SAP reader (Theobald software) node - Hierarchy extraction issue

The SAP reader node works fine except for the Hierarchy extraction.

In the XtractUniversal software the data from Hierarchies can be extracted and send it to a csv file, however, while using the node in KNIME, no data is displayed while using a hierarchy extraction, for other extraction types (BW Query, table, etc.) it works fine.

The node looks like reading the data but the data cannot be displayed, I tried all different encoding types as I thought this could be the issue, however no data is displayed.

The error message I get from KNIME in the console is as per below:

ERROR SAP Reader (Theobald Software) 0:618 Error while mapping row ‘1’

ERROR SAP Reader (Theobald Software) 0:618 Error while mapping row ‘458’
WARN SAP Reader (Theobald Software) 0:618 Node created an empty data table.

I checked with Theobald but they just referred me to you.

Any help on that will be appreciated.
Thank you in advance.

As just discussed and found out via the knime.log (thanks @tobias.koetter), the Theobald Node does not tolerate missing values in Date-Type columns - this will be fixed in the next Bugfix release 4.4.2 (internal ticket reference: AP-17456)

… and welcome to the Forum, @MarcEM!
Thanks for reporting, best,


As @LukasS said this fix is included in version 4.2.2. which is available from last week.


Thank you!

I can confirm that it works now the Hierarchy extraction, however, I have still this issue with the BW Query extraction if there is a Date with value ‘#’, could you please help?
