9.List the various advantages of SAP Business Workflow
Workflow provides numerous advantages to SAP users and consultants:

  1. It allows consultants to create new business processes without modifying the standard SAP code.
  2. Workflow ensures that the tasks are executed in the correct sequential order, involving the relevant personnel.
  3. SAP Business Workflow may be run through the internet or intranet web applications via the Webflow Engine.
  4. Deadline Monitoring functionality is also incorporated within SAP Workflow.
  5. The timely execution of activities is guaranteed even when a number of parties (users) are involved.
  6. Workflow reduces both time and expense involved in managing business activities.

10. What is a work item ? How does it differ from a simple SAP office mail item ?

  • A work item is a runtime object generated by a step within a workflow. Whenever user interaction is required, the respective users are informed via work items. These work items will be received by the user in their Business Workplace inbox, or other email application such as Microsoft Outlook&rights;
  • The work item may be a user decision or a dialog form that allow you to enter data for starting a process within SAP, or a confirmation of whether a particular task may be performed. The user then chooses an appropriate option which determines the subsequent behavior of the workflow in question. There are a variety of applicable work items. Each work item has a status reflecting the stage of processing at any given point in time.
  • A work item comprises of text explaining what action needs to be taken, whom to refer to and any information pertinent to the business object involved.
  • Unlike simple SAP office mails, work items are active entities, as they determine the subsequent direction of the workflow. SAP office mails can also be deleted from the inbox without viewing them whereas a work item has to be executed to have it removed from your inbox.

11.What is a background work item ? Are they displayed in the Business Workplace ?
A background work item (code B) represents tasks that do not require any user interaction. They are controlled and executed automatically by the workflow system, and do not appear in the Business Workplace. However, you may view them using the Work Item Selection Report.

12.Which method is executed if space is passed for the method parameter of macro SWC_CALL_METHOD ?
The Default method of the object type is executed if a space is passed as the method parameter value. You can find the default method by viewing the applicable object using transaction SWO1 and going to menu option “Goto -> Basic Data” and clicking on the Defaults tab. The default method is located in the field “Method”

13.What are the different types of WF Agents?
1.Possible Agents
Users who are authorized to execute the task
Configured during Task definition (Org Unit, Position, User, Work Center, Role, Rule)
If a Task is configured as General Task, then all users become possible users.

2.Responsible Agents
The users to whom the work item needs to be sent.
This is set during Step definition. Note that Possible agents are defined during Task definition. (Org Unit, Position, User, Work Center, Role, Rule, Container Element)
Note: The work item recipients is determined by intersection of Possible Agents and Responsible Agents.

3.Actual Agents
Actual user who executed the dialog task

4.Excluded Agents
Users who are not supposed to execute the dialog task (even if they are in possible agents)

14.What are the agent determination techniques?
Rule Resolution with responsibility: Helpful when a set of static positions are responsible for action.
Rule resolution with Function (FM): Helpful when agents are determined dynamically from business logic.
Rule resolution with OM: Usually used in CRM. Have not used
Rule resolution with Function, but asynchronously: This is through a class and a method. Initially WI is created in status ready without agent. Later agent is assigned. This is suitable for agent determination having complex logic.
Users: Rarely used.
Role: Ex: ABAP_DEVELOPER
OM objects (Position, Org Unit, work center)
Expression: A container element containing the agents.

Function Module that creates workflow
SAP_WAPI_START_WORKFLOW:
SAP_WAPI_CREATE_EVENT
SAP_WAPI_WORKITEM_RECIPIENTS
SAP_WAPI_GET_WORKITEM_DETAIL

20.When a infotype action is performed, an FM should trigger, and a workflow subsequently. How can I configure it?
Tcode SWEHR2

21.Workflow is not triggering… what can be the reason?
What are the different ways of triggering a workflow?
Triggering Events, which are set up in SWE2 (generic), SWEHR2 (HR)
SAP_WAPI_START_WORKFLOW

22.Workflow triggered, but it did not come to the user, why?

23.What are the difference between a Business Object and a Class?

24.How to achieve dynamic parallel processing?
There are three ways a parallel processing can be implemented

  1. Dynamic parallel processing using a multi-line container element
    Fork (3 out of 5)        Work queue
  2. In dynamic processing the type of each entry in the table have to be of same type.
  3. Same task will be processed for each line of the multi-line container. It can be a dialog or background task. Deadline monitoring, binding, agent determination will be same for each work item generated To achieve, go to “Miscellaneous” in the activity, and enter the multi line container element.

25.How to notify a user immediately in R/3 that he has got an email?
Mark the priority as ‘1’ Express

26.How can we debug a workflow?

  • If it is a dialog task, you can set breakpoint in the method called by the task
  • If it is a method that you want to debug, use SWO1, and create a instance of the object and debug the methods
  • If it is a background task, and you are in development client, you can do the following. Create an infinite loop in the method you want to debug. Go to SM50 (processes overview) and select the relevant item, and select debug from option.

26.Huge number of events is getting created in a short duration of time, and thus creating a huge load on the system and making it very slow. Solution?
Enable event queue. It will ensure that triggered events are received in a phased manner. This needs to be done while providing event linkages.

27.What is the integration point with ESS Portal?
Tcode SWFVISU
Portal config file for UWL

28.What are the different statuses of a work item?

  • Waiting
  • Ready
  • Reserved
  • Inprocess
  • Executed (‘confirm end of processing’ in task definition)
  • Completed
  • Logically deleted
  • Error

29.Difference between Asynchronous and Synchronous methods in a task
A work item created as part of synchronous in locked until end of the method execution. But in asynchronous, work item is locked only until start of method execution.
At least one terminating event is required for a task using Asynchronous task

30.What is the use of secondary methods in an Activity?

  • A modal call
  • Before work item executing
  • After work item execution

31.What is the BO method called for the task which calls UWL WD screens? Why?
EXTSRV –> PROCESS

32. What is the use of “Advance with dialog”?
If this indicator is set for an activity, workflow system checks if the processer of current task is also a recipient for next task. If yes, then the next task will be executed immediately.

33. Difference between Search Helps and Match Codes

  • search help: adding f4 functionality is search help(adding help for any topic)
  • match code: adding search help for the input field is called as math code object

34. Name the tables used for storing the event linkages ?
SWETYPECOU – Type Linkage Table
SWEINSTCOU – Instance Linkage Table

35. What are the types of work items?

  • Dialog Work item – W
  • Background work item
  • Workflow work item
  • Work queue work item
    Missed deadline work item: When a deadline is missed a missed deadline workitem with the message appears in inbox

36. Why ‘Process Control’ is used? What are its features?
‘Process Control’ is used to manipulate another work item of the workflow during runtime.
‘Process Control’ is usually used to model the workflow when deadlines are reached. SAP offers 4 standard behaviors as part of process control.

  • Cancel Work item: Target WI is logically deleted. Subsequent tasks are not executed. Precondition is that Process control and the target WI have to be in different branches of the same fork.
  • Set Work item to obsolete: The target WI is set to complete, and processing continues in the branch processing obsolete.
  • Cancel Workflow: Current workflow is set to ‘Complete’. If this is the sub workflow, then the control goes to super-ordinate workflow.
  • Complete (terminate) Workflow: Same as above, but the branch of super-ordinate workflow which contains the current sub-workflow will not be continued.
  • Cancel Workflow including all callers: Same as above, but all callers also will be ‘COMPLETE’d.

37.When a infotype action is performed, an event should trigger, and a workflow subsequently. How can I configure it?
Tcode SWEHR2
