Synchronous Import Sets Remain in 'Loading' StateIssue When importing data using the out-of-box REST Import Set API the data will be imported into a Mode=synchronous Import Set. This Import Set will remain in State=Loading until set to completed by a Scheduled Job.ReleaseAll current ServiceNow releasesCauseWhen using the Import Set API to import data in synchronous mode each row (a record) is transformed as soon as the record has been loaded, only once that transform is complete can the next record be sent via the API. This means there is no way for the instance to know when the imported load is complete, as at any time a client could use the Import Set API to import further records (which is different to importing from other sources like Excel spreadsheets or databases over JDBC, where there is a finite amount of records that could be in the spreadsheet or returned by the SQL query). The way the instance handles this is that it will open a new Import Set the first time a record is created using the Import Set API for a table. Any subsequent records incoming via the Import Set API for that same table will use that same Import Set. There is then an out-of-box Scheduled Job 'Synchronous Import Set Completer' (https://INSTANCENAME.service-now.com/nav_to.do?uri=sysauto_script.do?sys_id=a09576d5c0a8006f0049f301c59f36b0) that runs once per day (by default at 18:00) and sets all Import Sets in State=Loading to State=Completed.ResolutionIf Import Sets remain in state 'Loading' for more than 24 hours check that the out-of-box Scheduled Job 'Synchronous Import Set Completer' (https://INSTANCENAME.service-now.com/nav_to.do?uri=sysauto_script.do?sys_id=a09576d5c0a8006f0049f301c59f36b0) is not disabled.
