Hi Andres,

This issue should be caused by the single-line comment symbol '//', PowerServer only support multi-lines comment symbol '/*…*/' in datawindow, and PowerServer does not support char ':' in comment, please solve this issue by using multi-lines comment symbol '/*…*/'.

Hi Andres;

   Please open a Support Ticket on this issue.

   FWIW: A workaround could be to parse out the DML comments in the DC/DS's RetrieveStart, SQLPreview or right after the DWObject's load (ie: Post Constructor) event before PowerServer processes the current SQL and replace it with a cleaned-up copy of the DML statement. Hopefully, you have a common DC/DS ancestor where you can implement this code. Replacing the DML would only be "in memory" so the DWO source would not be affected.

   Note that you would only have to run the SQL clean-up code logic when running under PS as a Web or Mobile App. So you could check the Client Type in the "appeonextfuncs" object located in the Appeon_Workarounds library for that (method: of_getclienttype).

HTH
