BalancedTtsStatement.xq does not allow conditional abort

[ibruynin]

Is the following code pattern allowed?

{
ttsbegin;

if (condition) 
{
   ttsAbort;
   return;
}

ttsCommit;
}

Now the BalancedTtsStatement.xq rule complains about it.

and for the record... this does work:

{
ttsbegin;

if (condition) 
{
   ttsbegin;
   ttsAbort;
   return;
}

ttsCommit;
}

and that's not the intended fix, right? ;)

[dickwenning]

also below structure is not allowed

try
{
ttsbegin
….
ttscommit
}
catch
{
}

What if you put a ttsabort in catch statement?

[dickwenning]

hi ha365
as far Im aware aan error in a TTS will rollback to tts level 0, from that point the catch is used,
so no need for ttsabort

Hi, @dickwenning is right here. As mentioned in the X++ standards, you should not use ttsAbort directly to cancel the current transaction. Always use throw to do that. The standards apply to AX 2012, but they should still be valid in D365FinOps.
