Offline OData Version SupportLocate this document in the navigation structure

OData version 2 is supported for the offline OData feature, with several exceptions.

  • There is no support for these OData concepts:
    • Function imports.
    • ETags when using the if-match/if-none-match headers when performing LOCAL reads.
    • Modifying properties or complex type properties by addressing them in the URL.
    • Metadata annotations are not populated in the Metadata object.
    • Modifying entity relationships through entity bindings in entities.
  • The Offline OData feature has the following limitations:
    • The maximum length (MaxLength) of Edm.String key properties is 512 characters.
    • The maximum length (MaxLength) of Edm.Binary key properties is 1536 bytes.
    • The Android offline store does not support mutual authentication using X509Certificates loaded from the System KeyStore/KeyChain. It does support X509Certificates which are provided from a secure file store. The secure file store may be an SAP component, or 3rd party component, so long as the X509Certificate is supplied to the X509KeyManager when required.
    • The navigation property used for the deep insert must refer to at most one entity.
