Writing an Upload Program for Business Partner, its address and Attributes

Question

Hi SAP Gurus,
I am in process of writing a tech design and code for an upload program which requires uploading a list of million Business Partners, its address (primarily Zip Code) and a list of Marketing Attributes of those Business Partners. The data will come in a .csv extract which will contain the BP Name, Zip Code, Marketing Attributes (X, Y, Z, etc) and then through this upload we will be creating BPs in the system and then updating its address and then Marketing Attributes.
The approach that I have chosen is -
1) Select the file from the presentation server using the class/method CL_GUI_FRONTEND_SERVICES /GUI_UPLOAD FM
2) Call the FM TEXT_CONVERT_XLS_TO_SAP to transfer the content of the MS Excel file to an internal table for further processing.
3) Call the FM - BAPI_BUPA_CREATE_FROM_DATA and pass the necessary parameters to upload/create the Business Partner and then call the FM BAPI_TRANSACTION_COMMIT to ensure the upload is complete.
4) Once the upload of BP is complete, then upload the address (Zip Code) data through the FM - BAPI_BUPA_ADDRESS_ADD and then call the FM BAPI_TRANSACTION_COMMIT to ensure the address upload is complete.
5) Post the upload of BP and address data, call the FM CRM_MKTBP_PROCESS_BP_LIST to upload the Marketing Attributes of the Business Partners to the relevant tables and then again call the BAPI_TRANSACTION_COMMIT.
I just wanted to check if the above steps are correct or am I missing something important there??
Would appreciate expert opinion/guidance on this.
There is a time constraint on completing this; hence would appreciate a quick and reliable response to it.

Hi Clemens,
Thanks for your input.
So, just wanted to re-iterate the points you highlighted -
1) Instead of presentation server, you want the file to be read from application server and schedule this program as a background job? Am I following you correctly?
2) Link the address upload along with the BP upload only (at the same time instead of separately) to ease of double processing through one FM - BAPI_BUPA_CREATE_FROM_DATA
3) Calling BAPI_TRANSACTION_COMMIT every 1000 BPs or so for faster processing.
However, you did not mention anything about attribute upload. Is that approach fine? or do I need to include anything more there?
Please confirm and then I can close this question.
BR,
Ravi
