Suppose the input is:

ri!data: {

a!map(id: 1, name: "John", city: "Delhi"),

a!map(id: 2, name: "", city: "Mumbai"),

a!map(id: 3, name: "Priya", city: "Pune"),

a!map(id: 4, name: null, city: "Hyderabad")

}

Step 1 — Loop through each record

a!forEach(

items: ri!data,

expression: ...

)

How it works

Processes one record at a time.

Step 2 — Check if the name exists

if(

a!isNotNullOrEmpty(fv!item.name),

fv!item,

""

)

How it works

If the name field contains a value, keep the entire record.

Otherwise, return an empty string.

Intermediate result:

{

a!map(id: 1, name: "John", city: "Delhi"),

"",

a!map(id: 3, name: "Priya", city: "Pune"),

""

}

Step 3 — Remove empty values

reject(

a!isNullOrEmpty,

...

)

How it works

reject() removes any value for which a!isNullOrEmpty() returns true.

It removes:

""
null
Empty lists

After removing the empty strings:

{

a!map(id: 1, name: "John", city: "Delhi"),

a!map(id: 3, name: "Priya", city: "Pune")

}

Final Output

{

a!map(id: 1, name: "John", city: "Delhi"),

a!map(id: 3, name: "Priya", city: "Pune")

}
