If changes are made to business partner master data, this can have an effect on dependent objects. If, for example, bank details are entered in a contract account for a business partner, and these bank details are deleted from the master record of this business partner, the contract account contains bank details that no longer exist. This indicator is used to carry out a check for such dependencies. If it is set, dependency checks are carried out when changes are made to a business partner. If a dependency exists, a dialog box appears which you can then use to remove the dependencies. Among other things, the system test whether deleted bank details, credit card details, or addresses are still being used in a contract account. The system also tests whether an address that contains a tax jurisdiction code was changed.
