$count automatically appended to OData request

Dear experts,

I am using a SAPUI5 table (sap.ui.table.Table) in combination wtih OData. When I have look in the network trace of firefox or chrome I see a second OData request next to my. This one is the same like I have bound to the table, but this secound one has an automatically appended /$count.

This is not the problem, the problem is the response form the server which has a size of 10 MB.

I already set the following parameters to the table:

Any ideas how I can deactivate the $count? My be its possible to deny this in the OData service?

I think it  could  be some default settings of the table control...

Thanks,

Matthias
