When there is memory limitations in SAP, we may not be able to define high number of dialog or back ground processes. Operations modes are a concept provided by SAP to take advantage of this fact.

System will switch to day or night based on the settings and improve the system performance.

      Hello Arun,

      Would not make sense to change the number of DIA and BP for day and night operations?
