Question about Ruleset processing, FIND's not in Context?

gerber1

I am missing some aspect of Ruleset processing. I am probably doing something wrong. Anyway, here goes.

I have object OrderDetail, and below is the Ruleset for create/modify for it. The objective is to setup some of the key values once a user selects the product for the new line. In other words, they click "Add New" and see a blank line with a combo box from which to choose the Product.

I am not getting what I expect. The fundamental undesired behavior I see is that it fails to recognize the objects from the FIND requests, which I know were successful. The attrbute assignments from the FIND results do not occur, and any values tested in IF statements are not resolved, so it skips the THEN part. I pasted exerpts from the Aware IM Server log below to show this. I have the whole sequence and will provide it if needed. It is a few pages long...

...Executing action FIND Person WHERE Person=OrderDetail.OrderCustomer.Person from rules of object OrderDetail
2011-07-26 17:47:20,336 L3WBCHEM01#Roy -33 Found 1 objects
...Executing action FIND Person WHERE Person=OrderDetail.OrderCustomer.Person from rules of object OrderDetail
2011-07-26 17:47:20,336 L3WBCHEM01#Roy -33 Found 1 objects
...Executing action FIND Discount WHERE OrderDetail.OrderCustomer.Person.PersonCategory IN Discount.PersonCategories AND OrderDetail.Product.ProductCategory IN Discount.ProductCategories TAKE BEST 1 from rules of object OrderDetail
2011-07-26 17:47:20,341 L3WBCHEM01#Roy -33 Found 1 objects

The engine executes each of these twice with the same outcome (found).

The activity I describe here was initiated using the "Add New" button from a form where OrderDetails, a collection of OrderDetail objects belonging to

OrderCustomer.
NOTE: This is not a Process. Input objects is not the problem here.

Ruleset:

Name/Rule
FindPerson -- FIND Person WHERE Person=OrderDetail.OrderCustomer.Person
AssignProductValues -- FIND Product WHERE Product=OrderDetail.Product
AssignTaxable -- OrderDetail.Taxable=Product.Taxable
AssignProductType -- OrderDetail.Type=Product.Type
FindDiscount -- FIND Discount WHERE (OrderDetail.OrderCustomer.Person.PersonCategory IN Discount.PersonCategories AND OrderDetail.Product.ProductCategory IN Discount.ProductCategories) TAKE BEST 1
DeterminePctDiscount -- IF Discount.DiscountType='%' THEN OrderDetail.DiscountAmt=ROUND(Product.Price * 0.01*Discount.DiscountAmt,2)
DetermienDolDiscount -- IF Discount.DiscountType='$' THEN OrderDetail.DiscountAmt=Discount.DiscountAmt
AssignPrice -- OrderDetail.Price=OrderDetail.Product.Price-OrderDetail.DiscountAmt
CalculateExtension -- OrderDetail.ExtPrice=OrderDetail.Quantity * OrderDetail.Price

Clearly the Configuration Tool is anticipating the following complaints when I go to save the Ruleset...
Possibly wrong object identifier Product is used in path Product.Type in rule AssignProductType
Possibly wrong object identifier Discount is used in path Discount.DiscountAmt in rule DetermienDolDiscount
Possibly wrong object identifier Product is used in path Product.Taxable in rule AssignProductTaxable
Possibly wrong object identifier Discount is used in path Discount.DiscountType in rule DetermienDolDiscount
Possibly wrong object identifier Discount is used in path Discount.DiscountAmt in rule DeterminePctDiscount
Possibly wrong object identifier Discount is used in path Discount.DiscountType in rule DeterminePctDiscount
Possibly wrong object identifier Product is used in path Product.Price in rule DeterminePctDiscount

Of course, it looked OK to me, so I saved and ran it.

The engine seemed to scramble a bit processing this, repeating the FINDs many times, so I added Priority to make sure FIND's were completed before it started evaluating the other attributes. That seemed to shorten the execution path, but it did not resolve my problem.

Any help is welcome!

Do not ignore the "Possibly wrong identifier" warning - in most cases this is an indication that the object you are using is not in the context, which is almost always a problem.

Please read the context in the User Guide and make sure you understand it. Product and Discount objects must be in the context. If your rules are attached to some object, the Product and Discount objects must be referenced from that object, for example, MyObject.Product

Thanks. Found it on p. 62 in Note 3, and my issue is resolved...

When rules of an un-ordered rule collection are executed (see Evaluation of Unordered Rule Collection) instances of business objects and notifications created by the CREATE or ENTER NEW actions or found by the FIND or PICK FROM actions are not written into the Context of the un-ordered rule collection. Instead these instances are made available only within the action block that contains the FIND (PICK FROM) or CREATE (ENTER NEW) actions.

So, the key is to contain my activities in the action blocks containing the FIND's instead of breaking them out. I gues alternatively, I could call a Process, where FIND's, etc. DO go into that context.

Thanks again,
