From mappings menu select create

Enter the mapping name (m-simple pass) click ok

• From source sub folder drop the source definition (emp) to the mapping designer work space
• From the Target subfolder drop the target definition (dim-employee) to the mapping designer work space.
• From source qualifier(SQ-emp) the columns with the corresponding columns in the target with simple drag and drop operation.
• From Repository menu click on save
