I have a layout with a personnel portal and associated portal for time sheet entry filtered by date set in a global field. I have added a delete button to the portal rows of the time sheet. When executed on one portal row all or nearly all of the time sheet records are removed. If some remain sometimes the delete will work on a single record other times it will not remove any items. I have forced the cache to update so it is not related to that.
I will go about this other ways but I would appreciate an insight into what is happening.
