In Informatica once mapping is created and if we want to overwrite on the same mapping then we need to create a copy of that mapping as a backup. For creating a copy we need to use Copy as command. When we create a mapping using Copy as command then another mapping same as that of the original is created. This reduces the complexity in duplicating a mapping
To use the Copy As command to copy a mapping:
- Open a mapping in the Mapping Designer
- Click Mappings > Copy As.
- It will prompt for entering a new name. Enter a new mapping name
- Click OK.
