Function "F4311 Edit Line" doesn't write the record

Function \"F4311 Edit Line\" doesn\'t write the record

Hi,
I'm in trouble with this function (F4311 Edit Line), because sometimes it writes the record at the table F4311z and others it doesn't write it.
I modify the program to check if the conditions are acomplished to write the record, and everything seems to be o.k.
I built the package with the application and deploy it a lot of times and the problem continues.
Any ideas what should I do to solve the problem.
Thanks

do you see if the sql order is send (use the debug log).
We have a problem like this with the F4111 nd the XT411Z1.
We spent a lot of time to find than it was a problem of synchronisation. A cache's record was someone destroy before the F4111's updated. The exact of our trouble was the different of time's response on the production server and database server. We solve this by using a direct gigabit link beetween the two server.

Thanks for your answer.
I will check the speed between the servers.
