3784926 - CE4JD00 select single performance degradation when table grows due to non-standard HANA index

• Performance issue in SAP standard code accessing table CE4JD00.
• Runtime of a standard SELECT SINGLE against CE4JD00 increases significantly as table volume grows (for example, ~700,000 records take ~20 seconds; higher volumes increase runtime proportionally).
• Bottleneck occurs in standard code, not in custom logic.
• Subroutine pool reference: RK2AJD00_POST – SELECT SINGLE * FROM CE4JD00.
• In one environment the API completes in an acceptable time, while another environment shows substantially longer runtimes with the same payload.

• Product: SAP S/4HANA
