SAP MDG · REPLICATION OUTBOUND
How do I implement an SAP MDG DRF outbound filter class for business partner replication?
Implement IF_DRF_FILTER~APPLY_FILTER to read the custom filter configuration by replication object and business system, extract the first field of each outbound object row, and delete rows whose rule has SIGN = 'E'. For BP-specific scenarios, extend the same pattern with vendor/customer account-group enrichment from memory or master data before applying the exclusion list.
SOLUTION SUMMARY · SHORT ANSWER
Implement IF_DRF_FILTER~APPLY_FILTER to read the custom filter configuration by replication object and business system, extract the first field of each outbound object row, and delete rows whose rule has SIGN = 'E'. For BP-specific scenarios, extend the same pattern with vendor/customer account-group enrichment from memory or master data before applying the exclusion list.
In SAP MDG DRF outbound filtering, the core pattern is configuration-driven exclusion inside IF_DRF_FILTER~APPLY_FILTER. The class ZCL_DRF_BP_FILTER reads ZMDG_DRF_CONFIG by replication object and business system, dynamically reads the first component of each filtered row, and deletes matching rows when the config line is marked for exclusion.
Process flow
- Implement IF_DRF_FILTER in the class and code the logic in IF_DRF_FILTER~APPLY_FILTER.
- Read ZMDG_DRF_CONFIG by FOBJ and IV_BUSINESS_SYSTEM.
- Loop over ET_FILTERED_OBJECTS and use ASSIGN COMPONENT 1 OF STRUCTURE <fs_struc> TO <fs_obj_val>.
- Convert the extracted key to the comparison type used in the config table.
- Read the config line by VALUE and delete the row when SIGN = 'E'.
- For BP-specific variants, derive KTOKK or KTOKD from memory or master data before filtering.
- If using specialized vendor/customer config, subtract those values from the main config before looping.
- Keep the base filter as fallback when specialized context is not available.
