Pass field value from Request to Response Mapping, without BPM in PI 7.11

Hi Experts,

I have a requirement to pass (store & retrieve) the value of a Field from Request Mapping to Response Mapping. I am not using any ccBPM and Client doesn't want that approach. My version of PI is 7.1 EHP 1 SPS 11.

Can I use the below Blog solution by Praveen  without BPM?: Usage of Dynamic Configuration in Synchronous Scenarios

I would not be able to use the blog by Beena Thekdi

Insert value from Request message to Response message using GetPayloadValueBean and PutPayloadValueBean

and by Praveen"PutPayloadValueBean" - not only for Synchronous Communications !! as they are only available with 7.3.

Please let me know if you think there is any other way to avoid BPM and implement this requirement in PI 7.11

Regards,

Nabendu.
