Workflow Important Debug Queries



deq_time is not always populated in WF_DEFERRED. The best way to monitor is to check if there are any READY events
select msg_state,count(*) from applsys.aq$wf_deferred  group by msg_state;


For getting Item_Type and Display name for Runnable processes.
SELECT WFA_ACT.ITEM_TYPE ITEM_TYPE ,
  WFA_ACT.NAME PROCESS_NAME ,
  WFA_ACT.DISPLAY_NAME DISPLAY_NAME
FROM wf_activities_vl wfa_act
WHERE wfa_act.runnable_flag = 'Y'
AND wfa_act. type            = 'PROCESS'
AND sysdate BETWEEN wfa_act.begin_date
AND NVL(wfa_act.end_date, sysdate);


Query to find records that are pending in each of the workflow agent listener queues
SELECT 'select ''' || t.component_name || ' (queue_table: ' || p.queue_table ||
       ')''||'' Count: ''||count(*) c from ' || p.owner || '.' || .queue_table ||
       ' where deq_time is null and nvl(delay,enq_time)<sysdate-1/24  ||
       nvl2(t.correlation_id,
            'and corrid like ''' || t.correlation_id || ''' ',
           NULL) || 'having count(*)>0;'
  FROM applsys.fnd_svc_components t,
       applsys.wf_agents          o,
       dba_queues                 p
 WHERE t.inbound_agent_name || t.outbound_agent_name = o.name
   AND p.owner || '.' || p.name = o.queue_name
   AND t.component_type LIKE 'WF_%AGENT%';
 
Query helps to determine which activities are in the WF_DEFERRED_TABLE_M
select w.user_data.itemtype "Item Type", w.user_data.itemkey "Item Key",
decode(w.state, 0, '0 = Ready',
1, '1 = Delayed',
2, '2 = Retained',
3, '3 = Exception',
to_char(w.state)) State,
w.priority, w.ENQ_TIME, w.DEQ_TIME, w.msgid
from wf_deferred_table_m w
where w.user_data.itemtype = '&item_type';
 
Check the various workflow agent listeners and their statuses
SELECT t.component_name,
       p.owner,
       p.queue_table,
       t.correlation_id
  FROM applsys.fnd_svc_components t,
       applsys.wf_agents          o,
       dba_queues                 p
 WHERE t.inbound_agent_name || t.outbound_agent_name = o.name
   AND p.owner || '.' || p.name = o.queue_name
   AND t.component_type LIKE 'WF_%AGENT%'; 


Select all workflow items for a given item type
SELECT item_type,
       item_key,
       to_char(begin_date,
               'DD-MON-RR HH24:MI:SS') begin_date,

       root_activity activity
  FROM apps.wf_items
 WHERE item_type = '&item_type'
   AND end_date IS NULL
 ORDER BY to_date(begin_date,
                  'DD-MON-YYYY hh24:mi:ss') DESC;

        wn.context,

        wn.status,
        wn.mail_status,
        wn.message_type,

The following query will show workflows with high volumes of looping activity. If that is the case, it is required to change the workflow which is causing the looping. The workflow has to be changed as soon as possible otherwise it can generate several rows in the WF tables.

Activities are not Processed by Workflow Background Engine
Activities are in READY status in WF_DEFERRED_TABLE_M queue even though the Workflow Background engine program was already executed.
First review if the aq_tm_processes parameter which needs to be higher than zero to dequeue the messages from WF_DEFERRED_TABLE_M queue.
How to check the current value of aq_tm_processes?
SELECT value
FROM v$parameter
WHERE name = 'aq_tm_processes';
If this value is equal to zero, please contact the DBA to change it to 1 or higher.
If aq_tm_processes parameter is different than zero and the messags are still not dequeued from WF_DEFERRED_TABLE_M queue then the recommendation is to re-create this queue as follows:
a. Stop the Workflow background engine programs in running status
b. Recreate the wf_deferred_table_m queue by executing:
sqlplus wf_account/wf_account @$FND_TOP/sql/wfbkgbld wf_schema
Example Syntax:
sqlplus apps/apps @$FND_TOP/sql/wfbkgbld applsys
c. Execute the wf background engine program again
d. Retest the issue.
Note.1176723.1  also contains the step by step instructions to recreate the WF_DEFERRED_TABLE_M queue.

How to setup and use AME - Approval Management Engine

Approval Management Engine - AME For Purchase Requisition Approvals Purchase Requisitions can be routed for approval using the AME Approval Management Engine. This whitepaper describes how to setup AME for use with requisition approvals, and shows how a requisition approval list is built based on the AME setup. Approvers in the AME based approver list are assigned to the requisition based on the AME rules setup for the Purchase Requisition Approval transaction. Similar setup can be done for Requester Change Order Approval and for Internal Requisition Approval, although those are not specifically covered in this whitepaper. The screenshots provided are based on 11i.AME.B, and some of the navigation details are specific to 11i.AME.B. However, most of the details provided are applicable to 11i.AME.A and higher including R12. Assign AME Roles and Responsibilities AME responsibilities in 11i.AME.A are assigned directly to the users. However, In R12 or 11i.AME.B and higher, AME respons

How to compile all INVALID objects in Oracle

There are five ways to recompile invalid objects in schema. DBMS_DDL DBMS_UTILITY UTL_RECOMP UTLRP.SQL Manually Recompile > Best Approach 1. DBMS_DDL This procedure is equivalent to the following SQL statement: ALTER PROCEDUREFUNCTIONPACKAGE [.] COMPILE [BODY] Syntax Exec dbms_ddl.alter_compile ( type , schema, name); Type : Must be either PROCEDURE, FUNCTION, PACKAGE, PACKAGE BODY or TRIGGER. Schema : Database Username Name : Objects name Example SQL> exec dbms_ddl.alter_compile ('PROCEDURE','SCOTT','TEST'); PL/SQL procedure successfully completed. 2. DBMS_UTILITY This procedure compiles all procedures, functions, packages, and triggers in the specified schema. Syntax Exec dbms_utility.compile_schema ( schema,compile all) Schema : Database Username Compile All : Object type ( procedure, function, packages,trigger) Example SQL> exec dbms_utility.compile_schema('SCOTT'); PL/SQL procedure successfully co
