Hello,

I have mbbi records which are using stream/asyn.
For some reason my records become invalid after some time.
SCAN is passive and triggered through FLNK of the associated mbbo record.


Is there a way to recover from an invalid record?

It depends on why it went INVALID


What turns it into invalid in the first place?

Several possible things. It surprises me that the record dump below shows the .STAT field as NO_ALARM. Usually the .STAT field gives an indication of why the record went into alarm ... someone is not following the rules.


Did you print this record immediately after it went into alarm?

Ned

(Well, I could do some testing to answer that latter question...)

Thank you in advance,
