Testing and Debugging Workflows

Workflow/WebFlow Track ³Where making your work flow is our business´




Testing and Debugging workflowcan be a very challenging task.

My goal here is to help you identify

the tools to complete that task.




Testing and Debugging Workflows

Business object builder - Attributes- Methods

Events ± Event linkage- Event test tools- Event check FMs, receiver type FMs

RolesWorkflow analysis ± Diagnostic tool




Debugging With BOB

Pick the attribute or method you need todebug, and push the

µProgram¶ button to get tothe ABAP code«




Debugging With BOB

Place the cursor on thecode you are interested

in, and set the

breakpoint




Debugging With BOB

Set the debugger

on and use thewrench




Debugging With BOB

Push µInstance¶




Debugging With BOB




Debugging With BOB




Debugging With BOB

Just push the µgo¶ iconfor the method you

need




Debugging With BOB

Don¶t forget to push theDebugging Button




Debugging With BOB




Debugging With BOB

Set a breakpoint in the code of attribute (or method), before things really get µinteresting¶

If you have calls to macros (swc_get_element, etc)you *may* need to set the values of the resultelements inside the debugger (for example, whengetting an element from the workflow container)

You can then step through debugging the attribute or

method as you would any other ABAP code

You probably want to step OVER the macro calls.They can be mildly disturbing, and it serves no

purpose to go there.




Debugging Events

Event linkage in the workflowEvent linkage (SWETYPV)Event creation (SWUE)Simulate event (SWU0)Check the event log (SWEL)RFC queue (SM58)




Event Linkage in the Workflow Definition

This is the event you wantthis workflow to start with

Always check your binding to

the event




Event Linkage With SWETYPV

The checkbox tells youthis event is linked to a

workflow, well, sort of«




Event Linkage With SWETYPV

Workflow Name

Note thatthis is

ACTIVE




Check FM or Receiver Type FM ?

A check function module can be used tosimply abend if the object does not meet thecriteria for your workflow (i.E.: It¶s not the

correct document type)A receiver type FM can be used todynamically determine which of a number

of workflows should be called based onobject attributes (much more efficient thanmany check FMs!)




Event Triggering With SWUE

Use this flag to startthe ABAP debugger

Fill in the Object Key of theobject you are working with









Set the breakpoint in your receiver FM first, then

when you check µTrigger FM synch¶, you will get

to your breakpoint




Event Simulation With SWU0




Event Simulation With SWU0

Check the statuses of theworkflows.






Errors in the Event Log (SWEL)




Errors in the Event Log (Drill Down)

Now, at least I knowwhere to begin

debugging again




SM58 (or Program RSARFCRD)




Errors in the RFC Queue




What Is the Event Passing ?

What Is the Event Passing ?

These are thecontainer elements

passed by the event




Workflow Did Not Start

If the event was triggered, but the workflowstill did not start, it is likely the object doesnot yet exist in the database. In this case,

you may need to use other methods to getthe object information into your workflow(while the database commit gets

performed).Use the event simulation transaction(SWU0) to see which workflows are linkedto the event, and what their statuses are.




Role Resolution ± Who¶s Got the Workitem ?

Function Module to be

executed to determinewho the agent of this

workitem is

I like this, because I¶drather get an error, then

have the whole world getthe workitem!

This icon will simulate therole




Simulating the Role Resolution

Fill in your objectattributes (requiredimport parameters)

Then push thewrench to see if your role returns

any agents




Debugging the Role Resolution FM

Go to SE37 and enter your function modulenameChoose the wrench (µtest/execute¶) tool

On the next screen, push µdebugging¶You will be taken into the ABAP debugger Note: you will not have the µworkflowcontext¶




Debugging the Role Resolution FM

You will need to setthese values after

control returns fromthe macros




The Diagnostic Tool, SWUD

The options from here are:Verify workflow customizing

Debugging Workflow (the Hard Way)Also Known As µIf All Else Fails¶

Sometimes, you still can¶t tell why aworkflow is/is not being triggeredOr, the workflow is triggered, but

immediately failsThere may be synchronizations problemswith the database, for one

Try inserting code into your check functionmodules, receiver type function modules,role resolutions, methods, etc
