How to troubleshoot: Getting duplicate values causing conflict error

[Digvijay]

Hello Splunk Experts ,

I have following dashboard 

I want to filter dropdown "Select Operation" on basis of API and Method dropdown selection ,but I am getting 'duplicate values causing conflict' error.

Below is my code :

<input type="dropdown" token="token_service" searchWhenChanged="true">
<label>Select API:</label>
<choice value="party_interaction_rest">PARTY INTERACTION</choice>
<choice value="ticket_mgmt_rest">TICKET MANAGEMENT</choice>
<choice value="customer_management_rest">CUSTOMER MANAGEMENT</choice>
<choice value="agreement_management_rest">AGREEMENT MANAGEMENT</choice>
<choice value="product_order_rest">PRODUCT ORDER</choice>
<choice value="cust_comm_rest">CUSTOMER COMMUNICATION</choice>
<choice value="product_inv_rest">PRODUCT INVENTORY</choice>
<change>
<condition label="PARTY INTERACTION">

Is there a reason why you have used the below condition check for the "METHOD Dropdown"?

<change>
<condition value="Alle">
<set token="token_method">*</set>
</condition>
</change>

If you just need to have the token of METHOD to be passed to "Operation" dropdown , delete the above piece of code as you dont need to have it. Once done you should be able to see the results as expected.

ISSUE

As you are using * as the token output for Method=Alle, you are seeing multiple values for 'Operation' dropdown. Removing the above piece of code should help in resolving it.
