WEBI on ERP/ECC Unx: "Unknown property : PROJECT_SELECT_FIELD"

Hello experts,

we try to build a WEBI Report on top of a SAP ERP System.

Using IDT we build the connection to our ERP System via the SAP JCO Connector (New Relational Connection -> SAP -> SAP ERP6). The data fetch works perfectly in the IDT/Universe (Information Design Tool 4.2 Sp3)

Now we want to utilise this Universe with WEBI 4.2 SP3 but this seems to be impossible, we are able to select the Universe as data source for WEBI, but retrieving the data produces the Error:

„Unknown property: PROJECT_SELECT_FIELD"

This issue relates to both the WEBI Rich Client as well as the JAVA applet

Searching for this error gives no results, neither in the sap community, nor in the www

We are able to utilise the same Universe as data source in Crystal Report Enterprise. The data can be retrieved here without any issues.

Any suggestions what what to do?

Kind Regards

Hi Agata,

Can you check whether are you creating Data Foundation as Single source or Multi source ?

Please refer the below link as well:

Hi Chanukya,

after some difficulties we are finally able to build a Webi Report on the ERP Data via a Multi Source Unx (as described in the linked thread)

Thank you very much for the link.
