Configure the mapping

Configure the mapping

To configure the mapping in this example, create a new mapping, and add a Java transformation. Then configure the source fields, target fields, and Java transformation fields. In the Java transformation, verify that the transformation behavior is active.
The following image shows the mapping:
The example mapping shows Source transformation "src_Emp" connected to downstream Java transformation "java_FindEmpMgr." The Java transformation is connected to Target transformation "tgt_EmpWithMgr."
Configure the transformations as follows:
Source transformation
In the Source transformation, update the source field metadata as shown in the following table:
Name
Type
Precision
Scale
Origin
EMP_ID
integer
10
0
<source file name>
EMP_NAME
string
100
0
<source file name>
EMP_DESC
string
100
0
<source file name>
EMP_AGE
integer
10
0
<source file name>
EMP_PARENT_EMPID
integer
10
0
<source file name>
Java transformation
The Java transformation includes all incoming fields from the Source transformation.
Create the following output fields:
Name
Type
Precision
Scale
EMP_ID_OUT
integer
10
0
EMP_NAME_OUT
string
100
0
EMP_DESC_OUT
string
100
0
EMP_PARENT_EMPNAME
string
100
0
On the
Advanced
tab, verify that the behavior is set to active.
Target transformation
In the target transformation, create the following target fields:
Name
Type
Precision
Scale
Origin
EMP_ID
integer
10
0
<target file name>
EMP_NAME
string
100
0
<target file name>
EMP_DESC
string
100
0
<target file name>
EMP_PARENT_EMPNAME
string
100
0
<target file name>
Configure the field mapping as shown in the following table:
Target Field Name
Mapped Field
EMP_ID
EMP_ID_OUT
EMP_NAME
EMP_NAME_OUT
EMP_DESC
EMP_DESC_OUT
EMP_PARENT_EMPNAME
EMP_PARENT_EMPNAME
