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

[nabendu_sen]

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   without BPM?:

I would not be able to use the blog by

and by 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.

Hi Nabendu,

Since your PI version is 7.1 EHP 1 SPS 11, may be you can also consider this custom module solution blog by Roger Allue: which is equivalent to PI7.31 ehp1 feature new modules

Hi Praveen,

My first preference would be handling this requirement in Mapping. Otherwise I will go for Adapter Module.

I am still working with "DCUsage.com" as per your blog. Only concern I have this to make the namespace unique, otherwise if 2nd message comes before completion of the first, it would be messed up.

Sorry, I am not sure if I have understood your point. I hope each synchronous message is independent (transaction) and hence having a fixed namespace for custom DC shouldn't be an issue

Hi Praveen,

Does that mean each individual Synchronous / Asynchronous message has its corresponding DCUsuage space and there could not be any conflict?

Suppose 1st Message completes its Request Flow, stored values in DCUsuage and gets stuck. Now 2nd Message comes after that and it completes Request as well as Response. If now 1st Message Response tries to retrieve value from DCUsuage, it would be the value which was set at 1st Message Request.

So there would be no conflict because 2nd Message could never access 1st Message's DCUsuage.

All messages have their own separate DCUsuage.

Am I correct?

Hi Nabendu,

Exactly, your understanding is right. In general, each message is independent (a separate transaction)

Hi Praveen,

It worked successfully and we almost in the phase of testing completion. Thanks for your help.
