3789848 - Poor performance in BOP if running with PAL - Performance trace analysis indicates the longest time is taken in CL_ATP_PAL_CHECK_BADI_ADAPTER

• Backorder Processing (BOP) with Product Allocation (PAL) active shows slow performance and long runtime in aATP.
• Performance trace (for example, SAT) indicates a hotspot in class cl_atp_pal_check_badi_adapter.
• The longest time is consumed in method IF_ATP_PAL_CHECK_BADI_ADAPTER~ADAPT_PARAMS_AND_TIME_SERIES or method TMESERS_MAP_TO_CHECK_PARAMS.
• The issue is observed when running a BOP variant for orders where PAL is enabled.

• Product: SAP S/4HANA
• aATP components: Product Allocation (PAL) and Backorder Processing (BOP)
• Scenario: BOP run with PAL active in aATP
• Analysis tool: SAT performance trace used to identify hotspots
• Technical objects: class cl_atp_pal_check_badi_adapter; methods IF_ATP_PAL_CHECK_BADI_ADAPTER~ADAPT_PARAMS_AND_TIME_SERIES and TMESERS_MAP_TO_CHECK_PARAMS
