Hi Marcus! Thx for your elaborate explanation. I have tested this and in my test with only a couple of purchase invoices I had no problems fetching very recently created invoices. I suspect when creating multiple transactions simultaneously, the system needs time to process and can only store the values once creation is successful. This is hard to prevent, because in case of an error or disruption of the service, a rollback must be performed. I have seen similar integrations that solved this using the MAX value of lastModifiedDateTime of the previous request result to perform the next request. Could this also apply for your process?
