Transfer customer specific Roles assigned to a customer from R/3 to CRM

Question

Hello dear all,
on R/3 side there are customer specific roles defined and assigned to customers. These roles are sales area depending.
On CRM side we plant to uses the Employee Responsible relationship to build up these customer specific roles. To differentiate these roles we want to use the partner function which is assigned to the sales area.
Can anybody show me how to do the initial load of the CRM system and map the role to the Employee Responsible relationship?
I assume that I have to create a own mapping function module to realize this. Where do  I register this function module so it will be used during the initial load? How do I debug these functionality?
A similar functionality we have to build up in case of the upload to the R/3 system. There we have map the Employee Responsible relationship to the specific role and assign it to the customer. Where do I register this function module?
Thanks for your help!
Best regards
Michael

hi
In order to replicate the ECC customer to CRM customer the following steps (tips) might be helpful to you:
First a Mapping structure should exist between business partners in SAP CRM and ERP ECC Customers in both the directions. In the ERP ECC system you can see this mapping using transaction /nPIDE
You should create your own account group for the data transfer from SAP CRM to ERP ECC
In SAP CRM, the roles sold-to party, ship-to party, bill-to party and payer are assigned to the classification Customer and the customer is assigned to exactly one account group in ERP ECC
For consistent distribution of Business Partners with identical numbers in both the systems, the internal number range (ex. 1-5999) should correspond to an external number assignment in the ERP ECC system or vice versa. Thus a business partner is given the same number in both systems.
For data exchange to be successful, you must ensure that the field control (mandatory fields) between the CRM system and the ERP system matches.
Besides Both SAP CRM and SAP ECC can talk to each other only when there is some settings done in the middleware. And for the CRM only a small plugin is needed for the ERP/ECC Connectivity.
Now whenever you have both the system mapped then if you create a BP in CRM it will automatically flow in the ERP System. And also the vice versa. As for the roles are concerned, the roles like ship-to-party and some few specific roles are mapped in ECC system. For a complete look at roles matching have a look at the following link.
http://help.sap.com/saphelp_crm50/helpdata/en/52/cff837a9aae651e10000009b38f8cf/frameset.htm
Once you have created a BP in CRM it will be created in some Account group in ECC. And in that AC GRP you will be not be able to create the Customer with identical ID. So if your systems are connected then even manually you also cannot create same BPs.
And for all of these the PIDE settings in ECC needs to be maintained properly.
Hope it serves your purpose
