OK folks, I think this one is solved. Here is what CA advised us: If a project is inactive or financial status is Closed before a timesheet is posted then PRRMEXPORTED is left at 0. This does not show as an invalid transaction because that screen only shows errors after posting (from IMP_TRANSACTIONIMPORT and PPA_TRANSCONTROL tables). Until the posting the financials don't exist here. So we find ourselves with posted time entries which have not been financially posted. We are going to search these out, open the projects and repost. We haven't helped things by having a large number of open time periods, where users can go back and adjust time on an inactive/financially closed project. There is an Enhancement in to stop projects being closed or deactivated if there are outstanding items but this is not currently scheduled for immediate release even in v13. So we are going to see if we can put something in place to check for these closed projects prior to posting, reopen them, post and then close them again. Obviously we are also going to address our numbers of open time periods too. Hope this is of use to any one who has the same problem. Owen
