How to specify in Essbase rule file when loading metadata with parent\chil refrences to ignore for t

I have created a Rule File in Essbase 11.1.2.2 with parent child references with fields like this: Parent0, Product --- Child0, Product --- Alias0, Product and I have a source file where I have a long list of records where I need to ignore all parents who does not exist in outline and just add the products who have an existing parent in the outline, I have tried many options but every time I get all parents in the outlines and those who didn't exist are attached as children of the Product (dimension name)

Thanks,

Abde
