Alarm's Associated data "optional" not possible?

I have some alarms with associated data. The value of associated data depend from udt parameters.
assDataValue1,assDataValue2,assDataValue3.
Some parameters are blank or empty and a blank value of the associated data is stored in alarm event data journal table.

Can we avoid to store empty value ? If I put a Null value in the associated data, with something like

if({vue4}="",None,{vue4})

the associated value is still stored.

I think that the only solution is to remove them after with a SQL delete.

What are your event data settings on the alarm journal in question?

You can combine those with the choice to make associated data dynamic or static to manually configure whether it's logged.

If that's not granular enough, then yes, an after-the-fact manual prune would be the way to go.

Yes, I have to store "Dynamic Associated Data" for alarm query journal filter, so I will prune unusefull stored values.
