# Inventory Transaction Entry (IT.E)
Read Time: 1 minute(s)
The IT.E procedure is used to enter individual inventory transactions which record the movement of materials from one location to another. The operator enters the part number and quantity being moved, the location it is moving from and the location it is moving to.
When the operator's entry is filed the system creates a record in the Inventory Transaction file (IT) which records the pertinent information about the transaction. At the same time it updates the inventory balance in the Inventory file (INV) for both the "from" and "to" locations. To record the financial effect of the transaction, inventory register (INVREG) records are created when the record is filed.
If the balance on hand in the" from" location will go negative as a result of processing the transaction a message will appear to warn the operator of this situation. If the "Negatives OK" flag in the associated INVLOC file is set to "N" then the system will not allow the transaction to be processed.
