APEX schema problem

user4049807Jan 11 2022

Hi,

I'm new in APEX and I got a problem with my schema. I have an existing database with lots of data, lots of table. These tables owned by one schema. When I try to create an application using that schema and I select an existing table, I get the following error message:
"Ajax call returned server error ORA-20987: APEX - Invalid schema name - Contact your application administrator. for Execute Server-Side Code."

Is there any settings (grants, privilege, etc.) for a schema that makes it to not working? What should I do? Is there any solution to fix this schema or is it possible for another schema to use this schema's tables for creating APEX applications?

Thanks for the answeres!

Andrew
