Hello @vinuth v ,
Understanding reference qualifiers for variable is pretty simple.
Simple : Filter outs records which are being returned from the reference table. It is more like an encoded query where you just apply a filter on a table.
Dynamic : Instead of making your query static, you can pass dynamic values to it and filter the records that are being return from reference table. Please check below example.
"location="current.variables.loaction //Passing location value dynamically from the catalog form
Advanced : Here, you can actually write a function or any server side logic to filter your records. Please see below example.
javascript: new myScriptInclude.myNewFunction(); // calling script include function which will return sys_id of filtered records.
