Context Problem in Mapping

Hi All

this is my IDOC Structure (I have only posted the required structure)

<?xml version="1.0" encoding="UTF-8"?>

<ZCO_CCM>

<IDOC BEGIN="1">

<EDI_DC40 SEGMENT="1">

</EDI_DC40>

<Z1PARNT SEGMENT="1">

<LVROM>Z</LVROM>

<Z1CSKS SEGMENT="1">

Not coming<b><HIGHERDEP> </HIGHERDEP></b> <STDHIERARCHY>0001-1</STDHIERARCHY>

</Z1CSKS>

</Z1PARNT>

<Z1PARNT SEGMENT="1">

<LVROM>Z</LVROM>

<Z1CSKS SEGMENT="1">

<b><HIGHERDEP>0450</HIGHERDEP></b>

<STDHIERARCHY>0001-1</STDHIERARCHY>

</Z1CSKS>

</Z1PARNT>

</IDOC>

</ZCO_CCM>

I am genereating the flat file, the tagret field should be creted only when the value in the field <HIGHERDEP>0450</HIGHERDEP> is present.

I am checking IF> HIGHERDEP->EXIST(Function)---->THEN->MAP Z1PARNT to tagert Root node ( With Node and ALSO TRIED with UDF which supress the node) the context of the field HIGHERDEP is Z1PART (one structure above)

while testing this mapping,

2 Times Z1PARNT Repeated ( 1st novalue, 2nd with value,in field HIGHERDEP)

on target i should 1 rows (with value in field) which i am not getting any row,

if i change the context of field HIGHERDEP to IDOC, on target side it is creating the row for the the Node Z1PART in which field HIGHERDEP is not coming.

any clue on this?
