Deep Structure field in Read --Key Condition

Hi Experts,

I am having a query related to usage of a Deep structure table field field in my where condition.

Requirement:

I have a deep structure as follows

It have components as fieldname and domain values(which is a table type of DD07V table).

Now i have an internal(lT_values) table which have 2 fields like

Now I need to check whether this value exist in the DOMVALUE_L or in DOMVALUE_H.

For  that I looped the value table.

LOOP AT lt_values INTO ls_values.

READ TABLE lt_dom_val INTO ls_dom_val WITH KEY Fieldname = ls_details-fieldname  <xxx> = ls_values-values.

Am not able to access the DOMVALUE_L or DOMVALUE_H in the condition.

Kindly let me know how to reframe my Read table condition.
