When running scripts that Set Field in a related file on the network, sometimes it works and sometimes it doesn't. I've captured errors, and it is 102: Field is missing. If I run the script twice, it might work once, and fail once. Or work twice. Or fail twice. Anyone have any idea why? The original file and the related file are on FMProServer5, and there are no problems with the network. Is it possible that more than one user are trying to change the same field at the same time? If so, is there a way around this?

Hi Rodhaden

I'm sorry I don't have a solution to your problem BUT, just as an answer to your last question, as far as I know, it is not possible for more than one person to be working on the same record at the same time over a network, I don't think FM allows this, so the answer must lie elsewhere. As I said, though, I am not 100 per cent sure about this. Sorry I couldn't be of any more help.

I would start by running your "Set Field" script in the related file itself, rather than in the other file. This should eliminate and kind of network, layout or relationship problems.

If it still fails after than point, hopefully giving a different error code, you could look into the possibility of these records being used by someone else.

The only real way around record locking is to setup some kind of system where you first check a flag field to see if the record is available, flag it as "in use", and then perform your operation, flagging it as "available" afterwards. Use a text (NOT global) field in the related file as the flag.

If the record is already flagged as "in use" your script could loop a while and keep checking, or could simply abort the procedure and inform the user that the operation failed.
