SRM-SUS Scenerio Replicating company code and suppliers to SUS via XI

Question

We have configured SRM-SUS scenario.  We have SRM and SUS on the same system but different clients.  We have configured extended classic scenario.  We are on SRM 2007 with SP5
Issue:
When I execute transaction BBP_SP_COMP_INI I get no errors.  I check SXMB_MONI in my SUS client and it has processed correctly.  However it does not update table BBP_SUS_BPCMPMAP.  I check SLG1 in SRM and SUS and get messages that data replicated.
When I execute transaction BBP_SP_SUPP_INI to move the SRM suppliers to SUS I check SXMB_MONI and everything processed correctly.  However, when I check table VENMAP there are no entries.
I then create a PO and send to SUS.  I get the following error:
Error in an XI interface: No partner found for partner number VNDR_ACCT_ Program: SAPLBBP_BD_VALUE_MAPPING; Include: LBBP_BD_VALUE_MAPPINGF11; Line: 436
When we debug the proxy it is trying to validate our SRM company code (VNDR_ACCT) in table BBP_SUS_BPCMPMAP which is empty.
It appears that SUS is not allowing the creation of external partners.  Does SRM to SUS transfers utilize the BP number range table which distinguishes external and internal BPs which is used when replicating suppliers between ECC and SRM.
Has anyone ever encountered this issue before?
Please advise.
Thanks.

Hello Nikhil:
I think my issue is that the XI proxys' are not being updated in SUS.  It appears to me that it is similar to when you are executing BBPGETVD between ECC and SUS (MM-SUS) and the BP number range in SUS is not set to accept external BPs.
So, When I execute BBP_SP_SUPP_INI and send SRM suppliers to SUS how does it know the VG5XXXXXXX.  When I replicate BBPGETVD I tell the VG5XXXXXXXX.  I did configure the "Managing Business Partners" SUS configuration but we are not using supplier registration so I do not have URL for UM or Notification.  I did update the "Central Vendor Group" , "Default Purchase Org", and "Currency".  Does XI use this setting to know where to assign the vendors or is there another piece of configuration I missed?
What I did to create the entry in table BBP_SUS_BPCMPMAP is I executed transaction BBP_SUS_BP_ADM and entered in the "Company Code" field the BP from my SRM system assigned to my ECC backend company code .  In the log sys field I entered the log sys of my SRM cleint.  I then completed the other required fields.  In the end it created the following entry:
101    4CF3AE33A6036B71E10000000AF8EF08 ERACLNT100 0001       0000000018
Client 100 is SRM and 101 is SUS.
I am able to configure SUS for MM_SUS and replicate suppliers and company code from ECC to SUS.  However, this does not use XI.  For thois reason I think my issue is a missing piece of config to tell XI where to create external business partners?
When I check the payload of my SRM PO it does not show the company code but uses BP 18 which is the SRM BP for my backend company code.  When I check BBP_PD for this PO in SRM it has my company code as "BE CO_ CODE"
Do you have any more suggestions?
Please advise.
Thanks.
