Hi Nabendu,
I can only think of one thing, instead of using 170 routing rules, why not just join the xpaths using EX
e.g /Root[companyCode='1111' or companyCode='1122'] EX for interface 1
and /Root[companyCode='2222' or companyCode='2211'] EX for interface 2
that way you only have two conditions.
Customise your 'XPATH' Expressions in Receiver Determination

Mark
