Hi Surai You can't. What you can do is: 1. Run proc contents (proc contents data=<your sas dataset>;run;). If you're lucky then the creating program wrote in the dataset label it's name. 2. Get the properties on OS level and look who created or owns the dataset. Might give you a hint where to search or whom to ask for the code. 3. Search possible SAS source code for the name of this dataset. 4. Analyse Logs if available. Hope that helps Patrick
