Implementing Your Own Process Type (SAP Library

Implementing Your Own Process Type

Purpose

If you:

· write your own application log to be displayed in the Process tab strip for the Logs for a Process in the Process Chain Maintenance, or:

· if you have implemented your own monitor, or

· have implemented a Customizing interface that goes beyond the parameters of a program, or

· want to access preceding chain processes in your program, or

· want to take errors when executing your program in modeling into consideration or you know multiple end states (see process type Decisions)

we recommend that you implement your own process type.

Prerequisites

You need to have a good knowledge of the ABAP object-orientated language enhancement - ABAP Objects.

Process Flow

...

1. In the menu, choose Tools → ABAP Workbench →Development → Class Builder

Note

You can find additional information about the Class Builder in the SAP Web Application Server documentation under BC - ABAP Workbench → ABAP Workbench: Tools → Class Builder.

The following IF_RSPC_* interfaces are available:

Interface IF_RSPC_*	Description	Method is called in ...	Implementation is ....
EXECUTE	Executes the process. This interface is the main interface used to implement your own process type and is the only process chain maintenance interface that is obligatory.	Runtime	Required
GET_INFO	Transfers the information for a process to the successor.	Maintenance and runtime	Optional
GET_LOG	Returns the log for a variant and an instance to the process chain maintenance, either as a title and text or as a list of messages	Runtime and log view	Optional
MAINTAIN	Enables process variants to be created and maintained in the process chain maintenance. It also determines the header information for a variant so that it can be displayed in the process chain maintenance.	Maintenance	Alternative or in addition to interface IF_RSPC_GET_VARIANT
GET_VARIANT	Provides value help (F4) for variants. You need to implement this interface and/or interface IF_RSPC_MAINTAIN, in order to be able to add process variants to a chain.	Maintenance	Alternative or in addition to interface IF_RSPC_MAINTAIN
GET_DEFAULT_CHAIN	Gives the default chain for a process. You can suggest, for each variant to be scheduled, which additional process it would make sense to schedule before or after the process.	Maintenance	Optional
CHECK	Consistency check at scheduling time for the process/chain You can carry out a check to determine: · the consistency of a process · the dependency on other processes in the same chain and · dependencies on other processes in other chains. · authorizations of current user to execute process	Maintenance	Optional
GET_STATUS	We recommend you implement this interface for distributed processes. Distributed processes, such as the loading process, are characterized as having different work processes involved in specific tasks. The interface allows you to request the status of the instance in the process chain maintenance(for distributed processes when follow-on events are not sent). Therefore, the system can also recognize terminations even for distributed processes.	Runtime and log view	Optional
CALL_MONITOR	Calls up the process monitor from the log view in the process chain maintenance.	Log view	Optional
TRANSPORT	Returns TLOGO entry.	Maintenance	Optional
CONTEXTMENU	Adds some functions to the context menu for a process in the process chain maintenance.	Maintenance	Optional
VARIABLES	Declares if the process can process runtime variables	Runtime	Optional
SIMULATION	Passes on and displays the simulation results	Runtime	Optional
MULTI_EVENT	Declares the possible end states of the process	Maintenance and runtime	Optional

You can find further documentation for the IF_RSPC_* interfaces under Tools → ABAP Workbench → Development → Class Builder . For Object Type, enter the interface name and choose display. You can access the documentation in the subsequent screen using the Jump menu.

2. Enter the process type under Settings → Maintain Process Types (RSPROCESSTYPES view) in process chain maintenance..

Then choose Edit → New Entries, allocate the technical name, short and long description for the process type, enter the name of your class and choose ABAP-OO Class as the Object Type. Make the other settings for your process type and save the entry.

3. If using the service class CL_RSPC_APPL_LOG, enter your process type as a sub-object to the log object BW_PROCESS.

Result

Your process is available in the process chain maintenance of the process category you assigned.
