I'm not able to duplicate this issue although comment you have every field in CP table as required, so you cannot update interchangeability until these are completed. I presume these options are unique to each CP, so two thoughtsOnce I fix them, they seem to stay, but I need them to stick the first time. Any idea why this happens and how I Can solve?
1. if you only have one record per CP then you might as well incorporate them into the CP table.
2. if you want to keep as a separate table but complete it before all the required fields in CP are completed, investigate what is called transaction processing - keywords to search on are 'begintrans' and 'committrans'
in the frm_interchangeability form properties, change the Navigation Buttons property to No - you may also want to set the recordselectors property to no to get rid of the vertical grey bar to the left.It may seem trivial, but I would like the interchangeability sub-form to look like the "drawings impacted" sub-form. By this, I mean, I don't want to see the botom row where it shows # of records or the search stuff. I will always have 3 per CP so don't want to use up the realistate on the form.
