Days Until Expiration

Identifies the number of days before a Lot "expires". This is calculated using the 'Batch Expiration Date' on the Properties tab of the Production Batch Record View and subtracting the current date. This can be edited by changing the 'Batch Expiration Date' field on the Properties tab of the Production Batch record view. This is not stored in the database.

If the Batch Expiration Date is:

• Blank, then this will be blank.
• In the future, then this will be a positive value indicating how many days are left until the Batch is "expired". 
• In the past, then this will be a negative value indicating how many days have passed since the Batch "expired".
