Understanding EDI Cross References

When EDI data enters the system, the system uses the codes to identify the type and the frequency of the requirement. Requirement codes are standard within the EDI system, but their uses can vary, depending on each customer's business practices, as described in the table:

Customer	EDI	Requirement Type	Requirement Frequency	Actual Use
Customer 1	X.12	C	D	Firm Daily
Customer 1	X.12	D	D	Plan Daily
Customer 1	X.12	D	W	Plan Weekly
Customer 2	X.12	C	C	Firm Daily
Customer 2	X.12	D	C	Plan Daily
Customer 2	X.12	D	W	Plan Weekly
Customer 3	EDIFACT	1	D	Firm Daily
Customer 3	EDIFACT	4	D	Plan Daily
Customer 3	EDIFACT	4	W	Plan Weekly

To handle these differences, you must set up a cross-reference record for each requirement type and requirement frequency combination. This record specifies the demand type (firm or plan) and the frequency of demand (such as daily). The system processes the Demand Type and the Demand Period fields to determine the requirement.

You can set up cross references for all Branch/Plant and Sold To records, all Sold To records for a Branch/Plant, or for a specific Sold To record.
