I tried to use this and it did not reduce the system-managed auto suppression list DE. I did not get an error. It just simply did not work. Any suggestions please and thank you in advance

Odd, happy to help you investigate further as it works for me, however there are now a couple of easier ways to do this declaratively. You can either use Query Studio to create your query then you can select an auto-suppression list as the Target DE when you save the query in the UI, or you can use the new Data Copy or Import Activity in Automation Studio which now enables you to select auto-suppression list as the source.

Oh wow, I didn't realize i could do that through Query Studio. Nice thank you. I would still like to know what I did wrong in the script, if possible please. below is the tweak I made:

var prox = new Script.Util.WSProxy();

var queryStr = '';
queryStr += 'SELECT DISTINCT';
queryStr += '\n EmailAddress AS [Email Address],';
queryStr += '\n hed__Do_Not_Contact__c,';
queryStr += '\n ID';
queryStr += '\nFROM Contact_Salesforce';
queryStr += '\nWHERE hed__Do_Not_Contact__c = 'True'';

var queryDef = {
CustomerKey: '79C0A4FD-E7B6-44C5-8301-AF60273377CB',
ObjectID: '79c0a4fd-e7b6-44c5-8301-af60273377cb',
QueryText: queryStr,
TargetType: 'DE',
TargetUpdateType: 'Update',
DataExtensionTarget: {
CustomerKey: 'A98B89C3-701E-4A81-9A5E-2174C9B5C8B8',
Name: 'Auto-Suppression List'
}
};
var updateQuery = prox.updateItem('QueryDefinition', queryDef);

Write('result: ' + Stringify(updateQuery))

</script>`

The issue is the line queryStr += '\nWHERE hed__Do_Not_Contact__c = 'True''; which ends with two quotation marks — you did not escape the quotation marks around the value. However, as this is a Boolean value, you should use queryStr += '\nWHERE hed__Do_Not_Contact__c = 1';

Wanted to follow up. Once I correct the error you identified, this fixed it. Thank you
