Using a data iterator with DS from universe only instancing the method .getRows() I get this error

The environment is SAP BOBJ 4.2 SP 100 and Lumira Server 2.1 SP1 with Lumira designer 2.1 SP1 TRACE.txt

Hello, please consider replacing Data Iterator with official getDataSelections API. For details please see https://blogs.sap.com/2017/12/19/dynamic-apps-in-lumira-2.1-iterating-over-a-resultset/ . The issue might come from the fact that many Universe data sources are master-data-only (having no measures). The Data Iterator component would need to be corrected supporting such result sets - use selectionShape=3. In Design Studio 1.6 such result sets were never supported, but did work in some cases.

Reiner.

Hi, thank you for the info. I used the getDataSelections API and it works. I will have in mind that exception.
