Hi
1. Cost center xxxxxxx, activity type xxxxxxx: Actvty price differs fr. cost comp splt
This will be an warning I believe. If yes, no worries.
2. Cost element xxxxxx is not assigned to a cost component
I suggest to change the cost component structure as long as the system is determining correct cost element/GL. Better if you create a separate cost component for such cost elements, and in next year beginning adjust these cost elements to the relevant cost component. This way in current year your figures will remain comparable with the previous periods. However CCS should not be changed frequently but if at all required you may change it.
