Thanks Helen and Paul for the information on IBO's DML caching. I had not explored this before. Now I know more about it. I have used FB events.

My task is not first synchonisation between data sets. It is gathering data from a 3rd party app and starting a longish task processing the data in the FB server. Using a separate thread is one way. Queuing the process is another. At present I am looking at options.

Thanks again,
Russell
