Linkage table between interaction record and service ticket.
I have a service ticket and an interaction record created fro the corresponding service ticket. In my badi I get the interaction record guid. From this guid i need to fetch the corresponding service ticket (which is the parent). CRM_DOC_FLOW_READ_OB is not of any use for me since i have my child data i.e interaction record and I need to get the parent .
Please suggest a solution.
