Using Auto Trim
Instead of activating map components manually, you can use the Auto Trim feature to modify the EDI side of the map according to a sample EDI file that you select (you must have previously created this EDI file).
The Auto Trim feature examines the EDI file that you specify and then activates and deactivates map components on the EDI side of the map, so that the two files match. The sample EDI file must be the same standard, version, and transaction set (message) as the map for Auto Trim to match map components.
To use Auto Trim, you must define the Segment and Element Delimiters. If you do not supply the Tag Delimiter, the system substitutes the Segment Delimiter. If you want to use composite elements, you must specify the Sub Element Delimiter. If you want to use release characters, you must specify the Release Character. See Verifying EDI Delimiters for more information.
The sample EDI file must be compliant and must not contain envelope segments.
Use the following procedure to use Auto Trim:
