Automation for Restriction on Increasing PO Quantity for the PO Revision but Allow the Quantity Decrease || IBM Maximo

Recently we had a requirement of Increasing the PO quantity on the PO revision but allow the quantity increase. So, We used the automation script getPreviousValue() and getCurrentValue() functions in order to resolve this requirement.

Create Database Error Message on Database Config Application.

Object :         POLINE

Attribute:      ORDERQTY

Events:          Validate

Body:

Usage of MboValueAdapter in Maximo Scripts | Maximo

short version to get the PreviousValue which can only be get via the MboValueAdapter
pstatus= mbo.getMboValue("status").getPreviousValue().asString()

Example a script to get previous status and current status to display message.

pstatus= mbo.getMboValue("status").getPreviousValue().asString()
if mbo.getString("status") == 'COMP' and pstatus == 'WASSET':
   if mbo.getInt("item.rotating") ==  1:
       warngroup = "assrecmsg"
       warnkey = "assrecmsg"
