Bill,
I guess I am saying it, but don't shoot the messenger. Here is an overview of KB 933642:
The account cannot have a balance.
Fix: Transactions > Financial Clearing
The account cannot have any current activity or any year-to-date transactions.
Fix: Routines > Financial > Year End Close
The account cannot have any historical data, such as a transaction history or any transactions that occur in years that are closed.
Fix: Utilities > Financial > Remove History; this will create an out-of-balance situation
The account cannot have any multicurrency data in the MC00201 table or in the MC30001 table.
Fix: Routines > Financial > Year End Close & Utilities > Financial > Remove History; Delete MC00201 where ACTINDX = 'Index_of_Acct_to_Delete' & Delete MC0030001 where ACTINDX = 'Index_of_Acct_to_Delete'
The account cannot be contained in a quick journal or be in a saved batch.
Fix: Tools > Setup > Financial > Quick Journal & Tools > Routines > Master Posting > Post Batches
The account may not be included in an allocation account either as a breakdown account or as a distribution account.
Fix: Cards > Financial > Fixed Allocation and Variable Allocation
Note: You can delete variable allocation accounts and fixed allocation accounts at any time because these accounts do not hold a balance. However, if any transactions contain a balance, those transactions will have a blank distribution account. If you add the allocation accounts again, the accounts do not reestablish the link between the transactions that contain a balance. The link is not reestablished because the accounts are given a new account index value.
The note above is very instructive... The implication, backed up by the post above is any accounts with references/balances in areas not validated prior to the accounts' removal will result in blank distribution accounts, which the links cannot be easily reestablished for, because re-created accounts will not have the same index numbers.
