---------------------------------

             Summary: Mention use of ETag with bound function: only process if binding entity matches ETag
                 Key: ODATA-1582
                 URL: https://issues.oasis-open.org/browse/ODATA-1582
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: Protocol
    Affects Versions: V4.01_OS
         Environment: Proposed
            Reporter: Ralf Handl
             Fix For: V4.01_ERRATA01


Section [11.5.5.1 Invoking an Action|https://docs.oasis-open.org/odata/odata/v4.01/odata-v4.01-part1-protocol.html#sec_InvokinganAction] explicitly mentions how {{If-Match}} can be used with bound action calls:

{quote}To request processing of the action only if the binding parameter value, an entity or collection of entities, is unmodified, the client includes the If-Match header with the latest known ETag value for the entity or collection of entities. The ETag value for a collection as a whole is transported in the ETag header of a collection response.{quote}

The same use case applies to bound functions.
