@o.becke i thinks one of the history settings might be wrong. If i'm understanding it correctly you are not getting new records for items that are inserted into your source table:
You probably would want your settings to look like this:
 

If you want to have records reaaper if they are deleted you will need to check the create a new record when a deleted record reappears in the source. And make sure that treat type 2 fields as type 1 when the previous field value is null is check off

Also if your source is already a historical table. then i would suggest not using the history table in TimeXtender but stay true to the source table.

Thanks Bernard. Let me work on that and see how it turns out. I did not have this setting checked. Besides that i have new records valid from 1900-01-01, is this also an issue?

No that's not an issue, you can choose whatever one you would like i was pointing more at the first options.

@o.becke Did it fix your issue?

Hi Bernard,

Thanks for checking. We have implemented it and saw some changes but some were unexpected. So not sure if everything works as expected. I, however, believe it helps. So we can close this topic. If i identify something related to the settings then I will reach out again.

Thank you very much for your support.
