About Key Field Matching
Input records support the standard Sterling B2B Integrator Map Editor key field constant and code list matching. Additionally, Sterling B2B Integrator Map Editor enables you to match against fields that appear previously in the map. If you want to match against a previously mapped field, you can have up to three key fields.
If you are mapping from a join of master-detail records to an equivalent hierarchy, the translator can determine when the keys in the detail level no longer match the keys in the master level.
Note: Key fields are intended to be used with string
fields only. If you use a key field on a numeric field, the result
is not guaranteed.
