I am planning to manage the asset under construction (AUC) by the PS module. This means to create the AUC through the WBS element, and finally settle to the final asset. For doing that I understand that the asset under construction class should be created as an investment measure.
I am asking if it is necessary to implement the IM module to manage the AUC by PS module.
If it is not necessary which is the difference of having IM implemented?
