    Add ins are points in an objects source code where additional functions or statements can be inserted. Add ins are defined by the objects initial developer and allow other developers to easily include additional code in a subsequent phase of development without having to modify the original. Additional advantages:

    Add Ins: Definition

    z No change licences necessaryz Interfaces are upwardly compatiblez Less work at upgrade

    Requirements

    z Delivery of implemented add ins (country-specificversions, IBU solutions, partner software, ...)z Technique can be used by other software vendorsz Delivery and correction of default solutionsz Filter-dependent implementation possiblez Event-like add ins (Publish & Subscribe)z Integrated administration and documentationz Trace possibilities

    SAP AG 1998 J02 SAPTechEd 98, Karlsruhe (K. Kessler) / 24

    Why Business Add Ins?

    z Perform calls in programs / using tables Flexible Fuzzy interface (global data,...)z Customer exits (SMOD/CMOD) System infrastructure: SAP - customer Naming convention not compatible with namespace extrensionz Business Transaction Events (Open FI) No bundle of objects that belong together No interface elements

    Business add ins should be viewed as expanded and enhanced business transaction events
