hello @parth.parmar, welcome to the Tulip Community!! it’d be great if you could introduce yourself at: Welcome to the Community, let's meet!!
thanks for posting your question, I’m also looking forward to reading suggestions regarding how others have connected to SAP from Tulip.
I will mention that we have a Unit Test Library App specifically designed to connect to SAP (S/4 HANA): SAP S/4 HANA Cloud Unit Test | Operations App Library | Tulip. while this App doesn’t make use of the middleware you suggested, it may be a good starting point to get some inspiration.
again, welcome to the Tulip Community!!
