This function identifies a partner channel that has an additional ID with name a and value b.

If the optional parameter d is set, the search will be restricted to partner channels of a certain type.

If e is true, the search will be restricted to active partner channels only.

Parameter c is then used in the found partner channel to return the value of another additional ID with the name c. If nothing is found, an empty string with set Empty Flag will be returned.

Parameters

Parameter	Description
a	Additional ID 1: Name.
b	Additional ID 1: Value.
c	Additional ID 2: Name.
d	(optional) Type of partner channel to restrict the search. Default: No restriction. Note: Use the three dots to select a value.
e	(optional) true if only active partner channels should be used. Default: false.

Examples

Assume two partner channels with the following attributes (simplified).

Partner channel ID	<Partner name>:<Channel name>	Partner channel type	Active?
1	Lobster:FTP	ftp	true
2	Lobster:AS2	as2	false

The following additional IDs are defined.

Partner channel ID	Name of additional ID	Value of additional ID
1	customerid	4711
1	accountno	12345
2	customerid	4712
2	accountno	23456

This will lead to the following results.

Parameter a	Parameter b	Parameter c	Parameter d	Parameter e	Result
customerid	4711	accountno	ftp		12345
accountno	23456	customerid	as2		4712
customerid	4711	accountno	ftp	true	12345
customerid	4712	accountno	ftp	true	(Empty string with set Empty Flag.)
customerid	4711	accountno	smtp		(Empty string with set Empty Flag.)

If you use a specific channel for a partner, you can save customer-specific values in its additional IDs. If you then get a customer-specific value in your input file (say the customer ID), you can use it to determine another customer-specific value (for example, the customer's bank account number).
