SAP PI 7.11 in NWA where can I change the property messaging.syncMessageRemover.removeBody

Hi the community,

We are in SAP PI 7.11.

I'd like to store synchronous messages.

To do this , I read I have to change the propoerty messaging.syncMessageRemove.removeBody  of service SAP XI AFD Messaging to false.

Can someone give me  to change that parameter in nwa (in which tab and hyperlink) ?

Best Regards.
