I have two feature: first where I have arguments and second where I want to send argumnets from first feature.

First feature:

Feature: test
@dev
  Scenario: test

    * def arguments = { value: '123.00', jspath: '..transferData.amount',consent_body: 'classpath:consent_domestic.json' }
    * def createConsentResult = call read('classpath:reuseable/features/changeConsentBody.feature') arguments

Second feature:

@ignore
Feature: Change consent body - 1 parameter

  Background:
    * url ''
    * call read('classpath:reuseable/features/commonFunction.feature')

  @act
  Scenario : Change consent body - 1 parameter

    * path 'consents'
    * def consentBody = read(consent_body)
    * print "jsonPath: "+jspath
    * set consentBody jspath= value
    When request consentBody
    And method post
    Then status 201

Here * def consentBody = read(consent_body) karate sees 'consent_body' as a variable and uses value of this variable.

Here * print "jsonPath: "+jspath karate sees 'jspath' as a variable and uses value of this variable and print: [print] jsonPath: ..transferData.amount.

BUT here * set consentBody jspath = value karate doesn't see 'jspath' as a variable and doesn't use the value of this variable. Instead , karate shows error:

changeConsentBody.feature:17 - unexpected path: jspath

In this case karate need to see 'jspath' as a variable and use the value of this variable.

Sorry your question has to be simplified if you really want people to have the patience to go through and understand the problem. Please refer to this in future: https://stackoverflow.com/help/mcve

That said, I see two obvious problems here. By the way, please maintain white-space on each side of the = sign:

* set consentBody jspath = value

Variables will not work for the set command. And you cannot use JsonPath. If you have dynamic paths, you can do this, refer: https://github.com/intuit/karate#eval

* def foo = {}
* def path = 'bar'
* eval foo[path] = 'baz'
* match foo == { bar: 'baz' }

If you want to update an array in "bulk", instead of ..transferData.amount - please use the karate.map() operation: 

* def foo = [{},{}]
* def fun = function(x){ x.transferData = { amount: 100 }; return x }
* def res = karate.map(foo, fun)
* match res == [{ transferData: { amount: 100 } }, { transferData: { amount: 100 } }]

Finally I urge you to read this carefully, try to avoid "generic" test cases and using call, it just complicates things un-necessarily: https://stackoverflow.com/a/54126724/143475

    one more way would be to use the embedded expression in your `consent_domestic.json`, you can add `'#(value)'` as a value for all the `amount` you want to modify. something like this `{ transferData: { amount: '#(value)'} }`. – Babu Sekaran Feb 20 '19 at 13:44
  • If _'Variables will not work for the set command.'_, then why for 'consentBody' and 'value' it is working? For two of three params it is working and I think it will be logical if it will be working for the third too. – cheparsky Feb 20 '19 at 14:22
  • @cheparsky `set` is useful for 90% of the folks who write simple test cases without trying to be too "generic". if you feel that it is not right, assume that the `set` keyword does not exist and stick to using `eval`. – Peter Thomas Feb 20 '19 at 15:06
