Update a field based on indexing

a!localVariables(
  local!Y: {
    a!map(id: 1, name: "test5"),
    a!map(id: 4, name: "test6")
  },
  local!X: {
    a!map(id: 1, name: "test1"),
    a!map(id: 2, name: "test2"),
    a!map(id: 3, name: "test3"),
    a!map(id: 4, name: "test4")
  },
  a!update(
    local!X,
    wherecontains(local!Y.id, local!X.id),
    local!Y
  )
)

-------------------------------------------------------------

a!localVariables(
  local!Y: {
    a!map(id: 1, name: "test7"),
    a!map(id: 4, name: "test8")
  },
  local!X: {
    a!map(id: 1, name: "test1"),
    a!map(id: 2, name: "test2"),
    a!map(id: 3, name: "test3"),
    a!map(id: 4, name: "test4")
  },
  a!update(
    local!X,
    "name",
    a!update(
      local!X.name,
      wherecontains(local!Y.id, local!X.id),
      local!Y.name
    )
  )
)

It can be achieved multiple ways. use Wherecontains() to index based on id

thanks for the reply, is there a way , I can do this inside a button. my requirement is upon button click , I need to update.

you can use the same what Venkat has mentioned in the buttons saveInto parameter.

a!save(target: local!data,value: a!update()) 

tried this, but local!data lost rows with id 2 and id 4, because we are saving only two updated rows into this variable)

Yeah Update returns the result.. So need to careful with what you are indexing. Have a look into the below template

a!localVariables(
  local!Y: {
    a!map(id: 1, name: "test5"),
    a!map(id: 4, name: "test6")
  },
  local!X: {
    a!map(id: 1, name: "test1"),
    a!map(id: 2, name: "test2"),
    a!map(id: 3, name: "test3"),
    a!map(id: 4, name: "test4")
  },
  {
    a!buttonArrayLayout(
      buttons: {
        a!buttonWidget(
          label: "Button",
          style: "OUTLINE",
          saveInto: a!save(
            local!X.name,
            a!update(
              local!X.name,
              {
                wherecontains(
                  tointeger(local!Y.id),
                  tointeger(local!X.id)
                )
              },
              { local!Y.name }
            )
          )
        )
      },
      align: "START",
      marginBelow: "NONE"
    )
  }
)

works perfect for local variable , but for record type , it throws error a!localVariables(
local!Y: {
a!map(id: 1, name: "test5"),
a!map(id: 4, name: "test6")
},
local!X: a!queryRecordType(
recordType: 'recordType!{a765be9a-3396-4105-8e82-56074696a931}LMS Test',
fields: {},
pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 100
)
).data,
{
a!buttonArrayLayout(
buttons: {
a!buttonWidget(
label: "Button",
style: "OUTLINE",
saveInto: a!save(
local!X['recordType!{a765be9a-3396-4105-8e82-56074696a931}LMS Test.fields.{74a22d07-4f83-4cc6-b8e8-1d3ff4bb620e}name'],
a!update(
'recordType!{a765be9a-3396-4105-8e82-56074696a931}LMS Test.fields.{74a22d07-4f83-4cc6-b8e8-1d3ff4bb620e}name',
{
wherecontains(
local!X['recordType!{a765be9a-3396-4105-8e82-56074696a931}LMS Test.fields.{0804dc2d-19ac-41c7-aee2-cae30a26dd96}id'],
tointeger(local!Y.id)

)
},
{ local!Y.name }
)
)
)
},
align: "START",
marginBelow: "NONE"
)
}
)

error :

Wrap it inside tointeger() and isn't it in reverse?? You want to update local!X  and update why you are giving direct record field reference??

a!update(
local!X[record.name],
wherecontains(tointeger(local!Y.id),tointeger(local!X[recordname.id])),
local!Y.name)

a!update(

Thanks it worked
