page method but we still have a question how the json response and the RSD file should be.It would be great if anyone provide a full example (json response data and the RSD) so that we can fully test.Thanks for advance!

If you see Task are sucessfuly completed in ODX, and tables are vissile in query tool, but while loading data from ODX to MDW in select Table options tables are not visible, as shown in Figure

Hello,we're using Timextender with ADF for the data movement between our Data Lake storage and SQL Database. Running the execute from TimeXtender of rerun it within ADF the performance is poor (slow!).Our setup at the moment, regarding to the specs within the topic "Create a Demo Template Project TX SaaS”. We wanted to start basic and then tweak the settings for better performance. Executing the first SQL DatabaseService tier: General Purpose Compute tier: Serverless Hardware:    Standard (Gen5), Min/Max vCores 10 and 30GB Min/Max Memory Auto-pause delay: 1 hourIntegration Runtime - type AzureComputer Size: smallWe tried using a different Computer Size on the IR and also changed the SQL DB Tier for more DTU. No performance improvement after changing.Looking at one of the jobs we are transferring 2048 rows from our Data Lake to our Azure SQL.The Queue is taking most of the time. We did some research on the support page of TimeXtender (No topics) and also at the Microsoft community. Ther

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?

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?

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 

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?

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

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

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?

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

Hi, can you provide me with detailed instructions on how to set it up?
