What is Direct Update DSO in SAP? How to Create One?

Standard DSO differs from Direct update DSO in terms of how data is processed.

In Standard DSO, data is stored in different versions Active, Delta, Modified

whereas Direct Update DSO contains data in single version. Data is stored precisely in same form in which it is written to DSO consists of Active Data Table for direct update by the application. It retrieves its data from external systems via fill or delete APIs.

The Following APIs exists:

• RSDRI_ODSO_INSERT: This API is used to Insert new data which does not exist in the system.
• RSDRI_ODSO_INSERT_RFC: This is similar to the API “RSDRI_ODSO_INSERT” except that this API can be called remotely.
• RSDRI_ODSO_MODIFY:  This API is used to modify existing records. If a new record comes in, the record is inserted.
• RSDRI_ODSO_MODIFY_RFC: This is similar to the API “RSDRI_ODSO_MODIFY” except that this API can be called remotely.
• RSDRI_ODSO_UPDATE: This API is used to modify existing records.
• RSDRI_ODSO_UPDATE_RFC: This is similar to the API “RSDRI_ODSO_UPDATE” except that this API can be called remotely.
• RSDRI_ODSO_DELETE_RFC: This API is used to delete records.
