piyusha6151, You need to index the data as it is a non-scaler type. I have modified Chris' code and attached it below. Try using it..

a!localVariables(
  local!data: a!entityData(
    entity: cons!COE_DS_SAMPLE,
    data: {
      {id: 1, name: "test 1"},
      {id: 2, name: "test 2"}
    }
  ),

  a!forEach(
    items: local!data[1].data,
    expression: {
      /* each data set can be utilized here */
      fv!item
    }
  )
)

Something like below?

In entityDataPV rule input, i used the below code.

a!entityData(
  entity: cons!UAS_DSE,
  data: {
    'type!{urn:com:appian:types:UAC}UAC_UAS_Onboard_Data'(
      uniqueassetid: 1,
    ),
    'type!{urn:com:appian:types:UAC}UAC_UAS_Onboard_Data'(
      uniqueassetid: 2,
    ),
    'type!{urn:com:appian:types:UAC}UAC_UAS_Onboard_Data'(
      uniqueassetid: 3,
    ),
    'type!{urn:com:appian:types:UAC}UAC_UAS_Onboard_Data'(
      uniqueassetid: 4,
    )
  }
)

could you please show the structure of your entityDataPV? what type of value it contains we want to see that.

in my process, Process variable is entitydata type and contains entity value and data (multiple).

Now if i configure the above way then getting-

a!localVariables(
local!data: ri!entityDataPV,

a!forEach(
items: local!data.data,
expression: {

fv!item
}
)
)

Cannot index "data" because it is an array type (List of variant). Only fields with scalar types can be indexed from an array

deepakg's example is essentially it, here's the same just with a specific Entity Data type utilized. What are you doing with the data? Passing it where?

a!localVariables(
  local!data: a!entityData(
    entity: cons!COE_DS_SAMPLE,
    data: {
      {id: 1, name: "test 1"},
      {id: 2, name: "test 2"}
    }
  ),
  
  a!forEach(
    items: local!data.data,
    expression: {
      /* each data set can be utilized here */
      fv!item
    }
  )
)

That didn't help as process is receiving process variable of entity type. As per your example, issue is to get data part of local!data

Could you please try the below Code.

a!localVariables(
  local!data: a!map(
    entity: "Some Entity",
    data: { { id: 1, name: "ABC" }, { id: 2, name: "DEF" } }
  ),
  a!forEach(
    items: local!data.data,
    expression: {
      entity: "Some Entity",
      data:fv!item
    }
  )
)
