Issue
Symptoms
Unable to view the Asset tag field on a consumable asset form, even after modifying the form view to display the asset_tag field
Cause
There is an Out of the Box ACL "alm_asset.asset_tag" which is preventing the field "asset_tag" to be displayed.
There is a condition on the ACL, where the field would be displayed only when the class is "not" consumable.
Resolution
The condition can be modified if you would like the field to be displayed on all asset classes.
