Hi,
how can I, in runtime, log a pipeline field into the audit database as the platform does for those fields set as ‘Logged Fields’. Is there a service doing this?
Thx,
Bruno
review the documentation:
webMethods Audit Logging Guide
I think the Service Log should give you some help.
It can save the pipeline when the service start.
If you want to save certain field in the middle of the service, you have to create some code of your own.
If I got you correct 
can you check the flow service properties enable auditing… see if that helps…
