If you want to obtain certainty about the use of a mapping function, you can proceed in the same way as described under Where-used list for mappings.

Note: Mapping functions can be used in mappings as well as in job definitions ¹⁾. For the search for complex expressions, special characters ²⁾ must be correctly escaped.

As an alternative to the content search in eBiss Dump files, you can also search directly in the database.

DECLARE @find VARCHAR(70)   
--SET @find =  '$SerialShippingContainerCode';
SET @find =  'SG_16/RFF/DG_C506[[]@DE_1153=''VN'']/@DE_1154';
 
SET @find = CONCAT('%',@find,'%');
 
WITH Mappings AS (
    SELECT (SELECT Name FROM  [Node] WHERE Oid = Node_oid) AS Node, Name, CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), [MapBytes])) AS MapDefinition
    FROM [MapDef]
)
SELECT Node,Name FROM Mappings WHERE MapDefinition LIKE @find;

DECLARE @find VARCHAR(70);
 
SELECT @find = 'Order Outbound';
 
SET @find = CONCAT('%',@find,'%');
 
WITH Jobs AS (
    SELECT (SELECT Name FROM  [Node] WHERE Oid = Node_oid) AS Node, Name, CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), [JobBytes])) AS JobDefinition
    FROM [JobDef]
)
SELECT Node,Name FROM Jobs WHERE JobDefinition LIKE @find;

Note: Mapping functions also apply to job steps that support the specification of Expressions³⁾.
