How get the value from a dictionary?

You can use the fn!index() and use the 'name' of the name/value pair (rather than the index number) as if you were asking it to search the dictionary e.g. fn!index(<myData>,"estadopedido", null). Note that the third parameter is what will be returned if the search does not find what you've asked for. Here's an example:

a!localVariables(
  local!myDictionary: {
    item: 1,
    description: "Widget",
    color: "Green"
  },
  fn!index(local!myDictionary,"color",null)
)

returns:

a!localVariables(
  local!myDictionary: (index(a!queryEntity(
    entity: cons!GP_Pedido_Entity,
    query: a!query(
      selection: a!querySelection(
        columns: {
          a!queryColumn(
            field: "estadopedido"
          )
        }
      ),
      logicalexpression: a!queryLogicalExpression(
        operator: "AND",
        filters: {
          a!queryFilter(
            field: "nombrepedido",
            operator: "=",
            value: ri!nombrePedido
          )
        },
        ignoreFiltersWithEmptyValues: true
      ),
      pagingInfo: a!pagingInfo(
        startIndex: 1,
        batchSize: -1
      )
    ),
    fetchTotalCount: false
  ).data,1))
  ,
  fn!index(local!myDictionary,"estadopedido",null)
)
