Hi, When we have to upload changes to a campaign using the 200909 API we upload both ad and keywords changes at the same time using two threads. Sometimes we get a DatabaseError.CONCURRENT_MODIFICATION back. So my question is what concurrent modifications are allowed? Do we have to deal with one campaign at a time or one account or something else?
Here are the SOAP request and response that caused the error: <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w 3.org/2001/XMLSchema-instance"><soapenv:Header><ns1:RequestHeader soapenv:actor="http://schemas.xmlsoap.org/soap/actor/next"; soapenv:mustUnderstand="0" xmlns:ns1="https://adwords.google.com/api/ adwords/cm/v200909"><ns1:applicationToken>TwAbF7xAay84 ntBUiLrIaw</ns1:applicationToken><ns1:authToken xmlns:ns1="https:// adwords.google.com/api/adwords/cm/v200909">******</ ns1:authToken><ns1:clientCustomerId>9940465121</ ns1:clientCustomerId><ns1:developerToken>p2yMk6iT8bAMXbyt3cCuOQ</ ns1:developerToke n><ns1:userAgent>AdWords API Java Client Library -
