In Build Code, Joule throws error message exceeded the AI usage

[SrihariC]

Hello All,

While trying to generate Entity and Services using Joule, I have keyed the below text:

"Create Entity :MyCars" and services "MyCars" based on the below fields with type string: ConditionType, PostalCode,E ntitlementGroup, ConditionRecord, VAKEY_LONG, S4TableName, S4TablePrefix, CustomerID, ProductClass, SalesOrg, Division, Channel, Plant, ShippingPoint, DestinationZone, SatelliteLocation, Incoterms, Incoterms2, Amount, Unit, UoM, ValidFrom, ValidTo, ValidFromDate, ValidToDate, WillCallRate, DateTimeReceived, IsValidRecord, ScaleQuantity, Per, ScaleLineNumber, ScaleAmount, ScaleIndicator, PriceSegment"

I receive the error message: Cannot generate the requested code as you have exceeded the AI usage.

What is the span of this usage and how many times it can be used? 

Thanks

Srihari
