Hello Faseeh,
As per the screen shot its a nested structure.
I would suggest the below way of implementation as per best of my understanding :
For an instance lets assume you are sending Business_Partner Number say 10000 as input to get all the details of that particular Business_Partner which u have shared in the screen shot.
1. Create Parent Entity say BP_NUM which has the input Business_Partner Number.
2. Create Child Entity say BP_DETAIL which has got all the fields apart from PHONE , FAX & EMAIL tables.
3. Create Child Entity say PH_DETAIL which has got all the fields related for PHONE details of BP only.
4. Create Child Entity say FAX_DETAIL which has got all the fields related for FAX details of BP only .
5. Create Child Entity say EMAIL_DETAIL which has got all the fields related for EMAIL details of BP only.
Now Create Association and Navigation as follows :
BP_NUM to BP_DETAIL - 1 to 1
( assuming response of your FM will have one business partner as output and corresponding details for FAX, PHONE & EMAIL tables )
BP_NUM to PH_DETAIL - 1 to N
BP_NUM to FAX_DETAIL - 1 to N
BP_NUM to EMAIL_DETAIL - 1 to N
Implement Expand_Entity and pass BP Number as key ( assuming your FM will take a particular BP Number and returns all the details which u have shared in the screen shot ).
Refer the below for technical details.
Implementing Expand Entity/Entity Set
Create a deep structure and as a response return the corresponding tables accordingly by sending back navigation properties correctly to the expand clause.
