Odata PerEmail - Purge mode - SAP HCI

Hello -

Calling PerEmail Odata APi in SF - able to upsert the record in SF however before upsert I wanted to perform Purge operation either full or incremental.

I dont see any option in SAP HCI odata adapter to use thise parameter. My requirement is to delete the record first and then upsert the record through Odata API.

SF Odata ref API suggested to use Purge option but not sure how to use it.

let me know if I can use any other options using other comm channel.
