Alerts are not getting generated for new scenarios

Hello All SAP PI Experts,

We had configured alert setup using SolMan for PI 7.4 single stack two months ago. We had created alert rule objects in ID and included all the scenarios that were existing then. The alerts would get generated for all the errors.

Later, some more scenarios were created and these ICOs were added under alert rule objects. But now, the errors are not getting reported for the new ICOs although it is working fine for old ICOs.

Kindly suggest what actions need to be taken for this.

Thanks in advance.
