Rule Help

Hi all,
I was wondering if someone could help me write a rule. This one has stumped me. I am entering records in a business object. Each one has an incrementing document number and a revision number which is a separate atribute which defaults to 0 when a new record is created. When there is only one occurrance of the document the number is 0 when there are 2 occurrances the revision number then incrments. To complicate the issue there is a status attribute as well this shows active/archived depending on how many occurrances of each document there are. If there is only one occurance of the document number then the status is active if there are more than one occurance then all preceding revisions (all revision numbers less than the highest one) must show archived satus.

Is there someone who can help me write this rule? It may need a couple of rules. I am just not sure how to tackle it.

All help appreciated.

I assume you have a BO Document and a daughter BO Revision and it is 1 to N relationship. Document has an attribute Revisions of revision type and Revision has a matching attribute MyDocument, RevisionNo and Status with initial value Active. Then you can try this approach. Note however that you need to check syntax of code lines below as I am typing from memory

Add attribute CurrentRevision to Document and this rule to define it

If (Document.Revisions IS DEFINED AND Document IS NEW) OR (NOT(Document IS NEW) AND Document.Revisions WAS CHANGED) Then
Document.CurrentRevision=COUNT Revision WHERE (Revision IN Document.Revisions) -1

Add this rule to Revision

If Revision IS NEW Then Revision.RevisionNo=Revision.MyDocument.CurrrentRevision+1

And this one to Document

If Revision WAS ADDED TO Document.Revisions Then
ChangeStatus

where ChangeStatus is a process with input Document:

FIND Revision WHERE Revision IN Document.Revisions AND Revision.RevisionNo=Document.CurrentRevision-1

Revision.Status=Archived
