I have an app that had 2 task to be marked as complete along with the name of the person who completed the task and a DateTime stamp
TASK1 COMPLETE (Enum with Y/N)
TASK1 Completed by (user enters initials)
TASK1 DateTime (Appforumula =NOW())
TASK2 COMPLETE (Enum with Y/N)
TASK2 Completed by (user enters initials)
TASK2 DateTime (Appforumula =NOW())
If someone completes TASK 1 and saves the record then at a later time some one opens the record and then marks TASK2 as complete then the DateTime for TASK1 is overwritten with NOW().
Is there any way to prevent TASK1 DateTime from updating if it is already set ?
