Backdate Item Distribution
If you enter an item distribution and then backdate a transaction prior to the distribution, this can cause problems with inventory costing. It can also result in a negative on-hand count for the item in a null location. This is true especially for lot-numbered or serial-numbered inventory.
Best Practice
If you have problems with inventory due to backdating an item distribution, you should inactivate the item record and then create a new one. For more information, see Creating Item Records.
