Hi Rala,
Few things to proceed further:
What is the document splitting characteristics, as in my case splitting is based on Busienss area.
It seems in your case the splitting is based on characteristcs Fund type. If possible may I request you to share the screen shots of the characteristcs.
I have attached the doucment which shows the list of steps required for configuring document splitting and activating the same.
Let me know for further information.
