            Bug ID: 455470
           Summary: Some split transactions in an account in a foreign
                    currency cannot be edited or deleted
           Product: kmymoney
           Version: 5.1.2
          Platform: Microsoft Windows
                OS: Microsoft Windows
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: file

  Target Milestone: ---

I have been using KMM for a couple of years. My KMM data file has several
foreign currency accounts as well as accounts in my base or default currency.
Transactions from before 2020 were imported from Quicken. This week I began
editing transactions where the foreign currency conversion rate was set at 1:1
which causes errors in reports (see report for bug 455171). I have successfully
updated the conversion rates for all transactions in a current account for over
two years from 1999, but now I have found transactions that I cannot edit.
These are split transactions, each split into eight component sub-transactions.
They occur every month, so I have already processed about 26 of these split
transactions with earlier dates, but all the ones following that I have tried
cannot be edited. Other transactions in this account, including other split
transactions, can still be edited, both from earlier and later dates. I
wondered if deleting the transaction that cannot be edited and replacing it
with an equivalent transaction would help, but the transactions that cannot be
edited cannot be deleted either.


STEPS TO REPRODUCE
1. Open the KMM data file and the foreign currency current account which has
several years of imported transactions with currency conversion rates to be
updated
2. Start with the first month. (Dealing with one month at a time keeps things
manageable.) Open each split transaction in turn to edit the splits. (Update
each memo field in turn with something trivial and save, which brings up the
exchange rate editor. Update the exchange rate and save. Continue for all
relevant split elements. Save the split transaction.)
3. When the split transactions for the month have been done, select all
remaining transactions for the same month that are not split and are not
transfers between accounts in the same currency. Click 'edit' and 'save'. This
brings up the exchange rate editor for all the selected transactions in turn.
Update the exchange rates and save.
4. Go on to the next month if one is available.

OBSERVED RESULT

After processing 26 months of transactions I found a split transaction that
cannot be edited or deleted. It can be opened and the splits can  be displayed
but nothing can be edited. With the transaction highlighted I can right-click
to see the pop-up menu. There are 15 menu items but only the first three and
the 8th to 12th items are available, the rest are greyed out. The first three
includes  'edit' and 'edit splits' but neither works because nothing can be
edited and the only option available after selecting either is to cancel or
discard. I have closed KMM and opened it again. The problem remains. There does
not appear to be anything wrong with the file. The 'Consistency Check' tool
finds nothing wrong. I have found the same problem with all subsequent
instances of this transaction I have tried. (It may be irrelevant, but note
these transactions have more split elements than other split transactions in
this account, so maybe KMM has some limit on what it can handle.)

EXPECTED RESULT

Edit the transactions and update exchange rates in the same way I edited the
same transactions from earlier months.
