Is There ANY Flexibility in BS Acct Assignment for Sales/Purchase Invoices?

Question

We are about to go live; and, we have a Chart of Accts that not only breaks out our Income Statement accounts by division, but also does so for our Balance Sheet accounts.  Even so, apparently B1 does not have the flexibility to modify the balance sheet acccounts used for tracking Accounts Receivables and Accounts Payables at the marketing document level.  Since Business Partners may be purchasing (in the case of Customers) or selling (in the case of vendors) from any of our three divisions, we cannot setup a single AR or AP account in the BP record.  So, how do we best modify the B1 setup to have a manageable level of work to separate these transactions out into the multiple accounts?  Our ultimate goal is to be able to create three different BS, IS and SCF reports for each division.  However, the complexities of this larger task will be addressed later.  We have the SDK and are willing to make system modifications using this tool if we can achieve our desired result.
Thank you for any and all assistance!

I suppose I should also ask how cash and cash-equivalent BS accounts could be split out when receiving payment...

Answer 1

Felipe, I GREATLY appreciate your response.  Your comments regarding means to simplify my creation of trials balances is appreciated.  However, I will not have the opportunity to put this to good use if I am not able to separate out the original data entry.
I still do not see how to modify the default AR or AP account on a document.  Recall, any of my customers may be purchasing from any of the company's three divisions; and, any of my vendors may be selling to any of the three divisions.  Further, we do not want to maintain separate BP records for each customer, since this will require undue maintenance and/or problems with reporting.  I simply wish to have control of the AR and AP accounts used in the journal entry associated with an AR Invoice and AP Invoice.  I want to use division-specific balance sheet accounts instead of the one noted in the BP record.
If I can obtain an answer for this, this I would also be interested in how to perform the same split for the several other balance sheet accounts, including (but not limited to) the Goods Clearing account, Inventory Returns account, Cash at Bank account, AR Adjustments account, et al.
Thank you again!  If SDK changes are needed, this would be fine; but, any example of how to perform the code changes would be very much appreciated.  This would be my first jounral entry modification with the SDK.
Kind Regards,
