Can one MBT service (Mobile Backend Tools) map entities to many different HTTP destinations ?

[Momen_Allouh]

I am planning to use MBT service for caching data in SAP HANA and to use with offline MDK app , the results of each entity may be from ECC ODATA or HANA DB or another HTTP ODATA.

In Mobile Backend Tools, Can I map the service entities to many different HTTP destinations ? or one MBT service use only one backend destination (source of the results).

like in this e.g. can I use the HTTP.Destination to define from where each entity should be loaded into my MBT service.

<EntityType Name="CashDecreaseType">
    <Annotation Term="HTTP.Destination" String="ECC_ODATA_1"/>
    <Key>
        <PropertyRef Name="StoreNumber"/>
        <PropertyRef Name="PurityCode"/>
    </Key>
    <Property Name="StoreNumber" Type="Edm.String" Nullable="false" MaxLength="3"/>
    <Property Name="PurityCode" Type="Edm.String" Nullable="false" MaxLength="3"/>
    <Property Name="CashDecrease" Type="Edm.Decimal"  Precision="13" Scale="3"/>
    <Property Name="DecreaseUom" Type="Edm.String" MaxLength="3"/>
    <Property Name="LastChangedBy" Type="Edm.String" MaxLength="12"/>
    <Property Name="LastChangedAt" Type="Edm.DateTimeOffset" Precision="7"/>
</EntityType>


<EntityType Name="CustomerType" >
    <Annotation Term="HTTP.Destination" String="ECC_ODATA_2"/>
    <Key>
        <PropertyRef Name="CustomerID"/>
    </Key>
    <Property Name="CustomerID" Type="Edm.String" Nullable="false" MaxLength="6" sap:display-format="NonNegative" sap:text="LastName" sap:label="Customer ID" sap:quickinfo="Flight Reference Scenario: Customer ID"/>
    <Property Name="FirstName" Type="Edm.String" MaxLength="40" sap:label="First Name" sap:quickinfo="Flight Reference Scenario: First Name"/>
    <Property Name="LastName" Type="Edm.String" MaxLength="40" sap:label="Last Name" sap:quickinfo="Flight Reference Scenario: Last Name"/>
    <Property Name="Title" Type="Edm.String" MaxLength="10" sap:label="Title" sap:quickinfo="Flight Reference Scenario: Title"/>
    <Property Name="Street" Type="Edm.String" MaxLength="60" sap:label="Street" sap:quickinfo="Flight Reference Scenario: Street"/>
    <Property Name="PostalCode" Type="Edm.String" MaxLength="10" sap:display-format="UpperCase" sap:label="Postal Code" sap:quickinfo="Flight Reference Scenario: Postal Code"/>
    <Property Name="City" Type="Edm.String" MaxLength="40" sap:label="City" sap:quickinfo="Flight Reference Scenario: City"/>
    <Property Name="CountryCode" Type="Edm.String" MaxLength="3" sap:display-format="UpperCase" sap:label="Country/Region Key" sap:value-list="standard"/>
    <Property Name="PhoneNumber" Type="Edm.String" MaxLength="30" sap:display-format="UpperCase" sap:label="Phone No." sap:quickinfo="Flight Reference Scenario: Phone Number"/>
    <Property Name="EMailAddress" Type="Edm.String" MaxLength="256" sap:label="E-Mail Address" sap:quickinfo="Flight Reference Scenario: Email Address"/>
</EntityType><br>

Yes you can. If you check vocabularies/com.sap.cloud.server.odata.cache.v1.xml, and look for the HttpDestination term, you can see the "AppliesTo" permits this.

it AppliesTo EntityType also EntitySet, where do you think is better to add the annotation in EntityType or both ?
