Change based Alerts stop working periodically.

(0) ShareShare
ReportReport
Posted on by Community Member Microsoft Employee

Change based alerts were setup correctly and previously working.  Then some of the Change based alerts "Subjects" stopped getting generated while others continued to be generated and delivered via email.  It was discovered that if you toggled the "Enabled" check mark under | Organization administration | Setup | Alerts | Alert rules | for the specific Subject Alert rule that was not working, it would start generating alerts again, and produce the emails that you would expect in the "E-mail sending status" in System administration. 

Question:  How can I identify when these alerts stop working and also how can I troubleshoot as to why they have stopped generating?

    I just mentioned that as a side issue I had..  The problem is still the Change Based Alerts not even being generated for specific Alert rules.  Until I had toggled the "Enabled" check box, then they started generating again. Even before the e-mail distributor is involved.

    Does that suggest that the problem is not necessarily with alerts but perhaps with the e-mail distributor?

    Thanks Brandon, Looking at the EventCUD table all the BatchId's are 0's so everything looks good there.  I think at this point I will have to wait till it flakes out again and then go back through these points.  I have notices however in this troubleshooting that I have had a few "Failed" E-mail sending status records that I had to Restart send on before they would deliver. All good after that.

    Check the EventCUD table to see if you have any stale records, typically identified with by the Created date/time.  If those records have BatchId that is not a null GUID (all 0's), then something went wrong in the batch and they were orphaned afterward.  I believe you can reset the BatchId back to all 0's and they should process on the next pass.  If you have stale records that do not have a BatchId, that suggests something else is wrong.

    The database log utility will run a cleanup routine when changes are made. This can affect the alerts notifications. On further review, it may only be necessary to open the database log Setup and exit to trigger SysFlushDatabaseLogSetup::main();

    The alerts batch is completing normally and in a reasonable amount of time.  We are a fairly new AX environment, only 30 alert rules and 150 total users.  We do not have any disabled users with active alerts.  What do yo mean RE: your Adding/editing Db log sentence?

    Check to see that the alerts batch is completing normally, and that it executes in a reasonable amount of time. If the process does not complete, those CUD events are still outstanding for later.

    Check to see that alerts are not on tables like ReqTrans that have potentially huge numbers of daily records. I've seen where having the alert disabled does not prevent that table from being included in the CUD processing.

    Adding /editing the database log should run a clean-up process - sorry - I forget the name of the method.

    Check that there are no disabled users with active alerts. Either disable or delete their alerts.
