Hello folks,
following up from my prior thread https://answers.sap.com/questions/276665/analysis-options-required-customer-task-provider-f.html and with respect to Resmi's Blog https://archive.sap.com/documents/docs/DOC-53315:
I've created a basic and, by now, working configuration for the implementation of a Custom Task Provider on a Gateway System, ultimately for visualition within the standard App Fiori My Inbox 2.0. The backbone for that implementation is a facade class inheriting from /IWPGW/CL_TGW_TASK_FACADE_ABS, as per official Documentation. After doing a bit more research into which methods are what for, I've come around the topic "Backend Operation Proxy" (BOP). To be brief: The major recommendation seems to be, to use a BOP for third party (non-SAP) data providers which provide some kind of API via, let's say, a Webservice.
Now, there is a method CREATE_WS_BOP in the Facade-Class which makes sense to me according to my aforementioned research results. However, there also is a method CREATE_RFC_BOP, I assume, obviously, for RFCs.
What makes me wonder and what I haven't been able to find out yet is, whether there is any situation in which the usage of BOPs is sensible when retrieving data from another SAP System or, put differently, I don't (yet) see any difference between an RFC-BOP from SAP-System A to SAP-System B and a simple Remote CALL FUNCTION, except for X more wrappers around the BOP and the actual RFC-Call.
Deriving from my research results, so far, I would go for a simple CALL FUNCTION and leave the BOPs alone, unless somebody can explain to me that there are advantages to using a BOP instead of a direct RFC-Call that I currently don't know of or have not yet been able to figure out.
Cheers, Lukas
I am looking for the same explanation. I have a migration from Gateway system to S4 hana system. We have a custom task provider service on Gateway. It is implemented using BOP where the data was actually coming from ECC system. So made sense. Now that we are migrating to S4 (where the data actually resides), it is necessary for a BOP in a custom task provider service implementation. Anyone could suggest the best practise for this please?

Hello,
What TCM-compliant OData service?
