Mapping problem on different levels. (IDOC) to SQL

Question

I am having a mapping issue with a multi segment IDOC. It seems that it should be pretty straight forward but I am struggling. I have looked at some pretty good documentation but it still doesn't seem to help. The IDOC segments deal with text lines in SAP. The text identifier is at a higher level and the text lines are a level below the text identifier. I am writing these records to a SQL database table and the table will just contain the text identifier and then the text line. Both of these are at the same level. I need to combine the text identifier from the higher level to to each text line in the database table.
Here is my source file. It contains two different types of text identifiers (TDID)
<E1TXTH8 SEGMENT="1">
<TDID>0012</TDID>
<TDSPRAS>E</TDSPRAS>
<E1TXTP8 SEGMENT="1">
<TDLINE>This is line 1 of TDID 0012</TDLINE>
</E1TXTP8>
<E1TXTP8 SEGMENT="1">
<TDLINE>This is line 2 of TDID 0012</TDLINE>
</E1TXTP8>
<E1TXTP8 SEGMENT="1">
<TDLINE>This is line 3 of TDID 0012</TDLINE>
</E1TXTP8>
</E1TXTH8>
<E1TXTH8 SEGMENT="1">
<TDID>Z110</TDID>
<TDSPRAS>E</TDSPRAS>
<E1TXTP8 SEGMENT="1">
<TDLINE>This is line 1 of TDID Z110</TDLINE>
</E1TXTP8>
<E1TXTP8 SEGMENT="1">
<TDLINE>This is line 2 of TDID Z110.</TDLINE>
</E1TXTP8>
</E1TXTH8>
I wand this to map so that I see the following results:
<InsertStatement_ShippingText>
<MDB_tblshippingtext action="INSERT">
<access>
<TDID>0012</TDID>
<TDLINE>This is line 1 of TDID 0012</TDLINE>
</access>
<access>
<TDID>0012</TDID>
<TDLINE>This is line 2 of TDID 0012</TDLINE>
</access>
<access>
<TDID>0012</TDID> 
<TDLINE>This is line 3 of TDID 0012</TDLINE>
</access>
<access>
<TDID>Z110</TDID> 
<TDLINE>This is line 1 of TDID Z110</TDLINE>
</access>
<access>
<TDID>Z110</TDID> 
<TDLINE>This is line 2 of TDID Z110</TDLINE>
</access>
</MDB_tblshippingtext>
</InsertStatement_ShippingText>
So far I have been unsuccessful. I am mapping the access element to the lower level segment E1TXTP8. This gives me all of the text lines but the TDID is not filled in properly.
If I map the access element to the highler level E1TXTH8 then I do not get all of my text lines from the lower level. I have looked at the document "Replication of Nodes using the graphical tool mapper" but I still don't seem to understand my problem.
Any help is appreciated.
Thanks,
Jim

Hi Jim,
there are a couple of things to look at:
1. If you always have at least one E1TXTP8 segment under each E1TXTH8 segment, you can use the function useOneAsMany. Jin Chin gave you all the pointers to look at (remember to check the context for the mapping of your element "access")
2. If you test with samples that have a E1TXTH8 segment without a segment E1TXTP8 underneath, the function useOneAsMany will give you the error you encounter. In that case you need to use one of the different mappings described in the <a href="/people/claus.wallacher/blog/2006/04/17/replication-of-nodes-using-the-graphical-mapping-tool">weblog</a> you mentioned.
3. If it still doesn't work, can you give us the sample XML that causes the error?
