Hi,
If you are using BEX analyzer, you should install a patch inorder to be able to see the error messages.When you install the patch successfully you will see the option "Display Messages" enabled in the drop down options.
The patch to be installed is BI740SP04P_401.EXE or any higher version.
And coming to the PE error you have specified. It is specific to the HANA database , you can raise an incident for the same.
and for the below question
Also, you mentioned "check if the query is input enabled in the query properties". But I can't find a setting where we can set "input enabled" for query. I can only find setting of each KF. Are you referring to KF setting in query?
1.Open query designer.
2.In the properties tab on the right.Select the query.
3. Under planning tab , Check the box "Start Query in Change Mode".
Hope this helps
Regards
