In Order to process the same actions on multiple object found you add the following to the action. IN BATCHES OF 1
Modify your process to something like:
-FIND ALL Customer IN BATCHES OF 1
-CREATE CustomerAlert WITH CustomerAlert.Customer=Customer, CustomerAlert.Importance='Normal', CustomerAlert.Subject='Daily Report Approval',CustomerAlert.AlertOn=CURRENT_DATE, CustomerAlert.Description='The Report should be reviewed each morning and approved prior to 9:00 am.'
-CREATE AlertList WITH AlertList.Alert=CustomerAlert, AlertList.Subject='Report Approved', AlertList.Details='After reviewing the Daily Report, put a check in the completed box to acknowledge that you have reviewed the report. The system will automatically log the time and the user who approved this item', AlertList.Type='Confirmation'
Once executed the process will loop / repeat the actions until all the found objects are done. (For eg. if you have 10 customers) The log will display something along the lines of:
Executing Action FIND ALL Customer IN BATCHES OF 1
-Found 10 records
-Processing 1st Record
-Executing Action CREATE CustomerAlert WITH ....
-Executing Action CREATE AlertList WITH ...
-Processing Next 1 object
-Executing Action CREATE CustomerAlert WITH ...
-Executing Action CREATE AlertList WITH...
Hope that answers your question.
