Using the output from a rule as input to the expression for other rule

[naheedmk]

Is it possible to use the output of Rule1 as input to the next Rule ? Looking for something below. Accessing "Expression": "context.TotalAmount >= 100000", . The TotalAmount is conditionally calculated in the previous rule, and it needs to be passed to the next Rule.

{
"WorkflowName": "EvaluateRuleActionTest",
"GlobalParams": [
{
"Name": "OrderCount",
"Expression": "1 + 1"
}
],
"Rules": [
{
"RuleName": "TotalAmount5W",
"Expression": "input1 + input2 >= 50000", // Expression to evaluate
"Actions": {
"OnSuccess": [
{
"Name": "OutputExpression", // Action to output TotalAmount
"Context": {
"TotalAmount": "input1 + input2" // Setting TotalAmount conditionally
}
}
]
}
},
{
"RuleName": "TotalAmount10W",
"Expression": "context.TotalAmount >= 100000", // Accessing the TotalAmount from context
"Actions": {
"OnSuccess": [
{
"Name": "EvaluateRule",
"Context": {
"workflowName": "EvaluateRuleActionTest",
"ruleName": "TotalAmount10W"
}
}
]
}
}
]
}

naheedmk,
Please look into below example to work with chained rules

[
  {
    "WorkflowName": "EvaluateRuleActionTest",
    "Rules": [
      {
        "RuleName": "TotalAmount5W",
        "Expression": "input1 + input2 >= 50000",
        "ErrorMessage": "The game doesn't meet the criteria for 5% discount",
        "ErrorType": "Error",
        "Actions": {
          "OnSuccess": {
            "Name": "EvaluateRule",
            "Context": {
              "workflowName": "EvaluateRuleActionTest",
              "ruleName": "TotalAmount10W",
              "additionalInputs": [
                { "Name": "TotalAmount", "Expression": "input1 + input2" }
              ]
            }
          }
        }
      },
      {
        "RuleName": "TotalAmount10W",
        "Expression": "TotalAmount >= 100000",
        "Actions": {
          "OnSuccess": {
            "Name": "OutputExpression",
            "Context": {
              "Expression": "TotalAmount * 0.10"
            }
          }
        }
      }
    ]
  }
]
