composite model server schedule refresh

Hi there,

I need your help please,

I use power bi developer server to upload my reports,

I have a report that uses composite model

Table 1 Direct query

Table 2 import storage

When i upload the report to the server i usually go to manage to enter the connection string

And after that i go to schedule refresh to set the time for schedule refresh time,

I know that Direct query doesn't need schedule refresh, but what about the import storage mode table,

It supposed to have a schedule refresh, right?!

Could you please tell me what to do?!

Because when i went to schedule refresh on this case i found it deactivated for all report!
