Deletion of Insurance Providers 
Purpose
The system does not support the direct deletion of business partners, since this could result in data inconsistencies. For instance, you might delete an insurance provider that is still assigned to a current case via an insurance relationship.
At present, it is only possible to delete business partners which perform the insurance provider function. Consequently, you can also delete insurance providers if they also perform the Customer function and have a corresponding customer in Financial Accounting.
Process Flow
You can delete either the Insurance provider function alone, or also the general business partner together with the Customer function of the business partner, if this exists. The customer in Financial Accounting is not deleted in the process.
To do this, carry out the following two activities:
If you want to delete an insurance provider, set the deletion flag for this business partner (i.e. for the general business partner and its functions). Flagging a business partner for deletion does not restrict its use in subsequent functions.

Business partners that are flagged for deletion are no longer displayed as possible values for input in subsequent functions. If, during the patient admission procedure, you want to assign a physician to a case as the family physician, physicians who are flagged for deletion are no longer displayed when you choose
POSSIBLE ENTRIES on the Family physician field.If you want to prevent the business partner from being used at all, you also have to block the business partner.
Delete insurance providers flagged for deletionYou can use a deletion program to delete the insurance providers that are flagged for deletion, provided the insurance provider has no dependent data.
