Hi @Mehdi 

maybe this screen will help you.

Hi Mehdi,

Code String is used to define how the company uses code parts when creating financial transactions. The products in IFS Applications can use 10 code parts.

One or more code parts can be used for creating postings. Each code part has an internal part, which can be translated.

- Code part A is always the account code part used in the general ledger. It must always be available for use. 
- Code parts B-J are optional and can be defined by the user. Depending on the components installed, an optional code part can be used for a special function such as current balance, internal elimination, FA accounting, project accounting, consolidation, or internal. These code parts can be specified as available or not available in the company.

Code Part Values window is used to enter, change, or view the values of the free code parts B-J.

Hope this gives you some explanation on different types of code parts.

Thank you.

Best regards,
