Hi all,

 

According to the documentation, if i extract new and changed records of a table Table with delta extraction, I should be able to access to these data using the placeholder <$Table> in transformation tasks.

 

I'm trying to set up a delta pipeline, but my transformation ends with errors, because the placeholder <$Table> seems not to be recognized, even if I launch the tasks in delta mode.

 

I have already set up delta extractions and I am doing mock trials to understand the error, which I paste here:

 

  • If I reference the placeholder with <$Table>, I obtain "ERROR: Syntax error at or near "<" at character 101".
  • If i reference the placeholder with "<$Table>", I obtain "ERROR: Relation "<$Table>" does not exist".

 

The structure of my delta transformation is:

 

CREATE TABLE TMP_Table AS (

  SELECT

    Field_1,

    Field_2

  FROM <$Table>

);

 

What could cause this error? Am i missing some further configuration?

 

Thanks

If the syntax is correct but you get a "Relation … does not exist" error in your delta extraction, please open a support ticket with the following information.

- Your full team URL of the data job
- SQL scripts of your delta extraction/transformation
- Error message detail
- Timestamp of the error occurrence

I am also facing similar issue.


I have opened a ticket to Celonis with all the evidences, i will post here the outcomes as soon as the issue will be understood


The ticket has been evaded, I post here a resume of the solution.

 

Essentially, delta transformations are not enabled by default and a support ticket must be opened in order to get them enabled.

 

In principle, this has nothing to do with the enablement of delta loads, which would require different operations and another ticket (even if in my case both delta transformation and load were activated together).

 

Here's the link to the new documentation provided by Celonis technical team: Data Integration - Delta transformation failure because "Relation does not exist".

 


Okay... Thanks for your response, Simone. I will raise the ticket as well for the enablement.
