Hi venky,

I want to promote only class 8 student to 9

when I try below code it is updating all the students.

a!localVariables(
local!a: {
a!map(name: "X", class: 5, School: "ABC"),
a!map(name: "Y", class: 6, School: "ADC"),
a!map(name: "Z", class: 7, School: "AEC"),
a!map(name: "K", class: 8, School: "AFC")
},
a!forEach(
items: local!a,
expression: a!update(
data: fv!item,
index: "class",
value: 9
)
)

)

Thanks in Advance
