Filtering by text in the messages

Reviewing transaction messages is a common use of the software. The "Message Type" pull-down is used to select only transactions and other messages that relate to transactions.
There are methods to filter transaction messages further by specific text contained in the messages themselves. This is performed by using the two text criteria input fields located above the "Reload File" button. In this example, the word "Credit" was entered into the Message Contains input field. Therefore only the credit card transactions were displayed for lane 3 within the date/time. The transaction messages were selected by the Message Type pull-down. In this case it was set to "T" rather than "All".
Filtering text Not in the Messages

It's also possible to "filter-out" messages by ignoring certain text. In this example, all messages containing the word "Cash" were filtered out by using the "Message Doesn't Contain" text input field.
The result is a list of non-revenue, no-funds, and violation transactions for lane 2 within the specified date/time range. All cash transactions were filtered out.
This type of filtering is useful to remove unwanted messages from the result list.
Filtering by a specific collector ID

In this example, all transactions for a specific collector are displayed. This includes all lanes in which the collector worked for the date/time range selected.
This is performed by using the pull-down for lane number and by entering the ID of the collector into the "Message Contains" text input field.
The search could be further restricted by filtering down to only one lane.
The types of transactions displayed are according to the messages produced by the system. In these examples there are three types of transaction messages. Each is identified by a colored "dot" to improve readability. The rows identified by yellow dots are classification messages which represent the vehicle class as entered by the collector. The rows identified by green dots are the transaction messages themselves. These arrive after the classification message at the time when the vehicle exits the lane. The rows identified with blue dots are summary Segment of Duty records. These are generated when the collector logs off, when a toll schedule change is made, or at midnight. Specific messages of course are dependent on the messages produced by the toll collection system.
