Random Collection Properties

Negative Amount Allowed

When this parameter is checked, negative amount is allowed on the tracking materials inside this tracker process unit. This means that the material does not automatically exit the tracker process unit when the amount reaches zero. This feature is typically used to handle integrating mass balance problems because of inaccuracies in the signals or inaccuracies in manual registrations.

Material outdate time

This parameter is used to determine how long tracking materials can stay inside this TPU before they are considered outdated, and should automatically be removed from the TPU. The time is specified in seconds since CreateTime. If the parameter is set to 0, no outdating is performed. For the outdate functionality to work, an output definition of type TM Outdated must be configured, and the corresponding control port must be set to true.

Maximum Material Transfer

This parameter is used to control the maximum number of tracking materials to be moved in one time step. This functionality is used to prevent overloading of the system when transactions involving large numbers of materials occur.
