Thank you very much. I meant that one job which is everything in process waits for being called with another. One process call other

Trigger LogInsert [ Event = INSERT, Foreach = row/object, Time = AFTER ]
{
S className = ..%ClassName(1)
S cls=##class(%Dictionary.CompiledClass).%OpenId(className)
F i = 1:1:cls.Properties.Count() {
S prop = cls.Properties.GetAt(i)
S propName = prop.Name
i prop.Name'["%" {
b
S idRow = {Id}
x "s value={"_propName_"}"
s date=+$h,time=$p($h,",",2)
&sql(INSERT INTO LogClass (className, dateOfChange, fieldName, ip, newValue, oldValue, operation, timeOfChange, users)
            VALUES (:classname,:date,:propName, '192:168:1:1',:value,'','Insert',:time,'asfasf'))
}
}

Dear Sean I would glad to get a code for update trigger that iterate on all updated properties of a derived class and writes log to a log table.

Thank you very much for your help

Could you share documents where I'm able to read how to do it, please
