This feature lets you establish the maximum time allowed for processing the on-hand entries cleanup job. If the job doesn't complete before the specified number of hours, it will save the work completed so far and then exit. This capability is especially relevant for implementations that have high inventory usage, in which case you should schedule the job to run at times when the system is as lightly loaded as possible. Enter a value of "0" (or leave blank) to allow the batch job to continue running until it has finished.
