IDoc outbound errors - mail send step in WF to send info-mail to enduser

Question

Hello specialists
I searched quite a lot in the forums now. I found lot of info but nothing regarding my issue.
I need to send an info-mail to the end user creating purchase orders. But only if the idoc (outbound ORDERS) could not be sent (failing for some reason, i.e. if rfc connection fails). This is what I've done to achieve this:
- in WE40 I linked my WF to process code EDIO
- the WF-BATCH user has an email address assigned to it (in SU01)
- the mail sending step in my WF is configured like this:
recipient type = G (organizational object)
Expression = &_WORKITEM.CREATEDBYUSER.ID& (this contains the enduser id)
subject = Test for &WORKITEM.CREATEDBYUSER.ID&
When testing the mail can not be delivered (error SO23).
When setting recipient type to U (E-Mail address) and giving a valid e-mail address, then it works fine (SCOT, etc. is configured and mailing to external systems works). But setting the e-mail address hard coded style in the mail send step is not an option here!
It seems that the send mail step (SELFITEM.SENDTASKDESCRIPTION) always requires a valid e-mail address. Is it not able to handle SAP user id's ?
Thanks in advance for some guideance on this one.

Answer 1

Hello and thanks for your help.
I was able to solve it like this:
- don't use mail send step
- instead, add new activity with a new task (SELFITEM.SENDTASKDESCRIPTION)
- in the bindings (workflow -> step) set:
     B --> &TYPEID&
     &_WORKITEM.CREATEDBYUSER.ID& --> &ADDRESSSTRINGS&
Seems that the mail send step doesn't allow TYPEID to be "B" because each time I tried to tweak the generated bindings that way it messed up the recipient type and expression I set before.
