The summary of my code like this : procedure saverecord; begin try transaction.savepointbegin; dataset1.append; ... ... dataset1.post; dataset2.append; ... ... dataset2.post; dataset1.applyupdates; >>>>>error from server dataset2.applyupdates; ... transaction.commitretaining; except transaction.savepointrollback; >>>>>caused by dataset1 and dataset2 state is set to dsbrowse, than I do dataset.edit dataset1.edit; end; end; The dataset1 and dataset2 buffer don't remove than I can fix error of data input, I call saverecord again. And I got other error from server because dataset1 execute SQL "UPDATE dataset1 ..WHERE key1=...." and not "INSERT INTO dataset1...", so dataset1 still empty (could not update cause server can not found key1 of dataset1. The second error come from dataset2.applyupdates caused by dataset2 have foreign key to dataset1. The conclusion : Is possible to make dataset1.state still in dsInsert after savepointrollback, because after savepointrollback dataset1.buffer still exists?
