Business Central 2021 release wave 1 implements a new strategy for ETag calculations with OData. You can now choose to exclude non-editable FlowFields and fields not included in a repeater control.
To support this change, the Web Services page has two new options, Exclude Non-Editable FlowFields and Exclude Fields Outside of the Repeater, which you can set on UI pages exposed as OData Web Services.
