problem one input record causes two output records

I have this situation where mapping an element  from my input record results in two outputs.

It appears to be a function of looping even though there is only on record input

record structure Occurrences

              zinvoice   min  0  max 1

                 invoicestruct  min 0  max *

              tmp_RECORD min 0  max *

             TMP      min 1   max  1

 I am mapping

ALE.zwalasn.z1invoiceStruct.belnr to <TMP TMP_INVOICE

input record

  <ALE.zwalasn.e1edl20Struct.z1invoice>

– <ALE_zwalasn_z1invoiceStruct>

  <ALE.zwalasn.z1invoiceStruct.belnr>0090643774</ALE.zwalasn.z1invoiceStruct.belnr>

  </ALE_zwalasn_z1invoiceStruct>

  </ALE.zwalasn.e1edl20Struct.z1invoice>

output

<TMP_RECORD>

  <TMP TMP_INVOICE=”0090643774″ />

  </TMP_RECORD>

– <TMP_RECORD>

  <TMP TMP_INVOICE=”0090643774″ />

  </TMP_RECORD>

I don’t understand why in the biztalk mapping process, it wants to output two TMP_Records especially when there is only 1 input field ( ALE.zwalasn.z1invoiceStruct.belnr)

I have tried multiple combinations of the min and max occurrences to no avail.

No matter what I try it seems to want to output 2 output records

Any help will be appreciated
