Why set selection append flag has written more than one time

Hi guys,

Recently I got a chance to analyze the R42520 (Print pick slip) and I found in initialize section the SET SELECTION APPEND FLAG is written more than one time.

Below is the few sample code from that standard report.

********************************************************************************************************************************************************************************************************************************

Set Selection Append Flag(<Yes>)

// SAR - 8222089 - Initialize Variable

VA sec_cHasShippableLine_EV01 = "0"

// SAR 8222089 - End

// SAR 7749090 Start

// Reset the flag to zero

VA rpt_cPONxtStatusBlankFlag_EV01 = "0"

If PO szNextStatusFrom is equal to <Blank> Or PO szNextStatusCodeThru is equal to <Blank> Or PO szNextStatusFrom is equal to <Null> Or PO szNextStatusCodeThru is equal to <Null>

   VA rpt_cPONxtStatusBlankFlag_EV01 = "1"
