Oracle Project Manufacturing reserves segment19 and segment20 of the Stock Locator key flexfield to store the project and task numbers. You should not attempt to modify these two segments.
If you are installing Oracle Project Manufacturing for the first time, the system automatically enables segment19 and segment20 of the Stock Locator key flexfield when you create the first inventory organization and check the Enable Project References check box. You can then enable additional segments to reflect your physical stock location layout.
If you are installing Oracle Project Manufacturing in an existing Oracle Applications installation and currently use segment19 and segment20 of the Stock Locator key flexfield, change the current flexfield schema and use other segments. The system does not support automatic conversion.
A project locator is a locator with a project or project and task reference. It is also a logical partition of a physical location. Project locators are used to track project hard pegged material. Project inventory needs to be stocked in a project locator and needs to be transacted in and out of a project locator. Since locators can be dynamically created, it is not necessary to predefine project locators.
A common locator is a locator without a project or project and task reference. It is also a real, physical location. Common locators are used to track common (soft pegged) material.
Note: Although a project locator is a logical partition, the system still regards it as a physical locator for physical and cycle counting.
Project locators differ from common locators by the existence of values in the project and task segments in the flexfield definition of the Locator. If the structure of the physical location is Row/Rack/Bin, the structure of the Locator flexfield would be Row/Rack/Bin/Project/Task. For example, the concatenated value for a common item in Row 1, Rack 4, Bin 2 would be 1/4/2// while the concatenated value for a project item in Row 1, Rack 4, Bin 2, Project C4501, Task 2.1 would be 1/4/2/C4501/2.1.
Use project locators to track inventory by project. If an inventory item needs to be identified by project, you need to turn Locator Control on for the item.
Since locators can be created dynamically (Locator Control = Dynamic Entry Allowed at item level), you do not need to predefine all project locators. Oracle Project Manufacturing provides defaulting and validation logic in order to keep the use of project locators transparent.
