How can I conditionally fill down/flash fill NULL values with previous values based on certain criteria?

I would like to be able to flash fill down NULL values in my DSA table with certain conditions.In the table below I have multiple NULL values. Take for example the column ‘CardCode DUAL’.Row 2 with Company key MTW and project 1201121979 shows for CardCode DUAL DB0006. I would like to show value DB0006 also for all other rows where company key = MTW and project = 1201121969.Same for Route Bron column. I would like to fill down NULL values on the most recent NON Blank value for that Company_Key+Project combination.I think it should be possible with a self join or self select, but not sure how.

Duplicates loading data from ODX to MDW

Hi community,we are facing the problem, that we create duplicates when we bring data from an ODX API source to the MDW. We are working with an overlapping sliding window of two days in the schema file (because data can change and there is no last modified date) and only set the primary key on the ODX source.In the MDW (dedicated SQL pool) we enabled the history and set the ID as natural key. All fields are marked as type 1 fields.The execution brings us duplicated ID values - no updates are madeThanks for your helpMichael

We are using Business unit to land our data in the DW. We have a few columns where we need to obfuscate some of the data.At what point should a script action be placed to update the field in the raw table prior to the data being moved into the valid table, so our script does not need to include an update to the field in both the raw and valid table. the script uses UPDATE table SET column

SCD Surrogate Hash Key is non-deterministic.

Hi,I obtain a deployment error when I try to make my table historic. Computed column 'SCD Surrogate Hash Key' in table ' <mytable>' cannot be persisted because the column is non-deterministic. I think this has to do with the excessive amount of columns in the table: 695 columns, all varchar(2000). What confuses me is that when I set the hashing algorithms to debug, I still get the same error I don't have any transformations on this table, its a straight copy from to ODX. Is there a limit on the amount of fields a History table can have?

TX crashes when adding 'Additional Connection'

Hello,We have a data source that contains several additional/stacked connections in our Business Unit. We now wanted to add the 4th additional connection (so in total 5 data connections), but TimeXtender crashes when clicking on OK after configuring the connection. I think it tries to connect to the data source and get meta data for the tables it needs to select but somehow this fails. Found this in the Event Viewer: The errors are as follows:.NET = System.OutOfMemoryExceptoiin Application Error = Faulting application path: C:\Program Files\TimeXtender\TimeXtender 20.10.38.64\timeXtender.exe Faulting module path: C:\Windows\System32\KERNELBASE.dll Application Error = same as 2.)We are on version 20.10.38, do you have any idea what might be causing this? Why don't we get a proper error message in TX interface?Connection to the data source through SSMS is working without any issues by the way.Best regards,Kaj

Most optimal way to check if Value of Table A, Column A is also in Table B, Column A

I’ve got the following user request but I am not sure what the most optimal solution is, as i can think of many possibilities.I’ve got 2 Facts Tables:DSA.Fact_Turnover DSA.Fact_TransportOrdersBoth Facts contain the ‘Project’ column. The user request is to finally get the Turnover for all projects which are in Fact_TransportOrder. What is the most optimal way to get a check column to see if the Project value of Fact_TransportOrder is also present in Fact_Turnover and why? I want to use this filter column to eventually only present him the Turnover for projects which are also present in the Fact_TransportOrder.I’m really curious, as I already have such solutions, but am not sure if there are more easy TimeXtender functions or tricks which i’m not using currently.

Object security, allow execute of stored procedures on specific database schema

Hi community,I created a role in the MDW and added Grant permission on one specific database schema. This schema contains some tables and some Stored Procedures. This role need to be able to select data in the tables and execute the stored procedures. I created my Object Security Setup using these settings: When I login using SSMS (using the user in the role), I see the correct tables and I'm able to select data in the tables. But I'm not able to see the stored procedures. When I check the permissions on the ‘ExcelAddin’ database schema. Only the ‘select’ permission in granted. Is it possible to grant permission for ‘execute’ as well? Using TimeXtender?

Table Relations using Greater than or Less than Operator

I am setting up a table relation where the tables join based on a date range (see screenshot below)In setting this up in TimeXtender, I noticed that I can only set this up on the lookup field and not as the default relation between the tables.Does anyone know of a way this can be setup on the default table relation? Or can we had as an enhancement for TX?(NOTE: I have edited the table names and columns for this post)

SQL Case When Statement not working correctly with TimeXtender

In my DSA I have my Business Partner Master Data. I want to add a field that named Intercompany that shows ‘Intercompany’ when BP Group Code = 104 or 109 and else show Extern. BP Group Code has a smallint datatype. I added a custom field with the CASE WHEN statement. However, the extra field does not show the right results.When executing the CASE statements SMSS everything works fine, but when I implement it in my DSA, it does not work correctly.I tried all kinds of CASE statements with e.g. Like,OR statements, strings, however it does not show the desired result, but rather tons of nulls.The screenshot below shows the intercompany field with the Nulls and some tests CASE statements.

Is TimeXtender compatible with SQL Server 2022?

While running trials of TimeXtender it is fairly common to run against SQL Server Developer Edition. As SQL Server 2022 has been GA since last November, this is the version people will generally be installing.Finding 2019 is fairly hard. I have noticed that the 20.10.37 ODX Server is perfectly happy, but that TimeXtender 20.10.39 gave me an “Unsupported version of SQL” error, even with databases running in SQL 2019 compatibility level. Is this supposed to be the case?Azure SQL DB is 2022 under the hood, even if SELECT @@VERSION states something else.

Connect to Excel files

I'm following the steps explained on this page https://support.timextender.com/data-sources-112/connect-to-excel-files-with-excel-online-628#Connect+with+the+Excel+Online+CData+provider, but I couldnt get it. I used Microsoft SharePoint Excel Provider.I have a 48 Excel file. I uploaded them to my company's onedrive. I then gave OAuth to Cdata. But I took this error. ‘You must specify an Excel file: Set the FILE property to an .xlsx file.’ The file url address where the excel files are located like this:https://companyname-my.sharepoint.com/:f:/g/personal/xxx_companyname_onmicrosoft_com/xxxxxxxxxxxxxxxxxxxx Now I have written this above address in the 'URL' section under 'Authentication'. Is this true? Or should I specify in the 'Folder' and 'File' sections in the 'Connection' section? Which Auth Scheme should I choose?

Table Inserts and Object Dependencies

I have a table with a table Insert from a view (actually multiple views) underneath it. The problem is that this table sometimes is empty because the Data Lineage is wrong. It seems that we need to have Object Dependencies for Table Inserts. 2 Questions about that: When creating a "Table Insert" get a message that "Object Dependencies" are required? Is it enough to check the next child view (in my case) in the "Object Dependencies" if you have one table insert? Or should it be the first child table? Or should all underlying views/tables be included?

Audit trail modified GDPR-related objects

Hello,In order to be able to answer all related questions regarding GDPR, we are designing a TX solution that allows us to track all tables/columns that contains sensitive information. Most importantly, we make use of tags so we can track the columns throughout the DWH.An additional question we got is if it is possible to keep track of changes in the TimeXtender projects. In other words, who added which column (with sensitive data) to the project and when? What is the best way to keep track of these things and is there a solution in TimeXtender available that we can use to provide this information? Probably we should use the data in the TX Repository, we were curious if you have had this question before.

Incremental load with Table Inserts and Views

Hello,Current Setup: TimeXtender 20.10.31.64 and ODX 20.10.31.I need help setting up incremental load on a rather different type of data flow from the standard one, that has table inserts and views inbetween tables.The flow is as follows:Table A (has incremental load today) => View1 => TableB => Table C(MDW) once directly but also through View2.Both views are necessary so we cannot remove them. My question is how to setup incremental load in timextender on this solution, if it is even possible. I am not sure how to do it through a view. Currently there is only an incremental load set up on Table A and then we fully load table B and C. Thank you
