In the Management Accounting module, you can create up to 9 (nine) accounting entities using the configuration tool in Wizard format (CTBA910) and the registration routine (CTBA800), which performs the controls for the use of more than 4 (four) accounting entities.
For the Peru localization, the fifth entity (R.U.C) already exists, but it is necessary to run the wizard (U_CTBWIZENT) so that this additional entity is considered in other tables.
