There is no way for us to know from the limited information you supplied. You only showed text from some message, but you didn’t give us the message ID. The text refers to a different message that has message ID CPF0001, but you didn’t show that message to us… and that one is probably about the real error. — Tom
Thanks! I did figure this out to be a parameter not passed correctly.
Whenever error conditions are asked about, the error text is useful but the message ID is almost required. In many cases, different Message IDs can have the same text but different causes. A “function check” message generally shows up when some inner ‘function’ had a failure and there was no handling of that failure. Most likely, the function check message ID was CPF9999. — Tom
