Setting the backend OData Service Alias in a BTP Destination. Possible?

[BrendanFarthing]

Hi,

We have a scenario as follows with BTP UI5 apps making OData calls to backend ECC systems:

BTP Cloud Foundry UI5 App > BTP Destination > SAP Cloud Connector > Gateway Hub > ECC (NW 7.00)

For a very specific reason we would like to set the Alias assigned to the OData service on the Gateway Hub via the BTP Destination, rather than inside the UI5 app itself, or via other external means. I'm talking about the ";o=<ALIAS>" part of the OData URL.

I am hoping that SAP have some internal option within the SAP BTP Destination service (specifically on Cloud Foundry) which can inject the ";o=<ALIAS>" into the correct place in the OData URL if we specify it in a special Destination Property.

I have searched high and low and tried various properties like "sap-system-alias" or "sap-system" but they don't work, or were designed to work somewhere else. I have also tried these names and some others as HTTP Headers as a guess, but no luck.

Anyone have any idea if an 'Alias' Property exists in Cloud Foundry Destinations which can do what I need?

Note also that we are very experienced with all of this and know every other possible way to handle Aliases on OData calls in relation to BTP, ECC or S/4. But we have one very specific requirement where using a BTP Destination would save us a lot of hassle.

Thanks in advance,

Brendan
