Issue

Batch Instance goes to error state with ConcurrentModificationException when executing the field change value script

 This is a known issue for Ephesoft versions prior to 4.5.0.0, in which very few scenarios the field value change script would run multiple times, putting the batch into error and throwing the ConcurrentModificationException. This has a low impact on batch instance processing.

To resolve this issue, upgrade to Transact 4.5.0.0 or above.
