3804513 - CL_SDM_FOT_RECON runtime estimation and HANA partitioning prerequisites

When planning or executing an S/4HANA upgrade on a system with large Financial Accounting (FI) data volumes, one or more of the following situations occur:

• There is no reliable method to estimate how long CL_SDM_FOT_RECON will take in SUM post-processing before the production upgrade window is committed
• CL_SDM_FOT_RECON completes significantly later than the upgrade window allowed for SDMI post-processing
• Increasing the number of parallel processes in SDM_MON does not reduce the runtime or improve throughput
• The question arises: is table partitioning on BSEG and BSET required before running the upgrade, and how does it affect SDMI performance?
• BSET contains more than 2,100,000,000 entries and the risk of a hard migration failure needs to be assessed

• SAP S/4HANA on-premise
• SAP S/4HANA Private Cloud Edition (PCE / RISE with SAP)
• S4CORE 108 and higher (including S4CORE 109)
• SAP_BASIS 755 and higher (including SAP_BASIS 816)
• SAP HANA 2.0 (all SPS)
• Applicable during SUM ABAP standard upgrade to S/4HANA 2023 or higher (S4CORE 108+
