SAP R/3(Client100 using Proxy)---- XI----- RFC(SAP R/3 client 222) Scenario

Question

Hi all,
I have the requirement to work on SAP R/3 ( with client 100 by using outbound Proxy)-->XI--->RFC(R/3 Client 222).
i have done IR & ID Part. Now i am going to create Report in R/3 side (100 client). But, it is synchronous, i am getting so much confusion. Please help me how to write the code for it.
The RFC is BAPI_EXCHANGERATE_GETDETAIL.
I created Request message, Response message for sender.
The message mappings are as follows:
For Request:
Sender Request------> BAPI Request
For Response:
BAPI Response---->Sender Response.
Interface mapping
Sender Interface---->BAPI.
Request message contains the fields:
Rate Type,
SourceCurrency,
TargetCurrency,
Response Message contains:
Exchange rate,
FactorFromRatio
FactorToRatio.
Please try to understand this requiement and help me to write code for this.
Thanks in advance.

Nagarjuna.

Hi Nagarjun,
If you look at the exporting and importing paramters of your Method EXECUTE_SYNC...
You would find the abap equivalent of your Message Type.  Hence you know all the fields.
No it depends on the business Logic, or ratheer what the RFC is suppose to be requested for is filled in an an Input paramter to the Method. 
This can be an IDOC To, in that case your MT should be similar.  Fill in the transmiaaion IDOC values.
OR you can Actually harcode the values, make your Itab, and send it across ( as this is just for test purposes )
Hope this helps.
