File to sync bapi_multimapping_without bpm

Question

Hi All,
I have done a file ->bapi -> response to file testing interface using the adapter modules.
My actual scenario is :
Source file has multiple lines and for each line i have to call a bapi. The response of the BAPI needs to be appended in a file.
My question is:
Should i use a BPM to call the bapi as many times as the lines present in the source file?
I read the sap documentation for multimapping and i suppose we cannot use multimapping for synchronous interfaces?
Is there any way i can do my scenario without using a BPM?

Bhavesh,
If you need to avoid BPM, then you have to change the BAPI / RFC to be able to take multiple records in one call.
How can i do this? Can you please explain?
I searched for blogs, but all of them i saw, have one rfc call. Is there any blog that does this without a bpm:
a) Source file comes in with multiple lines
b) For each line a sync bapi or rfc needs to be called
c) Reponse needs to be written to a file
I did my scenario using a BPM and the performance is very bad (the size of the box is small, but would not make a great deal of difference if it were a bigger box). Here is what i do in a BPM
1) get the source file
2) call bpm
  2.1) inside bpm, transformation1 - does a multimapping
  2.2) block start(For Each)
  2.3) Sync Send to bapi. Mapping called outside bpm in interface determination
  2.4) Async Send - to write response - done in the response mapping of the Interface Mapping.
Please let me know if i can do how i can do steps a, b, c (in bold above) without bpm
Thanks,
