l Change the value of a property in the EDI structure. For example, error DDEE0004 indicates that a mandatory element was missing. One Quick Fix for this type of error is to change that element's Requirement property from Mandatory to Optional. This results in importing a local copy of the segment's definition to the SEF file and changing the element's Requirement property. This change affects the specific definition only and might be appropriate if you want to do validation in general, but in this specific context, you do not require a value for the element.
