I believe you are correct accounts are immutable in formal accounting. In
formal accounting transactions are immutable as well. Yet we allow users to
change transactions if they choose not to adhere to formal accounting rules.
In that sense I believe we can also allow users to do the same with accounts
if they choose to do so, at least within reasonable limits.
These limits are:
- the commodity shouldn't be changed. It wouldn't make sense that an account
that was tracking USD suddenly starts tracking EUR. The values wouldn't match
- GnuCash makes certain assumptions about Accounts Receivable and Accounts
Payable account types and stores more information in those internally than in
other account types. Changing types on these accounts would violate these
assumptions and/or would lose the added information. To avoid these changing
account types to/from A/R and A/P should not be allowed.
- John also mentions the Trading account type. While it's an internal use type
as well I don't know much about the assumptions gnucash makes on these account
types nor whether changing an account to/from such a type would affect
gnucash' proper functioning or not. Nor can I imagine a use case where it
would make sense to change to/from a trading account. They are generated
automatically when needed.
