Hi Rajesh,SAP released a note on this issue, 2315747 (https://launchpad.support.sap.com/#/notes/2315747/E).The note refers to SQL-based installations, but you should check it, maybe it applies to HANA as well.

Thank you, David.Your reply was very useful, especially as SAP Note is not accessible anymore.I had the same error and it was caused by the fact that the name of the UDO that I was trying to update via DTW contained spaces.
