tMDMCommit explicitly commits all changes to the database made within the scope of a transaction in MDM.


This component is used to control the point in an MDM Job at which any changes made to the database within the scope of an MDM transaction are committed, for example to prevent partial commits if an error occurs.

Note that if you need to commit each statement as an individual transaction, you have to use the Auto Commit function available in the connection component.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.
