I have $4$ tables in model$-$driven apps.

SA Customers

Customer Equipment

Assets entity view V$3$

Customers V$3.$

In SA Customers I have lookup column 'arb$\_$Customer' that looks to Customer V$3$ Table.

In Customer Equipment I have columns $-$ 'arb$\_$Customer' $($Lookup column that is looking to SA Customers table$),$ 'arb$\_$SerialNo.$\text{'}($Lookup column that is looking to the Assets entity view V$3$ table$).$

Assets entity view V$3$ table only has relation with Customer Equipment table but not with SA Customers.

The Serial no$.$ column in the form shows the Assets View and we want to filter this view based on the selected 'arb$\_$Customer' from the SA Customers table. Please give the whole JavaScript code for this issue.
