Master data update and navigational attrivute

Question

Hi.
There is master data which is having some 10 attributes.All of them marked as a Navigational Attribute.But all the attributes are coming from R/3 and only last attribute(X) is not coming from R/3.This X is maintained in flat file.My questions are
1.After uploading all the remaing attributes from R/3 can we update the X through Flat file by creating sperate Infopackage and un mapping remaing objects.
2.Here there is no Hierachy.All the attributes are marked as a navigational attributes.So, Is there any question of drilling down on a particualar Attribute like organizational Unit,or Station or plant.
When we said all as navigational attributes we can make all the drill down and drill across operations on all of them corrrect??
It is very Urgent.

hi Vasu,
say you have master data infoobject ziobjmst, you can try
- make ziobjmst 'as infoprovider', rsa1->infoprovider->insert characteristic as infoprovider
- create infosource with flexible update, e.g zisX put infoobject ziobjmst and X in transfer structure, assign with flat file datasource.
- create update rules for ziobjmst from rsa1->infoprovider, assign with infosource zisX, assign ziobjmst with ziobjmst and X with X, let other infoobjects as 'no update'.
- create infopackage and upload data.
another way as mentioned by Vikash with look up from table A (e.g infoobject is A), you can create start routine in transfer rules and put code
data : it_A like /bic/pA occurs 0 with header line.
p is attribute table
select * from /bic/pA into table it_A.
then create routine for X in transfer rules, code
result = ''.
read table it_A with key /bic/A = tran_structure-/bic/A binary search.
if sy-subrc = 0.
result = it_A-/bic/X.
endif.
hope this helps.
