Currently in PDMLink 10 M030, the management of Start/end incorporation dates of the Part Instances objects is such that End incorporation date must be strictly superior to the Start incorporation date.
Actually, the fact that End date may occur later than the Start date is a common sense statement.
But there are cases in the industry where the use case might be sligthly different.
Sometimes, Part Instances are used to figure out the use of real parts assembled on a prototype assembly.
This prototype may sometimes be built, tested and modified in the same date : same day.
For example, for prototype test purpose, it is possible that the test team would assemble a prototype stuff with a given tested part and would then have to changed it for another alternative tested part in the same day.
As a matter of fact, the tested part would have been incorporated and de-incorporated in the same day : this is something that the application(PDMLink 10 M030) does not allow or is not able to trace.
The purpose of the current idea would be to enable the following statement :
on the Part Instances objects, the definition of the Start and End incorporation dates would be such that End date can be equal or superior than the Start date.
