I am sharing common issues faced while implementation of charm in SP12.
1. Normal change had status "In development" if it created from the RFC.
ZMMJ_ON_CREATE_MJ : Define the statuf value in the condition for this action.
2. Partner id is not visible in Charm approval procedure even after creating the policy.
You need to create the rule moduler profile and assign it here.
go to Service manager profiles
Copy as this profile in your own name
Give the service id as SRV_REQ_RULE_EXE
In the properties tab, assign the policy that you had created in rule policy through web ui
3. while extending the scope, release for approval is not visble.
Check the action release for approval and insert the status value and set the maximum value accordingly in the action defination.
Hope it will be helpfull.
