Pending Edit Alerts
Pending edit alerts are informational messages explaining that a transaction
that has ―state‖ information (that is, internal buffers that contain information
about the current and previous states of the transaction) will lose that state
information. The conditions necessary for a transaction to be reset are
described in detail below.

Some transactions require state information to execute correctly. If you
make certain changes to these transactions or the bindings they use, the
transaction resets or behaves as though it is starting for the first time when
you assemble the pending edits. FactoryTalk Transaction Manager warns
you that the transaction will be reset by displaying a pending edit alert
message. If the transaction includes any of the following characteristics, it
requires state information.
 Ignore First Unscheduled Event.
 Transactions Stores Data On Number of Completed Transactions.
 Transactions Stores Data On Data Change and/or Rate.
 Expression using DIFF function.
 Expression using Data Point Range function used in conjunction with
the Min, Max, or Avg functions.
A pending edit alert occurs if your enabled transaction includes any of the
characteristics listed above and you perform any of the following tasks or
change any of the transaction parameters:
 Trigger type.
 Unscheduled event data point trigger.
 Add a binding.
 Delete a binding.
 Data point to expression.
