The SPOOLRECIPIENT is not sent to SAP by the agent. The agent AFM shows the values defined in the job.
Release : 12.0
Component : Workload Automation Agent for SAP
There was a change from SAP 4.6 version, due to which if commit work is not done explicitly, it does not process the email being sent to spool receipient
Following Agent param setting needs to be set in addition to a patch to send email via SAP instead of Agent:
sap.buffer.size.use_as_defined=true
sap.max.buffer.size.bytes=1048576 <Depending upon the size of the email content>
sap.office.use.documentSendApi1=true
sap.spool.recip_email=1
Patch can be downloaded here. This is for WA Agent R12 only.
