# Restrictions on shelf-life dates

The following restrictions have been added to the shelf-life dates for batches and sub-batches:

- The **Manufacturing date** must be earlier than the **Shelf advice date**
- The **Manufacturing date** must be earlier than the **Best before date**
- The **Manufacturing date** must be earlier than the **Expiration date**
- The **Manufacturing date** must be earlier than the **Destroy by date**
- The **Best before date** must be earlier than or equal to the **Expiration date.**

The controls listed above are triggered whenever a user manually updates the batch/sub-batch dates (for example, by using the **Reset shelf life dates** feature) or dates are automatically updated by the system.

Users can specify if manual modifications to the shelf-life dates for a batch or sub-batch should be secured via electronic signature by enabling the **Signature required** parameter for the **Update shelf life dates for batches** and **Update shelf life dates for sub batches** requirements in the **Electronic signature requirements** form (**Organization administration > Setup > Electronic signature > Electronic signature requirements**).
