Account concerned is defined as a cost element.  An account assigned as cost element must contain a real CO Object.

Account assignment objects in Controlling are orders, cost centers, projects, cost objects, networks, special make-to-order sales orders, and profitability segments. The most important rule is that for each posting line to an account that is also created as a cost element in CO a real CO account assignment is required.

In general this means that the transaction that is executed is responsible for sending an account assignment to the CO interface in order to avoid error KI235. So if you would expect that an account assignment should already be included for example in a goods issue or an invoice, then the root cause for the error message is not within CO but with the goods issue or invoice itself.

There are however several possibilites to let the system automatically determine an account assignment within the CO interface.

The following is the order of steps taken in the CO interface to determine the account assignment:

1. If the sending transaction provided an account assignment to the CO interface for the line item this account assignment will be used
   
   
2. CO Substitution:  See help.sap.com documentation Substitution/Validation for Journal Entries
   
   App Manage Substitution/Validation Rules (App ID: F4406) Business Context: Coding Block -  No overwrite mode
   
   App Custom Logic (App ID F6957) BAdIs for Substitution for Journal Entries: FIN_CODING_BLOCK_SUBSTITUTION
   Be aware that the substitution can potentially change or remove exisiting account assignments as well.
   
   
3. Default Account Assignments via SSCUI ID 102639 / Configuration Activity 'Manage Default Account Assignments' (Only if still no valid account assignment exists for the line item at this point the system will use the account assignment from the default account assignment)
   
   In your app Manage Your Solution, Choose Configure Your Solution (or CBC System)
   Enter
