FDM_GENERAL100 - Process step 003: Change not possible, process step 002 missing

Hi Team,

While executing FDM_PROCESS_BUFFER I am getting following error.

Process step 003: Change not possible, process step 002 missing

Message ID : FDM_GENERAL100

I have checked the status profile and looks good. also other dispute cases are getting closed successfully from the same status.

Now the AR items is cleared but Dispute case is still open.

Let me know how can I process further on this.

Regards,

Andy
