File to IDOC scenario : Error with mapping due to Context handling

Question

Hi Experts.
I have a file to IDOC scenario which need your advice.
Source File structure as follows:
Control_Header     <1:1>
Invoice_Header     <1:unbounded)
Invoice_Line          <1:unbounded)
Trailer                    <1:1>
Payload as follows capture from SXMB_MONI
- <Control_Header>
        <Key>999</Key>
        <TransactionID>RCTV</TransactionID>
  </Control_Header>
- <Invoice_Header>
    <Key>000</Key>
    <BusinessUnit>HDB05</BusinessUnit>
    <InvoiceNo>64471</InvoiceNo>  
</Invoice_Header>
- <Invoice_Line>
      <Key>001</Key>
      <UnitPrice>7.00000</UnitPrice>
      <Quantity>1.0000</Quantity>
      <GSTAmount>0.49</GSTAmount>
      <GSTRate>0.07</GSTRate>
  </Invoice_Line>
- <Invoice_Line>
      <Key>001</Key>
      <UnitPrice>8.00000</UnitPrice>
      <Quantity>1.0000</Quantity>
      <GSTAmount>0.56</GSTAmount>
      <GSTRate>0.07</GSTRate>  
</Invoice_Line>
- <Invoice_Header>
      <Key>000</Key>
     <BusinessUnit>HDB21</BusinessUnit>
     <InvoiceNo>6Y0575</InvoiceNo>
</Invoice_Header>
- <Invoice_Line>
    <Key>001</Key>
    <UnitPrice>49.50000</UnitPrice>
    <Quantity>1.0000</Quantity>
    <GSTAmount>3.47</GSTAmount>
    <GSTRate>0.07</GSTRate>
</Invoice_Line>
- <Trailer>
     <Key>TRL</Key>
     <TransactionID>RCTV</TransactionID>
     <TotalFeedLine>96</TotalFeedLine>
     <HashTotalValue>212.00</HashTotalValue>
</Trailer>
  </ns:MT_EINVOICE>
Mapping as follow:
                                               IDOC
<Control_Header>   ->    <Control_Header>
<Invoice_Header>   -->  <Header_Invoice>
<Invoice_Line>      --->        removeContext  -->  <Line_Invoice>       this is the child node of <Header_Invoice>
<Trailer>               -
>    <Trailer>
The result of the using the above Payload get the following result which not wht I seek
<Control_Header>
<Header_Invoice>
      <Line_Invoice>
      <Line_Invoice>
     <Line_Invoice>   *** This belong to the Invoice_Line of the second <Header_Invoice> at the payload
<Header_Invoice>
     <Line_Invoice>   *** THis segment is empty
<Trailer>
I required the Line_Invoice to belong to the child of the second <Header_Invoice>, I have tried using
removecontext with splitVaue and collaspeContext but to no avail.
May I know what is my mistake on the mapping of the Invoice_Line to Line_Invoice>

Hello,
There should be something that could correlate the Invoice_Header/Key and Invoice_Line/Key. In your example, both are the same for the first and data set. If the sample looks like the one below, it is possible to sort things by correlating the Invoice_Header key and Invoice_Line key
<Invoice_Header>
  <Key>000<Key>
</Invoice_Header>
<Invoice_Line>
  <Key>000<Key>
</Invoice_Line>
<Invoice_Line>
  <Key>000<Key>
</Invoice_Line>
<Invoice_Header>
  <Key>001<Key>
</Invoice_Header>
<Invoice_Line>
  <Key>001<Key>
</Invoice_Line>
An example mapping could look like this
For Header
Invoice_Header --> Header_Invoice
For Line
/InvoiceLine/Key --> removeContext --> splitByValue:valueChanged --> Invoice_Line
The subfields of the invoice line would also follow a similar logic, you just need to use formatByExample --> splitByValue:eachValue so that the context levels are the same.
Hope this helps,
