BT Order item Pricing Conditions (BTItemConditionSet) - how to build correct relationship?

Hi there –

I have a requirement to copy an order item to a sub-item,based on certain conditions. (in EH_ONCOPY)

Everything is working fine for the copy (material, qty etc.), except for the item pricing conditions – one manual item condition is not being copied over, and so the screen field CONDITIONAMOUNT1 is not updated. (this is a user input value on original line, that I want to copy to the new line when they hit ‘Copy’)

I have tried various approaches , using the relationships BTItemConditionSet, and BTCondICondLineAll but with no success. I also tried
to use BTCondICondLineEasyEntry1 but again, could not get it to work

I am using code such as this, to iterate through the original condition lines (lr_coll1), and to try to add them to the new condition lines(lr_coll2):

         lr_collection = lr_admini_new->get_related_entities(
         iv_relation_name = 'BTItemConditionSet' ).
         current ?= lr_collection->get_current( ).
         IF current IS NOT BOUND.
                 current  = lr_admini_new->create_related_entity( iv_relation_name = 'BTItemConditionSet' ).
         ENDIF.
         lr_entity ?= current.
         lr_collection = lr_entity->get_related_entities(
             iv_relation_name = 'BTCondICondLineAll' ).
         current ?= lr_collection->get_current( ).
         IF current IS NOT BOUND AND lr_entity->is_changeable( ) = abap_true.
         current = lr_entity->create_related_entity( iv_relation_name = 'BTCondICondLineAll' ).
         lr_entity ?= current.

                    CALL METHOD lr_entity->get_related_entities
                      EXPORTING
                        iv_relation_name = 'BTCondICondLineAll'  "Get Item Pricing entity which is to be changed
                      RECEIVING
                        rv_result        = lr_coll2.

          if lr_coll1 is BOUND.
            lo_entity1 ?= lr_coll1->get_first( ).
            WHILE lo_entity1 is bound.
            lo_entity2 = lo_entity1.
            lr_coll2->add( iv_entity = lo_entity2 ).
            lo_entity1 ?= lr_coll1->get_next( ).
            ENDWHILE.

         endif.    

Is this the correct approach?

If someone can give some guidance on how to do this, it would be greatly appreciated.

Thanks,

David
