Loading Chart of Accounts from SAP into Account dim in BPC automatically

Question

Hi,
for my client I would like to take a predefined flat file from SAP containing chart of account details (account id, description and parent) and load and  process them automatically using dtsx packages in BPC 7.0 MS.
Also, I want the package to able to be able to change details when it finds an already existing account id (e.g. if the description changes) and only for the properties contained in the flat file (i.e. keep the property values the same in BPC for those properties which are not in the extract for existing account records), or to add new accounts for those that don't exist.  I don't want the existing dimension completely replaced, as the SAP file won't contain info for fields like ACCTYPE, or TYPEELIM for example.
I find the help in Data Manager extremely confusing and am not sure which bits are current or have been superceeded.
I am an application consultant with limited knowledge of DTS/ SSIS and I wonder if someone can give me a step by step detail of  what I must do to achieve this. I am sure that many people would like to do something similar.
regards
Scott.

Here is what you need to do in the SSIS package.
1. You need to create exactly same structure as MBRAccount Table. Let's say tmpMBRAccount
2. Export Account data from SAP as FlatFile
3. You need a Script to fill in ACCTYPE or other properties that doesn't exist in SAP but mandatory for BPC account dimension. This script will change exported Flatfile.
4. Import step3 flatfile into tmpMBRAccount table.
    Some users import data into MBRtable directly but it is not good because if error happens,
    there is no way to roll back until restore table from backup database.
    If users use temporary table as we do, Admin task will backup and roll back if error happens.
5. Run Admintask and point tmpMBRAccount table as source table.
6. You need another script to update Excel member sheet from updated mbr table.
    If you don't have this script, data member will be inconsistent between excel member sheet and MBR table.
Some customer add more steps to validate members or error handling.
If you are not an expert of SSIS, I think you need a technical consultant for doing this.
There are an example package in BPC sample package folder but it is very basic one.
Thank you.
