what's the usage&purpose of statistical wbs?
in our project, the wbs structure is as follows:
project definition (wbs)
first level wbs (wbs)
second level wbs (wbs-1)
third level wbs (wbs-1-1)
all of them, only the first level wbs is statistical and they use substisution to ensure that when you save the project the first level wbs is statistical and can't be changed.
In PS module, i can maintain the wbs settlement rules except the statistical one . i can CJ88 the project to settle.
I don't know the purpose of setting the first level wbs a statistical. It seems no difference from the normal settings.
Is that proceed from FI-CO purpose?
can anyone explain? Thanks very much!
