HANEYA identifies the inconsistencies based on the new Business rule set, Data model changes, and Business Process changes in S/4 HANA. In all the cases, we review the master data inconsistencies by each object. There three types of inconsistences, we derive suing HANEYA tool – inconsistencies with existing data based on the proven business rules, changed fields / data elements - new data model with changed tables from ECC to S/4 HANA, and New fields introduced in S/4 HANA. The resolution is three fold: business rules inconsistencies are resolved by Automation, while changed fields and new fields are resolved via guided master data process.
