Delete or invalidate tag value in Osisoft PI via TagFixedQuery

Dear all,

I would like to ask you for help with following problem:

I store with PCO Query in mode TagFixedQuery value with Timestamp in Osisoft PI:

STORE "TagName"="value" AT "Timestamp";

Afterwards I need sometimes to delete or invalidate stored value.

Can anyone help me how to do it?

Thanks in advance

    From there select your version and then look for Stale And Bad Points. Decomission is what I think you need to do, but read the help documentation to figure out how to achieve the result that you seek.

    Cheers, Mike
