My coding mask is: 00/XXXX.X.XX.XX.XX.XX.XX
The First six characters are for the Project definition.
First I created the Project definition, eg: 13/0000.
Then I created the top level WBS element which will be the same as the Project definition, 13/0000.
Then I created the 9 second level WBS elements (limit is 9 as per the coding mask) eg: 13/0000.1, 13/0000.2 and upto 13/0000.9
Then I want to create some 20 WBS elements under the first WBS element (13/0000.1). At this time the system is allowing me to create the first 9 WBS elements, i.e, 13/0000.1.1, 13/0000.1.2 and so on upto 13/0000.1.9. According to the coding mask the system should allow me to create upto 99 WBS elements at this level. But this is not happening. I am surprised. I want to know why this is happening. Please help me out.
