5.12.4 Parameter MappingLocate this document in the navigation structure

Use

For the parameter mapping, the following rules apply:

  1. The starting point is the set of parameters that are mapped.

    • All parameters that are mapped are filled.

    • Parameters, for which no input value is supplied, are stripped.

    • All static parameters are automatically forwarded.

  2. In the next step, the incoming parameters are evaluated.

    • All parameters used for mapping are discarded.

    • For all incoming parameters, for which a new value already exists, the incoming parameter is dropped.

    • The rest of the parameters are forwarded transparently.

Inbound Parameters

Mapping Table

Outbound Parameters

Comment

A=1

X={A}

X=1

X is filled with the value of A, A is discarded from the input set.

B=2

 

B=2

B is not referenced and mapped through transparently.
 

Y=3

Y=3

Y is statically defined in the mapping and automatically used as an outbound parameter.

Z=99

Z=4

Z=4

Z gets a new value from the mapping, which is used as an outbound parameter. The original inbound parameter is discarded.
 

Q={KLM}

(Q=)

For Q no value is supplied. It is discarded (effectively set as an outbound parameter with no value).
Note

The parameter mapping is done on string values; no processing is done to change the data format or representation of the parameters.
