Module 9441 Conclude and close a transaction

Module 9441 concludes a transaction. The module tries to write all buffered

changes to the selected machine table. If the action is successful, the

transaction is closed and the transaction handle is invalidated. Otherwise, the

transaction remains open. In order to conclude the transaction despite this,

correct the modifications so that no constraints are violated. If the changes are

not successful, the buffered changes cannot be saved (conclusion with

Module 9451).

Constraints:

The module can only be executed within a submit job.

Possible errors:

The module was not called in a submit job

No transaction was opened for the given handle

At least one modification made violates a uniqueness constraint defined for

At least one modification made violates a foreign key constraint defined for
