Message type: E = Error
Message class:  FI - TR-FM Funds Management 
Message number: 190
Message text: Program execution not possible: payment matching is active
You want to execute the program for the transfer of payments without
invoice reference (RFFMS201). This is not possible, as payment matching
for Funds Management is active in one of the FM areas.
To ensure error free payment matching, the payments without invoice
reference can, in this case, only be updated together with the payments
with invoice reference (RFFMS200).
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Execute the program for transferring payments with invoice reference
(RFFMS200). The selection screen for program RFFMS201 will then
automatically appear in program RFFMS200.
