This example shows how to revert edits for a data object in a project object ProjObj.

DataObj = ProjObj.Data;
BeginEdit(DataObj);
AddVariable(DataObj, 'TQ = tq', 'lbft');
AddFilter(DataObj, 'TQ < 200');
DefineTestGroups(DataObj, {'RPM' 'AFR'}, [50 10], 'MyLogNo');
RollbackEdit(DataObj);

This example shows how to revert edits when IsEditable is false and IsBeingEdited is true. ProjObj is a mbcmodel.project object, d and d1 are mbcmodel.data objects.

D = ProjObj.Data;
D1 = ProjObj.Data;
BeginEdit(D1);
tp = ProjObj.Testplan;
Attach(tp, D);

This example shows how to revert edits when IsEditable for D1 is false because it is Attached to the test plan. To modify D1, use the test plan. However:

OK = D1.IsBeingEdited
Is true. Calling CommitEdit will fail.
