Hi,
Thanks for the details. This is really good information to do some error analysis.
I was able to fix my issue. I checked SMHF standard one was also working fine and Normal change standard and custom both were also working fine.
Only the issue was coming up with ZMHF transaction it was getting created and when I try to change the status to "In Development" it was giving error message not associated with active task list. That time I realized that I had changed
SPPFCADM action definition ZMHF_ACTION for ON_SAVE to trigger the email functionality I had deleted the method call and add smart form. That was causing the issue.
I added the user_status = E0001 in ON_SAVE and cleaned up the inconsistencies and after that I tried it worked fine.
My assumption was SPPFCADM action definition & condition will be mostly used for triggering emails but it influence more than that.
Thanks
Junaid
