Use

Load generation requires a large amount of system resources. There are several ways to create loads after the update, depending on the way you use the SAP system.

• For objects that are new in the SAP system after the update, you can use transaction SGEN to create the following loads:

  • ABAP programs in the SAP system

    When you call an ABAP program, a load is automatically generated if it does not already exist for this program. This may, however, impair performance in a production system. To avoid this, you can generate the missing loads using the option Regenerate after an SAP System upgrade in transaction SGEN before you use the system in production operation.

  • Business Server Page applications (BSP applications)

    If you plan to implement BSP applications in your SAP system, you can generate them with the SGEN option Generation of BSP Applications.

  • Web Dynpro applications

    Select the SGEN option Generation of Web Dynpros.

  Transaction SGEN offers the following functions:

  • Selection of predefined generation tasks

  • Selection of software components (such as SAP_ABA, SAP_BASIS) to restrict the amount of objects being generated

  • Selection of the application servers for parallel generation

  • Generation in the background

  • Job Monitor for checking the progress of the generation in the background

• If you want to regenerate invalidated loads after the update, you can use report RSGENINVLAS (until SAP Basis 7.02 SP08) or RSGENINVLASM (as of SAP Basis 7.02 SP09). This report regenerates all invalidated ABAP loads for every machine type that exists in your system.
