Krishna,
Thanks so much for your reply. Exteremely helpful.
We have been struggling through some of the standard delivered services and UI5 applications (swim lanes).
I have created a REST service to handle updating the frequently used counter, so much smoother and easier. I think this is the route we will go.
However, not to hijack my own thread, but since we started down the oData route initially, I have not been able to get my gateway service to work. I started by creating an entity called linkid that is simply a string and an entity set that is made of those links. However, I have not been able to get the update entity method for the entity set to work.
I am trying to wrap my mind around what we are trying to do and that we aren't really working with an entity set in the traditional sense, but rather importing a key (reference id) and expecting something to happen in the backend but not really updating that entity.
We originally put this in the LINKS_UPDATE_ENTITY method. But we aren't even getting that far. I have googled the message returned but am still somewhat lost. I am back to wondering if this really shouldn't be in an update method at all, but rather in the execute_action method and whether we should just be doing this with a function import rather than trying to do a put.
We have created other GW services, but they all have traditional entity sets and there is a get implementation in addition to the update and deletes and that all seems to make sense. This one just seems odd as what we are trying to do is very focused and seems to be missing half the parts and I'm wondering if that's the problem....
