Need to filter out few elements from an array of dictionary

Use the expression part of a!forEach to construct a dictionary for each matching item.

expression: if(
  fv!item.department = "EEE", 
  {
    id: fv!item.id,
    name: fv!item.name
  },
  {}
)

Mike is absolutely correct - that's the right way to do it. But one additional suggestion (if you're on 20.3 or later) is to use the a!map() function instead of reconstructing a dictionary. The map is basically the same as a dictionary except it doesn't break if you try to use dot notation and the field doesn't exist, so I've found that I prevent a lot of annoying bugs by using a map instead of a dictionary!

Here's an example using Mike's suggested expression:

expression: if(
  fv!item.department = "EEE", 
  a!map(
    id: fv!item.id,
    name: fv!item.name
  ),
  {}
)

oh right, i keep forgetting where the good places are to use a!map, like here.

Thank you very much Peter

Thank you very much Mike really
