 1. If there are more running instances for the same Module only the first one is allowed to continue, the other active Instances must be aborted. This means that the current in-progress Module Instance for which the check is done needs to query if it itself is in the earliest (MIN) of the set of active Instances for the Module. If this is true, the Instance can continue. Otherwise it will be flagged to be aborted (Internal Processing Status Code `Abort`).This  will trigger an update of the `MODULE_INSTANCE` table to set the Execution Status Code to `Aborted` for the current Instance and avoid executing of the regular Module logic
