Hi Mohammed,
Can you check if you can access that Analytic View using Excel? If you are unable to access the analytic view using excel, then it probably has to do with the view missing from certain tables. Please execute the below statement if you are unable to access from excel -
update "_SYS_REPO"."SCHEMAVERSION" set db_schema_version = 16 where schema_type = 'bi'
After executing the above SQL statement, it is advised to reactivate all the views again. So reactivate your analytic view and then see if it is accessible from excel. If it is accessible after performing the above, then retry your MDX query.
However if it is already accessible via excel then I am not sure what else could be your issue. Also I have not done any configuration such as setting schema, in fact setting the schema just throws an SQL error for me.
You may want to open an OSS message or post to the HANA Dev Center as you might get further help from there.
Thanks,
Sharan
