Question

Hi, I am new to Appian and I'm having the following error when building my application. 
 I'm trying to configure the rule inputs but the message "Invalid index: Cannot index property 'relationships' of type Text into Type RecordType. 
 I'll attach a screencapture. 
 Thank you in advance for your help.

Hi Martin Rodriguez couple of questions from my side 
 
 Where are you doing this in the interface Rule inputs? If yes, then you are mapping it in the wrong way. The field you use to save the value must be configured in its value and saveInto fields with recordType!yourrecord.relationship.relatedrecord.fields.fieldValue. 
 Did you establish mapping between the parent record and the child record?

Here my rule input is of any type. Since your input type is W0112SA Vehicle, you will pass a variable which hold the data of type W0112SA Vehicle. The below is a screenshot of how I passed the value. 
 
 I have used a local variable here, in your case you can use a rule input in the parent interface which might hold the data or call an expression which queries your data.
