Short dump in RERAALCN - Accrual/Deferral: Contracts

Hi

I have configured to use deferral for RE-FX contract. It can simulate without error. However, upon posting to FI with execution mode, and when I click to drill down to FI document that it is posted, the system give short dump message.

Category: ABAP Programming Error

Runtime Errors: OBJECTS_OBJREF_NOT_ASSIGNED_NO

Except: CX_SY_REF_IS_INITIAL

ABAP Program: CL_REEX_ACC_SYSTEM_FI========CP

Application component: RE-FX-RA

However, when checking FB03, it has successfully posted to FI. Please help identify the cause of the program termination.

Thanks

Kai
