Hi,

you can use the CATCH statement to handle exceptions..

Check this link for details a sample program

hi,

WORKFLOW:

Workflow is a tool for automating the business process so that the process itself flows smoothly, without bottlenecks and without dead ends. Critical parts of the process can be streamlined with deadline monitoring and contingency options. Participants are informed of milestones in the process. The process definition itself is powerful enough to allow business re-engineering with re-training and to eliminate the impact of workforce changes on the basic business process.

SAP Business Workflow is the R/3 tool for handling the process automation within R/3 or between R/3 systems and other systems involved in the business process. It is flexible enough to handle ad hoc processes such as the circulation of an electronic document. It is robust enough to handle mission critical process in the production system such as the creation of a material master.

The different R/3 applications supply standard workflows for the commonly occurring processes. Once these workflow templates are activated, they are ready for immediate use. A complete set of workflow tools, including the workflow editor and workflow generation wizard, are provided to enhance these standard workflows or create new workflows. These tools are complemented with transactions for monitoring, tracking and the statistical analysis of the processes.

Because the business process often does not step at the R/3 boundary, various interfaces and third party tools are available for extending the process across systems.

Workflow is the technique for automating business processes. It is particularly beneficial

• when different people are involved in different parts of the process

• when a process only occurs sporadically and the users need to be reminded of what they need to do

• when the duration of the process is critical and deadlines have to be met

• when the process definition is likely to change on the fly and retraining users is not possible.

By automating the process, you free the users from having to know what to do when. Work items are sent to the participants notifying them of what they have to do, and a single click on the notification calls the correct transaction and navigates to the relevant screen.

When the workflow runs it creates work items which are like e-mails, but

• they have the advantage that they contain the intelligence needed to execute the relevant task with the correct data when the operational user executes them,

• they provide their own functionality so that the operational user has access to everything that is useful to improve the flow of the process,

• they disappear on their own when they have been executed by someone else or made obsolete.

These work items can be received in the R/3 business workplace, MS Outlook (or any other MAPI compatible client), Lotus Notes, or work item notifications can be distributed by e-mail.

SAP Business Workflow:

• accelerates the workflow across applications, functional areas, organizational units, and time periods,

• supplements the integrated management of processes in the SAP System with individually tailored options for automating and actively controlling business and communication processes,

• combines integrated organizational management with flexible assignment of tasks and responsibilities to locations, positions, jobs, groups, or individuals,

• actively supports a quick implementation of workflow technologies through predefined workflow templates, Workflow Wizards and flexible adjustment options,

• integrates every employee in the value chain by providing a versatile integrated inbox ("universal inbox") at their work centers that can be configured individually,

• provides a Workflow Information System that is the foundation for process change management and continuous business engineering,

• was designed to be a change-management tool,

• simplifies continuous business engineering and process change management with user-friendly tools for defining and dynamically changing workflow tasks

• conforms to the workflow standards of the Workflow Management Coalition (WfMC)

• interfaces to other mail clients such as Lotus Notes and MS Outlook

Hi Jawad,

1.How we handle exceptions in abap?

We generally check sy-subrc value after the processing and give proper messages based on sy-subrc values.

2.What we do if something fails?

If something fail..let the user know by giving him proper message.

4. what is binding in workflow?

3.and If someone can tell me the steps of workflow?

once you call the function module

we need to use like

if sy-subrc eq '1'.

message

elseif sy-subrc eq '2'

message

elseif sy-subrc eq '3'

message

elseif sy-subrc eq '4'

message

endif

Hi Jawad,

1.How we handle exceptions in abap?

Exceptions are situations that occur while an ABAP program is being executed, in which normal continuation of the program does not make any sense. Exceptions can be raised either implicitly in the ABAP runtime environment or explicitly in the ABAP program. For example, division by zero leads to an exception in the ABAP runtime environment. It is possible to determine this situation through a query in the ABAP program and to trigger an exception there.

See the demo program DEMO_HANDLE_EXCEPTIONS in se38.

2.What we do if something fails?

here are two main types of exceptions: those that can be handled and those that cannot be handled.

· Exceptions that can be handled occur in error situations in the runtime environment or in the ABAP program, where the program can continue executing after the ABAP program has handled the exception, without the system ending up in a critical state. If such an exception is not handled, a runtime error occurs.

· The second type of exceptions are those that cannot be handled. These are critical error situations in the runtime environment. Handling with ABAP means is not possible and they always cause a runtime error.

Example for catching the run time Error :

*----

EXAMPLE FOR RUNTIME ERROR----

*DATA : VALUE1 TYPE I.

*VALUE1 = 1 / 0. "----

>>>>>> IT MAKES RUN TIME ERROR.

*WRITE : VALUE1.

*----

EXAMPLE FOR HOW TO CATCH THE ARITHMETIC ERROR AT THE RUN TIME USING SUBRC----

*DATA : VALUE1 TYPE I.

*CATCH SYSTEM-EXCEPTIONS ARITHMETIC_ERRORS = 1.

*VALUE1 = 1 / 0.

*WRITE : VALUE1.

*ENDCATCH.

*IF SY-SUBRC = 1.

*WRITE : ' IT MAKES ERROR'.

*ELSE.

*WRITE : VALUE1.

*ENDIF.

4. what is binding in workflow?

At definition time you create binding definitions for the workflow. This involves specifying the assignment rules for how data is exchanged between two containers. At runtime these binding definitions are executed making workflow execution possible.

3.and If someone can tell me the steps of workflow?

Following is link which hels you to model a workflow with an approval. This covers the important aspects and you can be familiar with Workflows at the end of it:
