How can we transfer the header fiedl value to the item

Question

we have add the "storage location" field to the sales order head and item, now we need to batch change the item's storage location when we change the head's storage fields ,
we have use the function module in 'crmc_map' transcation, but with some problems,  when we change the head's field, we can't triger the item's 'SET' event, so we can't change's the item's fields(through the screen is changed, but when we use 'CRM_ORDERADM_I_READ_OW'  to get the value, it stand still);
we also tried to when we change the head's field,  we use head's set event to change to item's value, but we can't get item's guid, so Now I have no idea to deal with it.
Any body can help me?
Thanks a lot!

Hi,
     Using the set method in this scenario is not reliable. The set methods are triggered only for displayed items, whereas you need to change the value for, I presume, all the items. In the code where you change the header field value, write the code to change values for items as well. The approach will differ depending on whether you are using the BOL method or directly call the maintain APIs.
