An integration object map is the top-level data map specifying mapping from one integration object to another. An integration object map contains one or more integration component maps and can optionally contain integration map arguments.
Data maps can be parameterized using integration map arguments. Map arguments can be referenced in any expression, including the integration field map expression, source search expression, precondition expression, and postcondition expression. For example, you may want to have a field map that creates an Order Number in the target object by prefixing the Order Number in the source object with a constant.
You may want to use this map for orders coming from multiple partners and use a different prefix for each partner. To achieve this with a single data map, you can define an argument Prefix in the Integration Map Argument List, and use this argument Prefix in the field map source expression: [&Prefix]+[Order Number]. Then in the input method arguments in EAI Data Mapping Engine business service, you can specify any value for Prefix.
