Write to Elimination Member (Origin)

Hi All - I have a quick question 

1. When I am using the Data Buffer, I am able to write to the Elimination Member.
2. The Same for the Set DataCell as well.
3. When I try to use the same in the Member Script Value it is not writing to the Elimination Origin except forms. Any Idea why ?

Below is an example

'                        strMemberScript = "Cb#Cube:E#100:C#Local:S#Actual:T#2022M12:V#YTD:A#123456:F#None:O#Forms:I#101:U1#None:U2#None:U3#None:U4#None:U5#None:U6#None:U7#None:U8#None"
'                                objMemberScriptValue.Amount = 100
'                                objMemberScriptValue.IsNoData = False
'                                objMemberScriptValue.Script = strMemberScript
'                                objMemberScriptValues.Add(objMemberScriptValue)

objXFResult = BRApi.Finance.Data.SetDataCellsUsingMemberScript(si, objMemberScriptValues)
