Error while updating Replenishment order

Hi All,

I am trying to update the replenishment order details at Item Level. For that i am using the class CL_ODM=>Set2 it gives an error message "Mapping Information for the ID delivered is missing".

While i am using the Get method, i will get the Header details, item details and Exten details but i will not get any data in mapping table.

Please provide any other process / method to update the replenishment order.

Thanks in advance.
