The following screenshot is the current status of the code part setup.
Please note that currently these code part values are used and all the transactions are linked to cost centers.

For the requirement of using cost center on serial and functional objects, we have to change the  “Code part B”>Logical Code part value to "Cost Center" in the below setup.

Since we are already using cost centers as mentioned above what is the overall impact on the system when we change the code part setup?
