Working with Container Operation and Loop (Until) Steps - PART2

Note: 

1. Before reading this document readers must study Part 1 of this document. i. e.( Working with Container Operation and Loop (Until) Steps - PART1 ).
2. This document will help us to learn how to execute and analyze a workflow.

Steps:

1. In Part 1 of this document we have seen how to build a workflow with Container Operation and Loop (Until) Steps.

2. After completely Building a workflow we can start our execution process.

• We have to press execute button(F8) to run the workflow.

3. Now we can see a screen as shown below.

4. This screen consists of the following tabs.

•      Input Data Tab.
• Here we have to fill in the importing input parameters.
• _wf_initiator , _wf_priority and _wi_group_id are default parameters.
• lv_counter  is the parameter created by us for keeping the loop count
• (This is discussed in Part 1 document->‘ABAP Workflow For Beginners: Working with Container Operation and Loop (Until) Steps-PART1’)
• We can change the value of the ‘lv_counter’ parameter to our desired value.

5. Now we have to press on Execute(F8) to start workflow processing.

• We will get the following status message.

6. Now as we have started the execution of our workflow we have to follow steps to analyze the execution of it as shown below.

   

• Graphical Workflow Log:
• This will display a graphical representation of the process flow of our workflow.
• The green path will show the step-by-step execution of the workflow.
• Here we can see that first the loop step will be executed.
• And then the container operation step will be executed, here the decrement of the value of the ‘lv_counter’ element by 1 is performed on every loop execution.
• Then the next step to execute will be the ‘send mail’ activity.
• After the ‘send mail step’, the loop will continue to execute until the ‘lv_counter’ element’s value will be ‘0’.
• Once the ‘lv_counter's value is ‘0’, the loop ends and workflow completes.    

• Workflow Chronicle log:
• This log consists of a tree view(technical Details) of the steps executed in a workflow.
• Here in the below figure, we can see that five loops have been executed.
• This is because our ‘lv_counter’ value is ‘5’ and the loop step will loop until the ‘lv_counter’ value is ‘0’( This is discussed in the Part 1 document).
• With the execution of each loop, the ‘lv_counter’ Value will be decremented by 1(That is why the loop will end after 5 executions).

1. In technical details (Tree structure) we have 6 tabs.

• Details tab: 
• Has details like workflow task ID, Work item status, date, time, etc.

• Step History tab: 
• This is a step-by-step error detail.
• There are no errors in our workflow execution, that is why ‘Execution Action’ is in green status.

• Deadlines tab: 
• This step shows the deadline details for the steps used(example mail step).
• We have not set any deadlines so this tab has no entries. 

• Task Description tab: 
• This step shows the description of the tasks that are used in our workflow.
• For example: Send Mail step body content. 

• Container tab: 
• This tab consists of the container elements with their runtime values.
• For example:’lv_counter’ value will be  ‘0’  after completion of the workflow execution as shown below.

• Message tab: 
• This tab displays work item-wise message details.

2. SAP business workplace: 

• Sap business workplace (T code SBWP) is a place, where we can view the emails triggered by a workflow as shown below with recipient specified as our SAP login ID.
• As we can see ‘5’ unread mails are displayed in the ‘Inbox’.
• This is because the ‘send mail step’ is created inside the branch of  ‘loop until step’ and the ‘loop until step’ will be executed 5 times.
• And the mail recipient is ‘WF_INITIATOR’, that is why the mail is sent to our ‘Inbox’.

      

• After opening the mail we can see the following details.
• Subject, the body of the mail, and recipient details will be displayed.

7. This ends the detailed explanation of the execution of workflow( Creation is explained in Part 1).

Conclusion: Now we know how to execute a workflow using step types: loop(until), Container operation and Send Mail.
