The cash letter tab provides summary information for each cash letter that is present within the currently loaded x9 file. Although most x9 files contain a single cash letter, there are implementations which use cash letters to separate and group items within an x9 file based on specific business requirements. For example, this x9 file may contain information which has been aggregated from other x9 files and where the original cash letters have been retained. For those situations, this summary is very useful since all columns are sortable, allowing you to quickly find any cash letter based on item count or amount. Error counters (error, warn, info) are provided which summarize the errors which were identified during validation. The summary includes the number of items and total amount. You can use the “line” column to resort into the original sequence. A “view” button is provided which allows you to drill down and launch to any cash letter within the x9 file.
