To specify whether items with a particular status can be allocated:

1. From the Module Menu select Maintenance, Circulation and then Item Status.
2. Select the status you want from the list.
3. Set Block allocation to Yes or No.
4. Click Save or Save & Close.

For example, if you try to return a reserved item that has a status with Block allocation set to Yes you’ll be prompted with an ITMSTATUSBLKRSV alert. You can override the alert and allocate the item if you have a high enough privilege level.

Null means the same as No.
