Is there a LookupValue Function to retrieve Parent LIC Value

Hi Experts,

Is there a direct function to retrieve Parent LIC Value in eScript.

I have the following structure for example

LOV Type           Value             LIC       Parent LIC

Test                    Parent          Parent

Test                    Child1          C1        Parent

Test                    Child2          C2        Parent

Test                    Child3          C3        Parent    

I would to get a field value in Prewrite Record and check if the field value is present in LIC of Parent and Child (Parent, C1,C2,C3) in this case.

Any inputs are helpful.
