Consider giving this enhancement a thumbs up which addresses your issue.
In order to do this, you will have to loop over each of the time periods and then display the errors in the Information boxes.
As an example may look like this:
Dim failedItemList As New Text.StringBuilder()
Dim isFailedCount As Integer = 0
args.ConfirmationRuleArgs.Info4 = String.Empty
args.ConfirmationRuleArgs.Info4 = "Pass"
Dim assignedEntityName, periodDesc As String
Dim assignedEntities As List(Of WorkflowProfileEntityInfo) = _
BRApi.Workflow.Metadata.GetProfileEntities(si, si.WorkflowClusterPk.ProfileKey)
Dim wfTime As String = BRApi.Workflow.General.GetUserWorkflowInitInfo(si).SelectedWorkflowView.Year
Dim timePeriods As List(Of MemberInfo) = _
BRApi.Finance.Metadata.GetMembersUsingFilter(si, "Time", "T#" & wfTime & ".Base", True)
For Each assignedEntity As WorkflowProfileEntityInfo In assignedEntities
For Each period As MemberInfo In timePeriods
assignedEntityName = assignedEntity.EntityName
periodDesc = period.Member.Description
Dim cell As Decimal = api.Data.GetDataCell( _
"E#" & assignedEntity.EntityName & ":T#" & period.Member.Name & _
":C#Local:V#YTD:A#BalSheetAccts:F#Top:O#Top:I#Top" & _
":U1#Top:U2#Top:U3#Top:U4#Top:U5#Top:U6#Top:U7#None:U8#None" _
).CellAmount
If cell <= -1.00 Or cell >= 1.00 Then
args.ConfirmationRuleArgs.Info4 = "Fail"
failedItemList.Append( _
"E#" & assignedEntityName & " T#" & periodDesc & " Amount: " _
& Math.Round(cell,2).ToString & Chr(13))
isFailedCount += 1
End If
Next
Next
args.ConfirmationRuleArgs.Info1 = "Failed Items: " & Chr(13) & failedItemList.ToString
args.ConfirmationRuleArgs.DisplayValue = isFailedCount
'Process the pass/fail flag
If args.ConfirmationRuleArgs.Info4.Equals( _
"Fail", StringComparison.InvariantCultureIgnoreCase) Then
Return False
Else If args.ConfirmationRuleArgs.Info4.Equals( _
"Pass", StringComparison.InvariantCultureIgnoreCase) Then
Return True
End If
