Avoiding Logical Loop Error while defaulting values

Question

Hi Experts,
We have a requirement where lets say Attribute A and Attribute B are displayed on the screen, we need to default value for Attribute B to NA if value of Attribute A is set by the user to "XYZ", else whatever value user enters in Attribute B will be set. To achieve this, we are setting the value of the Attribute B in the rule document. If we use the validation rule table like mentioned below, it throws a logical loop error:
Attribute A
“NA”
Attribute B = "XYZ"
Attribute A
otherwise
To avoid this, we are using a dummy attribute for Attribute A (which is not displayed on the screen) to set in the rule document as mentioned below and this attribute will be shown in the decision report:
Attribute A Dummy
“NA”
Attribute B = "XYZ"
Attribute A
otherwise
The issue is, we are sending the Session data to Siebel through OPA connectors. Now these dummy attributes as mentioned above (which are not displayed on UI) are not sent as part of the Session data as these are inferred attributes.
Is there any way to:
1. Solve the logical loop error issue so that we dont have to use the dummy attribute
2. If we have to use dummy attributes, then how to send them to Siebel as part of session data.
