MSIR.0510 Cancelling request because of SIRFACT CANCEL ($func) (val)
A request is being cancelled because '$func' returned a value specified on a SIRFACT CANCEL '$func' command. Determine the cause of the bad return value from the $function (perhaps by getting a SirFact dump) and correct the User Language code, or if it is determined that 'val' should be an acceptable return value from '$func', remove the value from the SIRFACT CANCEL command or wrap the specific $function invocation in a SIRFACT OFF/SIRFACT ON bracket.
