Node Function help required in XML message mapping !!

Question

Hi Brilliants,
Source Message
    <ROOT>               0..1   
      <OUTPUT>          0..n
         <Group_N1>           0..n     <Header>
            <H02_N1_DTM>                           0..1
      DTM_Y2K_DATE     0..1
         <Group_LIN>          0..n                <Lin Item>
     <Group_ZA>          0..n
          <D02_ZA>     0..n
      </OUTPUT>
</ROOT>
The above Source <OUTPUT> tag comes 2 times. In this two time, Header comes once per header and more than 50 times Lin item occurs.
Target Message
ProductActivityNotification                                                            0..n
     ProductActivity                                                       1..1
          Item                                                       1..unbound  (Lin Item level on target side)
             SalesTimeSeries                  0..1
                      Item                                           1..unbound
                    ValidityPeriod              1..1
                    StartDate              0..1
                    EndDate              0..1
The above source message Lin item, whatever the times it replicates, the same number of times u201CItemu201D tag has to occur and DTM_Y2K_DATE value has to pass to StartDate.
Could anybody please put your valuable idea on this? I suppose to deliver this interface tomorrow.
I will highly appreciate your intellectual ability.
Many Thanks in Advance
Kind Regards
San

HI San,
Based on your this post, i think u want like this way...
How many times from source  DTM_Y2K_DATE  or <LinItem>(because DTM_Y2K_DATE   in LinItem ) occurs that many of <Item> in target is required rt??
Then u map like,
DTM_Y2K_DATE  (Change context to LineItem(right clich and choose context)) and map  to LineItem of target.
and also now map directly from DTM_Y2K_DATE  to Start Date(Dont change any context now..)
If still nt clear do post..
