Gateway Service for FM with Importing tables

Question

Hello Experts,
I have a function module which imports around 4 parameters & a table with 4 fields. Since its a table, so there can be more than one entry. So, FM has:
Import Parameters - around 4 fields
Table  Parameters - a table with 4 fields. FM can execute more than one entry
Export Parameters - 3 fields - This is the information FM returns after processing records from import & table parameters
I am confused on how to build GW service for this scenario. I have gone through the GW service generation from FM but how are we going to address importing table parameter? I just need some pointers on how i should approach to build service for such a scenario.
Regards

Hello Ron,
Definitely it was inside-out modelling pitfall, but now, after going through your blogs & other such information on SCN, I am feeling better.
I myself prefer code based implementation since it provides lots of flexibility. FM constraint definitely limits the scope improvement.
we are developing a internal application where we are trying to replicate a existing old application which accepts data in adobe forms. Purpose of creation is to give application a UI5 look-feel & use the ODATA way of exposing & consuming services. So, this way we are learning & along the way, improving some internal applications as well. Of course, we are doing this by taking some time out of our PRIMARY work.
Reason why i wanted to use this FM was mainly because it was already available as its already being used in existing application. I was trying to figure out the possibility of using this FM without any logic tweaking.
I was exploring this possibility to create a service by keeping most of the code-related things intact from existing application. But you experts have been such a valuable advisors. I will do it the best way now.
Thanks a lot.
