Dealing with CPE3029 in CPYFRMIMPF

Does anyone have a good way of dealing with an error thrown by the Copy From Import File (CPYFRMIMPF) command:

Message ID . . . . . . : CPFA0D4
Message . . . . : File system error occurred. Error number 3029.
Cause . . . . . : File system experienced an unexpected error. Error number
3029 was received.

Error 3029 points to:

Message ID . . . . . . . . . : CPE3029
Message file . . . . . . . . : QCPFMSG
Library . . . . . . . . . : QSYS

Message . . . . : Resource busy.
Cause . . . . . : An attempt was made to use a system resource that is not
available at this time.
This occurs when the file is open elsewhere. The situation is that there are .csv files in the IFS that might be open in Excel. All the program is attempting to do is copy the data into a PF. It seems to want an exclusive lock. Is there a way to tell it not to require that level of a lock?

This is extra strange to me because other commands such as MOV or REN seem to work fine, even if the file is open in Excel. I think that those command *should* throw an error when the file is in use!

The original message is sent as a diagnostic message, so it can't be monitored. Only the final message: "CPF2817 Copy command ended because of error" is an escape message. This is a generic message for any error in this command. I can of course monitor the escape and then receive the previous message, but I was hoping for a more elegant solution. TIA.
