Create / delete links between entities ($links) in gateway

Hi experts,

Is it possible to manipulate (DELETE, CREATE) links between entities in gateway?

The documentation is somewhat contradictory:

Note 1574568 clearly mentions that it is not supported (General Constraints, point 7)

However, this document: /IWBEP/IF_MGW_APPL_SRV_RUNTIME - SAP Gateway - SAP Library mentions 2 methods in interface  /IWBEP/IF_MGW_APPL_SRV_RUNTIME: CREATE_LINK and DELETE_LINK

We are running SAP_GWFND SPS13 and these 2 methods are not available in our system. A 'method not implemented' exception is raised in our GW hub system when we try to execute a DELETE on a $link.

Are there plans to support this functionality? As of which release?

Best Regards,

Thomas
