Filter Related Problem into Qlik

[Anonymous]

if i have two table- Table1 and Table2 and i have filter condition just like as --- Table.1cust_id=123 and Table2.cust_name='Abhijit' or Table1.cust_id<=4567 and Table2.Cust_name='JOHN'.So, in this scenario, how can i write the load script editor into qlik.

Here , i also used Qualify, unqualify  Syntax

Qualify*;

Unqualify Product_id;

Load  *

From lib://'connection'/Table1.qvd (qvd);

Load *

From lib://'Connection'/Table2.qvd (qvd);

So, my question , where i will use this filter condition.
