| MRP Type | Defines how a material will be planned. GCSS-Army uses the following:
|
| Notification | A notification is the alert process that informs an end user that some type of action is required for Army equipment. |

| Standard Unit of Measure | Specifies which unit of measure is used for calculations in the MRP list and the stock/requirements list. |
| Stock | Non-expendable items of equipment identified in GCSS-Army as Material Planning Objects (MPO). An MPO number is created for each piece of equipment. |
| Stock Transport Order (STO) | Used to transfer stock from plant to plant or storage location to storage location. Stock Transport Orders are used for bin-to-bin movements within the same storage location. |
| Storage Location | Physical location where inventory is stored or virtual location where inventory is planned. |

| Vendor Master | This data set contains critical information for approved vendors relating to accounts and locations, and unique information relating to products and services approved for purchase. In GCSS-Army, the vendor master consists of data from the Defense Logistics Information Service’s Central Contractor Registry and the DOD Routing Identifier Code. |
