The SAP error message FINS_FI_MIG703 indicates that the table ACDOCA (the Universal Journal table in SAP S/4HANA) is already partitioned, and the migration process is unable to proceed because it expects the table to be unpartitioned or requires specific partitioning settings.
Cause: Existing Partitions: The error typically arises when the migration process attempts to partition the ACDOCA table, but it has already been partitioned in a way that is incompatible with the migration requirements. Migration Settings: The migration settings or prerequisites may not have been met, leading to this error during the migration process. Database Configuration: The database configuration may not align with the expected settings for the migration.
Solution: Check Existing Partitions: Use transaction code SE14 (Database Utility) or SQL queries to check the current partitions of the ACDOCA table. Review the partitioning scheme to ensure it aligns with the requirements for the migration. Adjust Partitions: If the existing partitions are not suitable, you may need to drop
