Create Roles:

Adhoc roles can be created through PL/SQL from database or they can be created

from Applications using User Management Responsibility. If you use PL/SQL to create roles make

sure you give all user names and role names in UPPER case to avoid some problems

Script to Create a Adhoc Role

Script to Add user to existing Adhoc Role

Script to Create a Adhoc Role

DECLARE

lv_role varchar2(100) := ERPSCHOOLS_DEMO_ROLE;

lv_role_desc varchar2(100) := ERPSCHOOLS_DEMO_ROLE;

BEGIN

wf_directory.CreateAdHocRole(lv_role,

DECLARE

v_role_name varchar2(100);

v_user_name varchar2(100);

BEGIN

7)Launching workflow from PL/SQL:First create a database trigger as below to call a PL/SQL procedure from which you kick off

the workflow.

Create Database Trigger

CREATE OR REPLACE TRIGGER ERP_SCHOOLS_DEMO_TRIGGER AFTER INSERT ON

INV.MTL_SYSTEM_ITEMS_B REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW

DECLARE

lv_id NUMBER := :NEW.inventory_item_id;

lv_item_segment1 VARCHAR2(100) := :NEW.segment1;

lv_itemtype VARCHAR2(80) := :NEW.item_type;

lv_user_id NUMBER := -1;

lv_itemkey VARCHAR2(10);

lv_orgid NUMBER :=2;

error_msg VARCHAR2(2000);

error_code NUMBER;


38/44

BEGIN

lv_user_id := fnd_global.user_id;

lv_orgid := fnd_global.org_id;

lv_itemkey := 1132; This should be unique value

ERP_DEMO.LAUNCH_WORKFLOW(ERP_DEMO

,lv_itemkey

,ERPSCHOOLS_PROCESSprocess name

,lv_id

,lv_orgid

,lv_item_segment1

);

EXCEPTION

WHEN OTHERS THEN

error_code := SQLCODE;

error_msg := SQLERRM(SQLCODE);

RAISE_APPLICATION_ERROR(-20150,error_msg);

END;

/

Create PL/SQL Package to kickoff workflow

CREATE OR REPLACE PACKAGE APPS.ERP_DEMO IS

PROCEDURE LAUNCH_WORKFLOW

(

itemtype IN VARCHAR2,

itemkey IN VARCHAR2,

process IN VARCHAR2,

item_id IN NUMBER,

org_id IN NUMBER,

item_segment1 IN VARCHAR2

);

END ERP_DEMO;

/

CREATE OR REPLACE PACKAGE BODY APPS.ERP_DEMO IS


40/44

PROCEDURE LAUNCH_WORKFLOW(

itemtype IN VARCHAR2,

itemkey IN VARCHAR2,

process IN VARCHAR2,

item_id IN NUMBER,

org_id IN NUMBER,

item_segment1 IN VARCHAR2

)

IS

v_master_form_link varchar2(5000);

v_item_number varchar2(100);

error_code varchar2(100);

error_msg varchar2(5000);

BEGIN

v_add_item_id := ITEM_ID= || item_id || ;

v_item_number := item_segment1;


41/44

v_master_form_link := v_master_form_link || v_add_item_id;

WF_ENGINE.Threshold := -1;

WF_ENGINE.CREATEPROCESS(itemtype, itemkey, process);

Get the value of attribute assigned in workflow

v_master_form_link := wf_engine.getitemattrtext(

itemtype => itemtype

,itemkey => itemkey

,aname => ERP_SEND_ITEM_FORM_LINK);

- assign values to variables so that you can usethe attributes

v_master_form_link varchar2(5000) := v_master_form_link||:#RESP_KEY=INVENTORY

#APP_SHORT_NAME=INV ORG_MODE=Y ;

v_master_form_link := v_master_form_link || v_add_item_id;

set the attribute values in workflow so that you can use them in notifications

WF_ENGINE.SetItemAttrText(itemtype, itemkey, MASTERFORM, v_master_form_link);

WF_ENGINE.SetItemAttrText(itemtype, itemkey, ERP_ITEM_NUMBER, item_segment1);


42/44


43/44

IS

v_GET_ITEM_NUMBER VARCHAR2(1000);

BEGIN

SELECT SEGMENT1 INTO V_GET_ITEM_NUMBER FROM MTL_SYSTEM_ITEMS_B WHERE

ROWNUM =1;

WF_ENGINE.SetItemAttrText(itemtype, itemkey,

ERP_ITEM_NUMBER,v_GET_ITEM_NUMBER );

you can use the get function as below.

v_GET_ITEM_NUMBER := wf_engine.getitemattrtext(

itemtype => itemtype

,itemkey => itemkey

,aname => X_ATTRIBUTE);

resultout:=COMPLETE:||Y';

exception when others then

dbms_output.put_line(Entered Exception);


44/44

fnd_file.put_line(fnd_file.log,Entered Exception);

END GET_ITEM_DETAILS;

END ERP_DEMO;
