Hi all,  I need to create an Identity column, How could I create it in TX? Thanks Ignacio

Hi, Let's assume I am importing from CSV file. The Data is very dirty and somehow I have stings in my int filed "ID" so the filed is interpreted as NVARCHAR(MAX). If I change data type of the field (right click > Edit Field) from string back to integer I receive a runtime error during the execution. What I was expecting was to see was corresponding entries in the _M and _L tables. Is this not part of data cleansing after all? We have this problem all over and could not find a better solution than to build custom views with TRY_CAST etc. where we lose lineage etc. What is the best way to clean up such data (keep valid rows, write errors/warnings on invalid rows)? We are talking 100+ tables so I'm looking for a highly scalable solution here not a one time work around. Thanks and BR, Tobias

After trying to import data from a REST source in the ODX I got an SQL Exception with error code 4815.After a bit of Google I ended up on this page, telling me that it had something to do with SQLBulk copy not able to match the columns in source and destination or the value of a column was larger than in the destination allowed (e.g. string with length of 200 -> nvarchar(100)).Because TimeXtender defines the columns it probably didn't have something to do with that.Because the RSD I created didn't have a column size specified, all my string type field allowed 2000 chars. Thinking that none of the string fields were going to be larger, I started changing int to double and after that all the fields to string and later even to text. None of this worked which send me back to start. After properly examining the parquet

Hi, I'd love to get your thoughts on issue we're dealing in the past few days. We've noticed that transfer time from ODX to DSA is growing rapidly. This as significant impact on total running time of DWH and SLA towards our clientExecution log of DSA As you can see. as insert and cleansing tasks remains pretty much the same, transfer time is growing.In terms of volume, data hasn't grown significantly   Batch Id 13428 (first) - 46347863 rowsBatch Id 13481 (last)  46536187 rows (+0.4%)difference in transfer time is more apparent as you zoom in into the package execution (Gantt chart)Batch Id 13428 

Data Source selection in Project Perspective (already has been asked for in 2019) - to filter the list of hundreds of sources to those related to the specific project. Data Source "guarding" to prevent accidental modification in DEV or TEST environments, when a source is already actively used in PROD environment. Data Source disable option (in conjuction also with guarding) - various use cases.

Hi! Does TimeXtender support retrieving data from a MySQL RDS instance in AWS? I have tried to connect but I did not manage to test the connection successfully. Thanks a lot in advance, Bernardo Di Chiara

I am new to TX and data lakes.  I have a common problem that others have commented on and would like to know if: 1) The functionality now exists, or if it does not 2) How are others getting around the issue? The issue is that I need to be able to segregate data sources in the data lake.  I am pulling in data from multiple SQL sources where the source schema and table names are the same, and I need to differentiate those tables in the data lake.  By schema would be best, but if that is not possible, I need some other ideas.  Thanks!

Hi, I am a bit unclear on how to configure Max Threads for an execution package. The way I perceive it now is: if I run on 4 cores, I choose 4 Max Threads, if I run on 16 cores, I choose 16 Max Threads. i.e. N Cores -> N Max Threads. Is this the correct approach or are there other factors that need to be accounted for? 

Hello, I have a problem that i am struggling with. I have a table that contains field called [Period] and it stores month dates in following int format: 2201, 2202, 2203 which i need to translate to 2022-01-01, 2022-02-01, 2022-03-01 etc. to date format (always 1st day of month) The problem is i can convert the source format to date format in the view, but when i am trying to generate a table from that view, i always get an error that [Period] cannot be converted to date format. I have different options and nothing has worked as timextender always fails to convert to date format. Everything that failed on timextender, worked perfectly on MSSQL so i am not sure what is wrong. Thanks for your help

Dear CommunityIf I'm clicking on Report->Errors or Warnings then I see a fulll list of them. Where are those records stored? In which table can I find them ?My problem is that once forgot to check the "Error" manually, therefore I want to create a script which regularly should check if errors exists.But wo far, I couldn't the table/view/place where this Infos are stored.Any ideas? RegardsAlex 

Hi,I'm searching for a way to get a table insert incremental. I have a table (about 30 million records). This has a row for each hour of the day for 10.000 machines, so this table is getting bigger very quickly.I do a lot of transformations in this table. This resulted in a load time of over 10 hours. I've discussed this with our TimeXtender Solution Specialist and we've decided to split the table into multiple smaller tables. Now I do have 1 table (loaded incrementally from ODX), this table has a lot of lookups and simple transformations. This table is loading quickly because it's incrementally loaded.The result of this table is inserted in a new table (Raw table), using a table insert. This table is converting cumulative numbers to noncumulative, using the SQL functions LAG, OVER, PARTITION BY and ORDER BY. Because it is a table insert I have no idea how to do this incremental. I've set NonClusted Indexes (also on Raw table) on all fields used in the PA

When we perform a transfer from the acceptance environment to the production environment, there are settings that you do not want to take with you. First the time schedule. We have an Execution package for both acceptance and production. These should run at different times.  Secondly, the acceptance environment naturally refers to other TimeXtender databases than the production environment. Nevertheless, the database links are taken literally after the transfer.  Third, when you accept a change in acceptance, you transfer to production. However, when you have executed these, the sources are literally copied from the acceptance. We have circumvented the latter by allowing acceptance to refer to production, but this is not always desirable. Fourth, it would be nice to be able to include project perspectives during the transfer. It would be nice if you could set the above points as settings to transfer. 

I have recently been experimenting with using .rsd files for REST API data sources.  I have generated the .rsd files and then modified them to add pagination.  I now have two questions: 1. What is the appropriate way to move these .rsd files to production? Just copy the files, to the production server? Or is there some way in integrate the movement with the TimeXtender transfer to production process? 2. When moving the .rsd files to production, how can we have them dynamically use the URI for the production data source instead of the dev data source?  If we just copy the files from dev to prod, the files will still contain the dev data source.  Do we have to manually change this, or is there a way to pass this source address using a variable? Thank you.

Is it possible to or are there any limitation on using composite models in PowerBI in unison with the Semantic model created on TX? Regards Mads 

Hi Is it possible to use DAX Studio og Tabular Editor on Semantic models?Regards Mads

Never had this before ...Trying to execute just the object I am working on..It auto selects the whole project ...where to change that setting...Very strange...20.10.25.64 

After the upgrade this error is raised for various (not all) tables when trying to execute from SQL Server source.  It includes some table names with the "_FDS" extension. I tried googling the _FDS but nothing comes up, neither in TxT documentation nor outside.  Anyone who can give me a clue on how to proceed?  Error example:"Cannot find the object "DIRPARTYTABLE_FDS" because it does not exist or you do not have permissions." I can solve this be re-deploying each table but of course that is a very sub-optimal choice :(

When I do 1 on the exercise, I get a pop-up information message "No constraint suggestions are available" Right click DSA node and choose Automate -> Add Suggested Constraints Don't know how to resolve this?

We want to extract data from the CBS (NL) this is a dataset with minimal 100.000 records and the connections allows a maximum of 10.000 records. https://dataderden.cbs.nl/ODataFeed/odata/03759ned/TypedDataset.xmlIs there a possibility to make a connection that downloads each time a set of 10.000 till all records are downloaded. 

Hi all,I'll try to find out how to get rows in the _L table when I use a field validation. For field validation I can decide if I get a warning or an error information. But I only get a message in the _M like this:How can I get the rows that don't match the field validation criterion to get an entry in the _L table? 

Hi, we are receiving a file where the order of the rows is important information that needs to be maintained for our transformation process. When TimeXtender loads a text file, are the rows loaded in order? (I.e. will the DW_Id in the Business Unit table act as row numbers of the source table). Thanks, Mark

Hi all, I have not been able to find any similar posts. My problem is that I stumble over an execution error when trying to map two different sources with identical columns, except one, that only exist in one source. I except data from one of the sources into the column and expect Null from the other on the lines originating from the other. But however Timextender throws error "Invalid column name 'XXXXX' " on the column at execution. Have tried full deploy. Only if I remove the XXXXX column it will execute. Any ideas?

When I have two tables, how can i make a left outer join between 2 tables. Or do i always need to use a custom view for this situation. Table 1 = Adressid = 1id = 2Table 2 = Relationpersonid = 1personid = 2Table 3 id = 1, personid = 1, personid = 2id 2 , null

Hi, I am following the tutorial to set up a sandbox environment. However, I get an error message at the end of the configuration I get an error: Can anyone help me resolve this issue?
