## 13.2.7.3  Deletion of Personal Legacy Data After Migration from Classic Real Estate Management
You might still have legacy data from the classic SAP ERP component Real Estate Management (RE) that is subject to the data protection laws applicable in specific countries as described in SAP Note 1825544 .
The SAP Information Lifecycle Management (ILM) component supports the entire software lifecycle including the storage, retention, blocking, and deletion of data. You can use SAP ILM to support the deletion of personal data as described in the following sections.

## Process Flow
1. Before archiving data, you must define residence times and retention periods in SAP Information Lifecycle Management (ILM) by doing the following:
- Run transaction IRMPOL and maintain the required residence and retention policies for the Real Estate Business Partner (ILM object: TRTM\_BPAR ).
- Run transaction IRMPOL and define the required retention policies for the ILM objects of Real Estate Management (RE).
- You choose whether data deletion is required for data stored in archive files or data stored in the database, also depending on the type of deletion functionality available.
2. To determine which business partners have reached end of purpose and can be archived, you do the following:
- Run transaction SARA and call up archiving object TRTM\_BPAR .
- Specify the Real Estate Business Partner you want to archive in the write variant of the archiving object. Before archiving, the write program checks whether business partner data is still used by the relevant objects in Real Estate Management (RE).
- If the business partner data is no longer used in ongoing business activities, i.e. all related Real Estate objects were either archived or the assignment of the business partner to the relevant Real Estate object was removed, the business partner is archived and thus blocked in the system. Only users with special authorizations can then access the archived data.
3. To delete personal data, you do the following:
- Run transaction IRMPOL for the ILM objects of Real Estate Management (RE).
- Run transaction IRMPOL for ILM object TRTM\_BPAR .
