In LityxIQ, you can very easily make a copy of a dataset definition. This process does not create a copy of the data, just a copy of the settings for a dataset. You can use this copy as a template for creating a similar dataset that is, say, based on the same data or data dictionary, or making an exact duplicate of the data. Follow these steps:
1) Select the dataset you wish to copy in the Available Datasets list (it will highlight orange), and click Copy Dataset Definition in the Selected Dataset menu.
2) Give a name and description (optional) to the copied version of the dataset. Optionally, you can also select a different library in which to place the newly copied version of the dataset. When finished, click OK.
