Script Callout

Status

• Testing for Next Release 340 - January, 2008
  
• A real huge contribution from Carlos Ruiz, Quality Systems & Solutions (QSS), Colombia
• Now it can work with any java scripting language such as Groovy and Jython, thanks to Víctor Pérez, E-Evolution (Libero), Mexico

Creating the Rule

Within the script you can use:

• Window context variables start with a W_ prefix
• Login context variables start with G_ prefix
• Parameters for callout start with A_ prefix
  • A_WindowNo
  • A_Tab
  • A_Field
  • A_Value
  • A_OldValue
  • A_Ctx

Configure Callout from Table/Column

• This Callout can also be called from the Report & Process Window. Just remember to set in the Rule window from which Event Type are you calling this Rule Script.

Sample Code provided for copy/paste testing

On the Table and Column, callout reference:

@script:beanshell:BP_fillDescriptionFromName

On the Rule Search Key:

beanshell:BP_fillDescriptionFromName

On the Rule Script:

if (A_Tab.getValue("Name") != null) {
    A_Tab.setValue("Description", A_Tab.getValue("Name"));
}
result = "";

Scripting Languages

• Now standard Adempiere has uploaded jars to work with groovy, jython and beanshell
• to call a script from a Callout follow these sample syntax:
  • @script:beanshell:ValidateQtyOnHand
  • @script:groovy:ValidateQtyOnHand
  • @script:jython:ValidateQtyOnHand

• When you create the rule, you have to set in the Search Key such as:
  • Search Key : beanshell:ValidateQtyOnHand
  • Search Key : groovy:ValidateQtyOnHand
  • Search Key : jython:ValidateQtyOnHand

• Set the Event Type as Callout and Rule Type as JSR 223 Scripting APIs
