Add an Expression transformation to the mapping, between the source and target objects.

Link all the ports from the source object to the identical ports in the Expression transformation. For example, if your topic table includes the column

EMPNO

, link the

EMPNO

port in the source object to the

EMPNO

port in the Expression transformation.

Configure the following additional ports in the Expression transformation:

Link all the ports from the Expression transformation to the identical ports in the target object. For example, link the

EMPNO

port in the Expression transformation to the

EMPNO

port in the target object, and link the

DXPublicationInstanceID

port in the Expression transformation to the

dih__PublicationInstanceID

port in the target object.

Save the mapping.
