How do I pass SELECT OPTIONS as input to AMDP methods?

You can't directly pass SELECT OPTIONS as input to ABAP Managed Database Procedures (AMDP) methods. A method called APPLY_FILTER must be used to filter based on selection screen input to avoid this limitation of AMDP. Below filtration shows the correct usage of passing SELECT OPTIONS as input to AMDP methods.
