transaction MB90 (report MM70AMEA)

  • You have activated the business function Materials Management, UI and Performance Optimizations (LOG_MM_OPTIMIZATIONS).

  • You have performed the following activities in Customizing for Materials Management under Start of the navigation path General Settings for Materials Management Next navigation step BAdI: Activate MM UI-Related Performance Optimizations Next navigation step and Next navigation step BAdI: Activate MM DB-Related Performance Optimizations End of the navigation path.

Features

The business function enables two kinds of improvements:

  • UI-related performance improvements are enabled by activating the implementation of BAdI: Activate MM UI-related Performance Optimizations (MM_UI_OPTIMIZATIONS).

    There are transactions that display the data with single or multiple list lines. In cases where large amounts of records are displayed, especially with colored list lines, it takes up a significant percentage of the overall runtime. The runtime to display the data can be decreased by changing the UI to an ABAP ALV Grid-based single-line data output. This decreases the overall runtime of the transaction.

  • database-related performance improvements are enabled by activating the implementation of BAdI: Activate MM DB-related Performance Optimizations (MM_PERF_OPTIMIZATION).

    In some cases an optimization may have an overall runtime which is slower on other databases than prior to the optimization. This may be due to complex join operations on non-indexed fields or due to a change when data is read from the database. An example is a one-step procedure as opposed to a two-step procedure.

Note Note

SAP recommends to test which data access is faster for your system and to use the faster alternative. The business function is fully reversible; therefore, you can deactivate the business function after a trial in your test system if the classic approach is more convenient for you.

End of the note.
Restrictions

The two optimization approaches (UI or database-related) are only possible for the following transactions of the Materials Management component (MM):

UI-related performance improvements:
  • MB5B (report RM07MLBD)

  • MBLB (report RM07MLBB)

  • MB58 (report RM07MKON)

  • MB5M (report RM07MMHD)

  • MI24 (report RM07IDIF)

  • With SAP enhancement package 7 for SAP ERP 6.0 (SAP_APPL 617), the transaction MB90 (report MM70AMEA) is introduced with UI-related performance improvements.

Database-related performance improvements:
  • MB5L (report RM07MBST)

  • MB25 (report RM07RESL)
