How To Use Process Execution Manager Using SAP TDMS 4.0

October 2012

1

1. Business Scenario

SAP TDMS run requires constant monitoring and manual intervention. The Process Execution

Manager (PEM) is a funtionaility of SAP TDMS that minimises the overall manual intervention

needed to execute a TDMS run. The PEM consist of a Plan, Groups, and Blocks. The PEM Plan

represents the process tree with focus on executable activities. Non executable activities will not be

considered for the PEM Plan calculation. SAP TDMS offers a default PEM plan for every migration

solution based on the sequence and interrelationships of activitiies.

The TDMS process structure helps you execute specific activities in a TDMS migration package and

track the activity status.

2. Background Information

The Process Execution Manager (PEM) helps you to carry out an optimal execution of SAP TDMS

with minimal user interaction.

3. Preconditions:

You have carried out the following activities:

Created a project

Assigned a system landscape

Loaded a migration package

Switched to the Process Execution Manager tab page.

3.1 The Process Execution Manager (PEM)

The PEM creates a processing plan based on the process tree, the process phases, and the process

activities. The processing plan aims at an optimal level of processing with minimal user interaction,

while taking into consideration the interrelationships between activities. You can view the plan

calculations in the Plan view.

The process tree is divided into groups and blocks. Groups contain blocks and blocks contain

activities.

All groups belong to a Plan. One or more groups correspond to a phase (known from the process

tree/process structure).

A block can be dialog or batch. A batch block is performed without user interaction. Dialog blocks

require user interaction if they are not optional.

In the following pages, we demonstrate the processing of a solution/package serving as a model to

show what you have to do to process the PEM and what user interaction is expected from you.

You are in the process tree of your package. After calling the Package overview, the Process

Structure tab page appears. Switch to the Process Execution Manager tab page. When you access

the tab page for the first time, the PEM plan is created.

In the screenshot below, you see the Plan view. You can change to another view, the Configuration

View, which is described in detail later.

Figure 1: PEM Plan View

Check if there are dialog activities to be executed by looking for the Execute Dialog Block

pushbutton. If there are no dialog activities to be executed, the pushbutton does not appear. Choose

the pushbutton. A window appears with the dialog blocks you have to process. Click the dialog block

(underlined text) you want to process.


October 2012

Figure 2: PEM Dialog Block

A new window appears where you can see all activities belonging to the dialog block.

Figure 3: View all Activities of a Dialog Block

You are not required to execute optional activities. An activity is executable if it is selected under the

column Act.

Execute the dialog block.

To begin the execution, you need to provide the inputs using dialog blocks. The Execute Dialog Block

pushbutton display all activities requiring input from users.


October 2012

4

After you process all the required dialog activities, the Execute Dialog Blocks pushbutton is not visible

until new required dialog activities are available for processing.

Scheduling Execution

You can set parameters for the plan and the blocks. With these parameters you can define start and re-start options. You can organize when the Plan should be executed. With the re-start options you can determine that restart does not happen after failures. You can also determine how many times after failures should the restart be possible. The value 0 indicates that there are no restrictions in the number of executions and the activity can restart infinite times in case of failure in execution.

Figure 4: Scheduling Process Execution

Start the plan execution by choosing the Start Execution pushbutton.

An information box appears with information that the execution has started. Confirm this message by

choosing OK.

Figure 5: Information Dialog Box

Execution is controled by the batch job CNV_MBT_RUN_PLAN_<your_package_id> in the control

system.

The Start Execution pushbutton is no longer visible. Instead, you can view the Stop Execution


October 2012

5

pushbutton. You can choose this pushbutton to stop the execution of new activities. Activities that are

already running are not stopped.

Figure 6: View the Stop Execution Pushbutton

When you choose the Stop Execution pushbutton, the batch job with the Plan execution is finished

and the Start Execution pushbutton is available again .

In the Plan view for Group 1 Package Settings 02, you can see that the status icon changes to a van

symbol, the status text to Running and the process indicator to 7 %. For the latest information, you can

occasionally choose the Refresh pushbutton.

Figure 7: Check the status of the Blocks


October 2012

6

When you choose the Switch to Configuration View pushbutton, you get the same information as in

the Plan view but in a table format.

Figure 8: PEM Configuration View

If you want to see the activities of the Block Package Settings 02 you can click the text Package

Settings 02 in the Block. This is available in both views.

Figure 9: Activities of Package Settings 02 Block

You see all activities assigned to that block with the same information as in the process tree/process

structure.

The following screenshot shows a cutout of the Plan view during the plan execution. You can see that

in Group 5 the Dialog Block (icon with the little person in upper left corner of the Block) is successfully

(green state and 100 %) executed.

You also see that the batch block is running with a processing of 8 %, while the dialog blocks in Group

6 and Group 7 are already processed to 100 %.

If a dialog block only contains optional activities, the activities are not relevant for the calculation of the

progress and completion is displayed as 100 % and successfully finished. From this information you

can understand that the next set of dialog activities that you have to process comes after finishing the

Block Data Transfer 09 at the earliest. Because the completion is 0 % and this shows that this Dialog


October 2012

7

Block contains required activities.

Figure 10: Status and Activity Completion Percentage of PEM Plan View Dialog Block

If the Processing Gets Stuck

The Plan execution could be running but without any progress.

Reasons

You may have to execute the required dialog activities. Some activities may have terminated.

The Plan execution tries to restart the terminated activities if your activity settings allow this.

If at least one activity is terminated, you can see the Aborted icon in the batch block.

Figure 11: View of a Terminated Activity

Click the underlined block name. You can view a table with all related activities. You can enable more


October 2012

details by selecting the different options in the pull-down menus Activity Display and Columns.

Figure 12: Status of the Terminated Activity

After you locate the aborted activity in the table, you can see that the PEM execution tried to restart

the activity 85 times without success. It would be the best to Stop the Plan execution and fix the

problem. To locate the issue, follow the same steps as from the process tree (check log, check batch

job (aborted, log), check SM21, check ST22, …).

3.2 PEM Plan calculation

Optional activities are registered in the PEM content table as inactive. Inactive activities are not

executed with the PEM plan execution. Activities that are not executable are not written into the PEM

content table.

3.2.1 PEM Plan Recalculation

If after the first calculation something changes in the PCL process tree, a re-calculation of the PEM

plan is required. PEM carries out the recalculation automatically.

If something changes that requires a recalculation, but the PCL process tree is not changed (for

example, imported corrections from a note), you can recalculate the PEM plan by calling the

transaction CNV_MBT_PEP_REPAIR.

3.2.2 PEM Plan Manual Settings

In the SAP LT Workcenter in the PEM area, you can change the Block settings to your requirements.

You can split/merge blocks of the same group and you can set an optional activity to active (so that it

is executed by PEM).

3.2.3 Split/Merge

Split a Block

Split a block into two blocks. We want to move a selection of activities from the Block Data Transfer 09

into a new block. The reason could be that we want to schedule these activities differently than the

other block. Choose the Edit pushbutton in the overview mode.

The Merge Blocks and Split Blocks pushbuttons are visible on the screen after the Edit pushbutton is

selected.


October 2012

9

Figure 13: View Merge Blocks and Split Blocks Pushbutton

We want to split the Block Data Transfer 09, hence we select this row in the table and choose the Split

Block pushbutton.

Figure 14: Choose the Row for Split Block

A screen appears with the activities of the block displayed in the left table (source block). The activities

we want in the new block have to be moved from left to right to the Split Block table. To do this, select

the activity and move it to the right by choosing the Add pushbutton.


October 2012

10

Figure 15: Select Activities to be moved to the New Block

In the screenshot below, the last five activities are selected as an example. Choose Add.

Figure 16: Choose Add Pushbutton to move the Activities to the New Block

To confirm the new Block, save your selections by choosing the Save pushbutton at the bottom right.


October 2012

11

Figure 17: View Activities moved in the New Block

We have now derived two blocks from the original one. This is recognizable by the sequence number

in the Block name.

Figure 18: New Blocks Data Transfer 09-1 and 09-2 are Created

3.2.4 Set Optional Activity as Active

The PEM Plan execution only executes active activities. If you want activities that are not active to be

executed, you can set them as active in the overview of all activities in a block. This overview screen

appears if you are on the Process Execution Manager tab page in the Plan view or Configuration view

and if you click the package name (represented as link).


October 2012

12

Figure 19: View the Opt. and Act. Activities

You see that the last activity - Refresh of Data Deletion Cluster for the Current Transfer

(PC002_DTL_CLUSTER_DELETE_SND) - is optional and not active. This activity is not executed by

PEM. To select the checkbox, choose the Edit pushbutton.

Select the checkbox in the column ‘Act.’

Figure 20: Select the Opt. Activity as Act. Activity

Save your settings to make them valid. The activity is automatically executed by PEM.

Merge Blocks

You can merge blocks in the same group. We use our previous example and merge the splitted block

again. To do this, we have to select the rows with the two blocks.


October 2012

13

Figure 21: Select Two Activities to be Merged

Next, choose the Merge Blocks pushbutton to make one block out of two. A dialog box appears where

you can confirm that you want to merge the two blocks. Choose Yes.

Figure 22: Choose Yes to Merge the Activity

The result is that both blocks are merged into the Block Data Transfer 09-1+09-2.

Figure 23: Blocks Data Transfer 09-1+09-2 are Merged
