I have a maintenance form that maintains Table A. I would like to log the before and after image of each changed column in Table A to Table B. I have placed the logic to do this into Table A’s HookPreSave method. The problem I am having is that I cannot find a way to get Table B to participate in Table A’s Transaction. If there is an error in the validation of Table A changes are not applied to Table A however these changes are being logged to Table B even though Table A has not passed the validation process. I would like to know how to get Table B to update only if Table A successfully updates. Also, if either table fails to successfully update then I want them both to rollback. They must remain in sync. AutoUseTransactions is set to true on Table A’s BO.
