Z table middleware replication from R/3 to CRM

Question

Looking for a CRM Middleware Guru out there !!!
I'm trying to replicate a simple R/3 table (list of countries in my example below. The replication must include both initial and delta downloads.
My problem is the following:
When doing an initial load using Transaction R3AS the BDOC is created correctly.  
The traffic lights are green in transaction SMW01 with a status of Confirmed (fully processed). 
The segments of the BDOC are populated with the correct value from R3 <b>BUT</b> <b>the table on CRM is not populated.</b>
Here is what I have done so far:
1-Created table on R3 ZCOUNTRY
2-Created mapping Function on R3 Z_CRS_MAP_ZCOUNTRY_BAPIMCTS
3-Created extract Function on R3 ZCOUNTRY_EXTRACT
4-Created an entry in Table CRMSUBTAB for Function ZCOUNTRY_EXTRACT
5-Created Receiving Module in R3 Z_CRM_COUNTRY_COLLECT_DATA triggered on SM30 for the Delta Load
6-Created table on CRM ZCOUNTRY
7-Created Bdoc on CRM ZCOUNTR_MESG
8-Created validation Function on CRM ZCRM_ZCOUNTR_MESG_VAL
9-Add an entry in SMW3BDOCIF for BDOC ZCOUNTR_MESG and Validation Function ZCRM_ZCOUNTR_MESG_VAL
10-Created mapping Function on CRM ZMAP_COUNTRY_BAPIMTCS_TO_MBDOC
11-Created MW Adapter Object in CRM ZCRMCOUNTRY
12-Created a replication Object on CRM ZCOUNTR_MESG
13-Created a publication on CRM ZCOUNTRY
I'm not sure why the CRM does not get populated. Could it have anything to do with "GUID" keys?
The 2 fields on my bespoke table are:
-Country
-Continent
In my Root Data Structure for the MBDOC do I need to add GUID as the first fields i.o.w.
-GUID
-Country
-Continent
When I choose my segment fields do I choose (?):
-GUID
-Country
-Continent
In my CRM Mapping function how do I populate the GUID field? (see the code below in the mapping function).  How do I get a value into lv_sfakey and does this have anything to do with the GUID mentioned above.
MOVE lv_sfakey TO segment_line-guid.
AND
MOVE lv_sfakey TO ext_line-data-guid.
Thanks for any help

Hi Manoj,
I have a similar situation as you have described. However my problem is that when i start the initial load, the status in the RFC inbound queue of CRM (smq2) shows stop and the oject shows the status running. I dont know how to debug the
Validation FM and Mapping FM written for the same. Can you please explain me the meaning of the status shown in the crm queue.
Thanks,
