As far as I see, the answer is NO.
But when the transaction was physically startet and after endet,
then status can be tsInactive.
See the nice example in IBO4\Tutorials\TransactionOAT to verify this.

Yes, when IBO needs to query metadata to reflect dataset details for
display reason. If you set the SchemaCache to an valid directory, this
happens only once. Without having SchemaCache set, this happens always
after opening the dataset - when any controls assigned.

IMHO you should.


Hope that helps,
