Attach spool in Mail type job Definition?

Question

Below is my case:
Job chain: AAA
Step 1, Job 1 : run Generic WHT report
Step 2, Job 1 : a custom Mail type job Definition
Tried below expressions to attach spool all failed, only can capture the log texts..
[Attachments]
spool.txt=Step 1, Job 1:spool
spool.txt=Step 1, Job 1:step1/spool.txt
spool.txt=Step 1, Job 1:step1/spool1.txt
spool.txt=Step 1, Job 1:?type=txt
spool.txt=Step 1, Job 1:?type=spool
spool.txt=Step 1, Job 1:?type=txt
spool.txt=Step 1, Job 1:spool
spool.txt=Step 1, Job 1:*
spool.txt=Step 1, Job 1:?type=*
I was able to attach spool file using System_mail_send.
Relative Job -  Step 1, Job 1
Job file    -  step1/spool1.txt
Really hope someone can provide advice..

Answer 1

Can you please try the following?
#Attach all files from Step2, Job 1
@{name}-@{index}.txt=Step 2, Job 1:*
Also have you set the registry key mentioned in admin guide to set permission for mail job to access the output files?
For security reasons, you have to specifically allow the directories in which the files reside on the server to be able
to attach them. This is done by setting a key below configuration/mail/AccessiblePath in the registry.
The registry key does not exist by default and needs to be created. For example, C:\temp could be the value of
the registry key configuration/mail/AccessiblePath/temp, note that the name temp of the registry
key has no significance to SAP CPS, it is its value that will be used.
Also, what version of SAP CPS are you using?
Are you receiving the mail, but without attachments?
thanks
