Select a valid unit
Each time I try to create an initiative the system stops responding with the error "select a valid unit" .
What is wrong with the customizing?
Please check whether you have maintained the correct units in the customizing in the path
SAP Portfolio and Project Management->Project Management->Basic Settings->Define Time Units.
If the units are correctly maintained, then while creating the initiative, in the tab capacity information, you have to select a unit, especially if you are maintaining other fields like actual work effort.
Hope this helps.
