how to create a Global variable in WADE

[WOONGYO Han]

​I would like to create and use a date variable using the Global variable of WADE as shown below.

I would like to know how to create a Global variable to use as below.

1. Date Format : YYYYMMDD
   Global Variable : YDAY :   Yesterday
                               TDAY : Today
2. Date Format : YYYYMM
  Global Variable : PM : the previous month
                             CM :  current month

Hi, 
Below are a 3 examples using 3 different methods.  I prefer the first method. Especially if the variable is only used in the current application.  Let me know if there are any questions. 
NOTE: "less 1 workday" will need to be changed to "less 1 day"
There may be much better ways to make this happen. 

********************************************************************************************************************************

Option 1 - Creating a Application level variable - ********************************************************************************************************************************

In the Event

genTime('DB','today less 1 workday'); 

APPL.year=DBYEAR; 

APPL.month=DBMM; 

APPL.day=DBDD; 

APPL.yy=DBYEAR - 2000;

In the job "Arguments to pass" Below is a sample arg. 

"%APPL.day-%APPL.month-%APPL.yy"

 

********************************************************************************************************************************

Option 2 - Setting an ESP level variable. 

********************************************************************************************************************************

The event JavaScript

genTime('DB','today less 1 workday'); 

APPL.year=DBYEAR; 

APPL.month=DBMM; 

APPL.day=DBDD; 

APPL.yy=DBYEAR - 2000;

ESP.FHLB_DT3 = "%APPL.day-%APPL.month-%APPL.yy";

 

In the job "Arguments to pass" below is a sample arg

 "%ESP.FHLB_DT3"

 

 

********************************************************************************************************************************

Option 3 - Global Variable Table - this will need to be run daily to recalculate the global variable daily

********************************************************************************************************************************

Below is the method using the global variable table. 

In order to set the global variable you would need to issue a set command in the JavaScript. 

Example: Modifying a Global Variable in a JavaScript Script. This would need to be run daily to set the variable. 

The following example modifies the value of a global variable named FHLB_DT2. The FHLB_DT2 variable is assigned a value of the date representing "Today less 1 workday". 

genTime('DB','today less 1 workday'); 

APPL.year=DBYEAR; 

APPL.month=DBMM; 

APPL.day=DBDD; 

APPL.yy=DBYEAR - 2000;

setVar('FHLB_DT2','%APPL.day-%APPL.month-%APPL.yy');

Example: Retieving the Global Variable in a JavaScript Script

JavaScript in the job will need to be used to retrieve the variable.   

ESP.date2 = getVar('FHLB_DT2');

 

In the job…Below is a sample arg..

"%ESP.date2"
