release of your upgrade. The names of the objects that were generated before the upgrade were stored inthe REPLIST file in the current directory of your system during the upgrade (profile parameter DIR_HOME).

After selecting this task, the Selection by software components of generation setscreen appears. In thestandard setting, all software components are processed. Here you are able to restrict the amount of objectsto be generated by selecting software components. Use the pushbutton to select the software componentsyou require.

Regenerate the Objects of the Last Run

This task is suitable, for example, in the following cases:

o The generation of objects of the generation set that was used in the previous run was terminated

and you want to regenerate the remaining objects.

o You want to regenerate all objects of the generation set that was used in the previous run.

After selecting this task, the following two options are available to you:

o Resume

The generation set that was used in the previous run of transaction SGEN is used. Only thoseobjects that were not generated in the previous run or whose generation was terminated due to asystem error, are generated.

o Regeneration:

All objects of the generation set used in the previous run of transaction SGEN are generated.

Regenerate Existing Loads

This task allows you to regenerate all ABAP loads and invalidated loads that exist in your system, and togenerate loads for objects of a Support Package queue. The following options are available to you:

o Generate all Objects with Existing Load

o Only Generate Objects with Invalidated Load

The load of an object becomes invalidated if changes have been made to the object or to the objects usedby this object, since the moment the load was generated. Examples of such objects are includes and tables.This may occur by importing a Support Package (SPAM) or a kernel patch.If you want to generate loads for objects of a Support Package queue, start the task after importing thequeue. The task determines the generation set using the invalidated loads in the system. In contrast with theGenerate objects of a transport requesttask, this task also takes into account ABAP loads that wereinvalidated by modified Dictionary objects.

After choosing this task, a screen appears which allows you to search for the name of the transport requestusing the selection button, or to specify it directly.

Generation of BSP Applications

This task enables you to generate BSP applications of selected software components.Each Business Server Page is realized technically through an ABAP object class. When BSP applicationsare generated, these classes and their ABAP loads are generated. BSP applications are not included in thegeneration sets of the Generate All Objects of Selected Software Components, Regenerate After an SAPSystem Upgrade and Regenerate All Existing Loads tasks, since they are optional. You can use this task todeal with these.

After selecting this task, the Selection by software components of generation setscreen appears. Here youcan restrict the number of BSP applications to be generated by selecting software components. Use thepushbuttons to select the software components you require.

If you quit the generation of BSP applications before it has finished, or if the system terminates generation,the Regenerate the Objects of the Last Run task allows you to resume the generation.

2. Select Server for Parallel Generation.

The generation is based on a parallelized method, where the generation set is divided into small subsets that are

processed by parallel processes. Depending on resources, available servers are included in the parallel processing,whereby multiple parallel processes run on one server.

From the Selection of Server for Parallel Generation screen, you can select the servers that are to be used in theparallel processing. Note that loads depend on the machine type (MT) of a host. This means that it only makes senseto parallel process the generation set of servers of the same machine type.

The default selection orientates itself by the server to which it is logged on. It corresponds to your logon server and allservers on your system that have the same machine type. If you want to use the default selection, choose Continue.

If you want to exclude individual servers from the generation, or if you want to generate the load for a particularmachine type that is different to that of the logon server, then use the pushbutton to select the corresponding serversand choose Continue.

Note: The parallel servers are depicted via the logon groups in transaction RZ12. For transaction SGEN, logon group'parallel_generators' is created. Do not use this group for your own purposes, as transaction SGEN uses andcontinually redefines this group.

From the selection of the servers, the system starts to automatically define the generation set, and to store it on thedatabase (DB tableGENSETC). This may take several minutes.

Job MonitorPushbutton

This function allows you to call the job process control directly without having to redefine the generation set. Bychoosing Job Monitor-> Job Overview-> SpoolorJob Log, you can display logs from previous generation jobs.
