Overview :
SAP provides a standard mechanism to track changes to fields using Change documents and the same concept is used
track changes to the Project object fields . Fields with their data element activated for Change documents are captured
as Change Documents ( Stored in DB table CDHDR and CDHDPOS).
Further , SAP provides an Out of the box mechanism to trigger workflow on changes made to any field in PPM with some quick steps
discussed below
Use Case
Trigger workflow On Change to any Field value in the Project in SAP PPM
Prerequisites:
Ensure the Change Doc Object to be configured is existing in tcode SCDO
Steps Required
Step 1 : Activate change docs for the object DPR_DPO (For Projects) in SPRO path
Portfolio Management
Global Customizing
Process and Service Settings
Activate Change Document
Note : To see the change docs tab for Project in SAP PPM , ensure the tab is not hidden in User settings in project application in Web UI.
Step 2 : Go to tcode SWED to configure at what actions you want to store/generate change docs for the object
chg Doc Object |Leading Object table|Chg Doc Key with Struct
| DPR_PROJECT | DPR_PROJECT | DPR_PROJECT |
Select Action(change) , create or delete of change docs as required
Strcuture | Function Module
| DPR_TS_BUSINESS_OBJECT_KEY | BAPI_BUS2175_OBJECT_KEY_SET |
Step 3:
Create Workflow BO Object(SWo1) / Class(SE24) and the Workflow Template (SWDD) for the workflow to be triggered
with start event as one defined in BO object/class
Step 4 :
Go To Tcode SWEC and Configure the event for the BO Object/Class created in Step 4 above on required action i.e.
Create / Change / Delete of Change docs
OR you can specify the conditions in the Condition editor
Troubleshooting tips
Once all the steps are done , and the workflow is still not triggered , below are some steps to check :
- Ensure event linkage is maintained in tcode SWE2
- Switch on the event trace in tcode SWELS and check if event is traced in tcode SWEL
