Speedriser, You would have to create it yourself, it is not available out of the box.

Thanks for the tip. I think it makes more sense to use the "aggregate" action. Can you point me to the right documentation that provides more details on the functionality of "aggregate" action. I dont find details of it in the programmer guide.

Hi, You would have different options:

either you write your query in SQL and use the ApplySQL SOAP action

you define a specific method "aggregation" which will look for an "aggregate_mode" attribute
In this method you will run a get query based on the provided information
And you will aggregate the result in c# based on the aggregate_mode you selected.
Then you just have to call your method in AML:

<Item action="aggregate" type="part" aggregate_mode="max" aggregate_criteria="cost"> <make_buy>1</make_buy> </Item> It's just an idea
