How to migrate Tax lines in Data Migration for Partial Shipped Qty?

Question

Hi,
We are migrating 11.0.3 Orders to R12 and there are some Sales Orders which are in Partial Shipped status. In this scenario, we are bringing two lines where one line is completely closed and other line is awaiting shipment.
My question is, how to manage the Taxation for this type of lines?
For e.g. If original line is of 10 qty, 4 qty is already shipped. So we are bringing this line as Closed. For 6 qty, we are bringing line in Awaiting Shipment status. How to derive at the correct tax amount for this type of line?
Client is storing Tax amount in 11.0.3 at Header level.
With Regards,
Vishal

Through the TopLink code API, you can set an
Expression as the additionalJoinExpresssion for a
descriptor, this "filter" will be applied to all
queries for this class.
i.e.
ExpressionBuilder builder = new ExpressionBuilder();
descriptor.getQueryManager().setAdditionalJoinExpressi
on(builder.get("region").equal("AU"));The problem with this solution is that the parameter ("AU") is hard-coded in the mappings. Hibernate filters can use session-specific parameters. That allows, for instance, session A to filter on region="AU" and session B to filter on region="NZ".
To resolve this problem, I wrote a new expression class that can retrieve a parameter value from a TopLink session property:
class SessionPropertyExpression extends ParameterExpression {
public SessionPropertyExpression(String propertyName, Expression base) {
super(propertyName, base);
public Object getValue(DatabaseRow databaserow,
oracle.toplink.publicinterface.Session session) {
return session.getProperties().get(getField().getName());
The new expression class can be used in the mappings. For instance:
ExpressionBuilder builder = new ExpressionBuilder();
SessionPropertyExpression propertyExpr = new SessionPropertyExpression
("regionCode", builder);
descriptor.getQueryManager().setAdditionalJoinExpression(builder.get("region").equal(propertyExpr );
The application can set the property in the TopLink session associated with a particular request. For instance;
Session A
session.setProperty("regionCode", "AU");
Session B
session.setProperty("regionCode", "NZ");
