Inventory availability safety factor

Sterling™ Order Management System Software enables you to define an inventory availability safety factor that indicates what percentage of current or future inventory should be excluded during order promising.

About this task

For example, you may consider that your Planned Purchase Order supply is less reliable than your In Transit supply for order promising. Therefore, you may want to exclude 60% of the Planned Purchase Order supply type when promising, as opposed to 10% of the In Transit supply type.

By default, fractional quantities are not truncated. That functionality can be turned off by modifying the yfs.install.displaydoublequantity property in the <INSTALL_DIR>/properties/customer_overrides.properties file.

The behavior is as follows:

If the property is set to Y, the fractional quantity is used after applying the percentage. This is the default behavior.
If the property is set to N, the fractional quantity is truncated to the nearest lower integer after applying the percentage. For example, if a purchase order is placed with a quantity of 10, and the inventory availability safety factor percentage of the PO_PLACED supply type is set to 25%, a quantity of 7 would be available to fulfill future demand, as opposed to 7.5.

To modify, enable, or disable the inventory availability safety factor:
