Post-migration, your old process chains are waiting. The book provides before/after coding examples for DELETE statements in DTPs. On legacy DBs, row-by-row deletion was fine. On HANA, truncate partitions are required. The E-Bite provides the ABAP snippets for this.

| Pitfall | Solution | |---------|----------| | High memory consumption during DMO | Use –Xmx for Java export, restrict parallel threads via SUM profile. | | HANA export/import failures due to large tables | Split tables using RSDU_TABLE_SPLIT_HDB before migration. | | Mixed ABAP/Java stack (BW+Java) | Java system must be migrated separately or removed via JSPM. | | Incorrect code after migration (e.g., SELECT … ENDSELECT loops) | Run RS_HDB_MIGRATION_ANALYZE to find HANA-incompatible ABAP. | | Post-migration slow queries | Check HANA column store statistics (update with HDB_MIGRATION_STATISTICS ). | Post-migration, your old process chains are waiting

If you are on a non-Unicode BW 7.4 (common in older Japanese or Chinese deployments), the book provides a step-by-step "double migration" (Unicode first, then HANA). It advises against doing both simultaneously, as SUM often times out during the text conversion phase. On HANA, truncate partitions are required
