Hello all,

We created an integration on ICS that exposes OTBI query data as a JSON File. This query returns the Requisition Number and also the Supplier for a specific item on that requisition. The problem is that some supplier names contain the special character "&" and we noticed that when that happens, the integration returns a parsing error. 

We'd like to know if there's a way to escape the special character.
