  2. Deferred Workflow Context Issues • Issue Summary • Oracle Database Session Context • Item Type Selector • Order Management Example

  3. Issue Summary This presentation is follow up on an Oracle E-Business Suite Workflow issue reported by several WF SIG members at the last WF SIG meeting at Oracle OpenWorld. Oracle Workflows were reported to: • Not updating records with the correct Row Who data • Some customizations don’t seem to have the Operating Unit (ORG_ID) set properly

  4. Oracle Database Session Context There are two primary groups of data: • Row Who Data Set using: FND_GLOBAL.Apps_Initialize(l_user_id, l_resp_id, l_resp_appl_id); • Operating Unit (ORG_ID)Set using:FND_CLIENT_INFO.Set_Org_Context(to_char(l_org_id));

  5. How is Database Session Info Set If the workflow is running in real time (non-deferred mode) then the database session info is inherited from the users database session. The workflow is running in this users database session.

  6. Deferred Workflows DB Session • Deferred workflows are run by the Workflow Background Process. • The Workflow Background Processes run many different Item Type Processes for many different users and operating units. • So how is this suppose to work….

  7. Item Type Selector On the Item Type Properties form there is a field for Selector.

  8. Workflow Development Guide Developer’s Guide, Release 2.6.3,Part No. B10284–02 Page 3-5, Item Type Selector Function Used to: • Auto select the runnable process for a given Item Type • As a Call Back function to set database session context for deferred activities • Page 6-13, Standard API for an Item Type Selector or Callback Function

  9. How does this work Oracle Workflow calls the selector/callback function with the following commands: • RUN: to select the appropriate process to start • TEST_CTX: to determine if the current item type context information is correct before executing a function • SET_CTX: to establish any context information for an item type and item key combination that a function activity in the item type needs in order to execute. Automatically during switches in Item Type/Item Key.

  10. RUN • This mode returns the Item Type’s process name to be run

  11. TEST_CTX • The Selector Function is first called in this mode. • It is the developers responsibility to determine if the database session info is set correctly • If the database session is set correctly return TRUE • If the database session is not set correctly return FALSE • The call Selector Function in SET_CTX mode

  12. SET_CTX • It is the developers responsibility to correctly set the database session information. • The ideal situation is to store session context information in Workflow Attributes. • Some modules derive the session context from the source document, (ie. Order Header, Requisition Header, etc.). • Again it is up to the development team to decide how/when to do this

  13. Order Management The selector functions are:Header = OE_STANDARD_WF.OEOH_SELECTORLine = OE_STANDARD_WF.OEOL_SELECTOR Within these functions there are if statements which will avoid setting the database session unless the PL/SQL global variable, OE_STANDARD_WF.G_RESET_APPS_CONTEXT is set to true.

  14. Order Management (cont) The selector functions are:Header = OE_STANDARD_WF.OEOH_SELECTORLine = OE_STANDARD_WF.OEOL_SELECTOR Within these functions there are if statements which will avoid setting the database session unless the PL/SQL global variable, OE_STANDARD_WF.G_RESET_APPS_CONTEXT is set to true.

  15. Order Management (cont) I have not found exactly how this global variable is being set. However, Oracle Support did say that the Row Who data will not be correct unless the Workflow Background Process is run individually for each of the OM Item Types: OEOH & OEOL That is impractical at most sites since the there are 50-100 active Item Types, each would require their own Workflow Background Process.

  16. Order Management (cont) • ER 5303011workflow background process not setting last_updated_by to correct user • ER 4060422request workflow background process can be run with category ranges

  17. Order Management Summary • In summary, don’t rely on the database context information being set properly on deferred OM Workflow Processes • This translates into inaccurate Row Who data in OM • Warn your auditors that this is a known Oracle E-Business Suite deficiency
