Delta Download from ISU BP to CRM BP doesn't work

Question

Hi Experts,
We are currently new implementing a CRM7.0 system which is connected to an existing ISU system. We now have an issue about the BP delta download from ISU -> CRM.
Replication Scenario:
ISU BP -> CRM BP, NOT SD Customer -> CRM BP. As ISU is the leading system to create BPs and in ISU a MKK BP will be created first then a SD customer will be generated based on a template. So the change of a BP is via BP transaction for MKK role, not via XD02 SD Customer.
Issue:
The middleware setting is done and initial download from ISU BP -> CRM BP is done and successful. However when I trying to change a BP (change a MKK BP via BP transaction) in ISU, the change is not replicated to CRM (no queues, no BDOCs). It seems the delta download is not triggered at all.
However, I have maintained all the settings based on the ISU Specifics on the Set-Up-and-Load Guide for BP. So the followings are maintained:
- ISU: COM_BUPA_CALL_FU maintained based on the Guide
- CRM: CRMC_BUT_CALL_FU maintained based on the note 757955
- CRM: V_SMOFEVOB maintained based on the Guide
- ISU: BTE table (T-code: BF31) maintained based on the Guide
After setting above, the initial load is working (necessary table like CRMCONSUM,  CRMRFCPAR etc. are maintained otherwise the initial download won't successful). However, the delta download from ISU BP (MKK) to CRM BP doesn't work.
The only uncertain thing for me is the setting for ISU : CRMC_BUT_CALL_FU. In the Guide only one sentence saying CRMC_BUT_CALL_FU needs to be maintained both in CRM and ISU and details refer to note 757955. However, the note 757955 only talks about FMs for CRM not for ISU/ECC. So in ISU/ECC the table CRMC_BUT_CALL_FU I activated for the following entries:
BPOUT BUPA  0100000 COM_BUPA_MWX_CREATE_MAIN

Not sure if the above setting is correct or not (some of the setting may not necessary, is that will impact the delta download from ISU to CRM)
Also what's the purpose of maintain two tables in ISU/ECC (COM_BUPA_CALL_FU and CRMC_BUT_CALL_FU)?
Also I have read some notes that the ISU BP -> CRM BP delta download is not triggered by above tables, it is triggered by BADI PARTNET_UPDATE, is this true, a bit confused.
I am looking forward a solution from you experts.
Thanks,
Laurence
