To ensure that the partners involved in a message can be unambiguously identified in a defined process, corresponding identifications must exist in the messages. Exceptions are Channels with established partners.

The identification of these partner identifications depends on the message type. With EDIFACT, AnsiX12 or other (standardized) messages, it is clearly defined by the corresponding data elements

Note: For correct partner recognition, valid settings for Analysator and Recognition component ¹⁾ of the Repositorium are necessary.

In the EDIFACT UNB ²⁾ segment, sender and recipient of the message are defined.
As a rule, the GLN / ILN is used for this purpose in Germany and is indicated with the qualifier 14 . Example:

 UNB + UNOB: 2 + 4399901889996: 14 + 4032055000007: 14 + 170404: 0920 + 37108006 '

The Analysatoren is set here at Partner recognition = By Interchange address and in the Recognition component at recognizer type = eBiss.ClassLib.Analyzers.EdifactTypeRecognizer .

Alternatives to the GLN are possible and can be determined with the corresponding Quailifieren.

Examples

• eGate Participant number with qualifier 53
• Telephone number with qualifier 12
• own ID with qualifier ZZZ

That means, these IDs must be created as Edifact UNB Communication addresses in the system, or trading partner.

In the case of customer-specific objects, this is preferably set in the Object definitions with corresponding Data type attributes³⁾.

In the following example, the headquarter GLN is used in the path EDI_InvList / CustInvoiceJour / CustTableInvoice / EDI_GLN .

Note: Instead of using the data element attributeMapListType(typeof(…))] the LIST class is used, since it allows to read the first element with the method FirstOrDefault ()

Note: The Setting Recognition component is very flexble and allows for all possible identification features, which are saved under Backend-Reference, GLN, TNr or Communication addresses ⁴⁾.

For this variant, detection within the message can be dispensed with. However, then a corresponding channel is dedicated only for a combination transmitter-receiver possible.
