While creating Billing Document (VF01) on Dev. I am getting an exception CX_SY_DYN_CALL_ILLEGAL_FORM .
There exist various options:
Error in the ABAP Application Program
The current ABAP program "SAPLV60A" had to be terminated because it has
come across a statement that unfortunately cannot be executed.
Error in the SAP kernel.
The current ABAP "SAPLV60A" program had to be terminated because the
ABAP processor detected an internal system error.
What could be the problem ? Already Seached on SDN .
thanks in Advance
