ERP LORD API - Adding ECC custom fields to CRM.

Hi Experts,

I am trying to add custom field to Lean Order (LORD) API. Few of these fields are either added in VBAP table or in custom table in ECC.

I am following documents available in sdn : http://scn.sap.com/docs/DOC-5280 and OSS note1224179.

I have few queries:

In sdn doc > page 11, it says

Code for the Class ZZCL_LOD_INTF_SUPPLY_DATA

IF_LORD_INTF_SUPPLY~DO_PBO_SINGLE

METHOD if_lord_intf_supply~do_pbo_single.

PERFORM zz_sales_order_owner IN PROGRAM sapmv45a IF FOUND .

PERFORM get_no_deal_id_param IN PROGRAM sapmv45a IF FOUND .

1. ENDMETHOD.

My question is where do I find subroutine zz_sales_order_owner and get_no_deal_id_param? Do I need to add these in current screen? Since the fields are already on screen then which subroutine shall I use?

Also at page 11>

BADI_LORD_DO_PAI

Field = custom field

Module = logic written for custom field ( in user exit)

Program = Main program name

METHOD if_badi_lord_do_pai~fill_supply_list.

DATA : ls_supply TYPE tds_field_supply.

IF iv_object_id = 'HEAD' .

**ZZ_OWNER

ls_supply-field = 'ZZ_OWNER' .

ls_supply-module = 'ZZ_SALES_ORDER_OWNER'.

ls_supply-program = 'SAPMV45A'.

ls_supply-on_check = 'R' .

APPEND ls_supply TO ct_supply .

CLEAR : ls_supply .

**ZZ_ZSC_CODE

ls_supply-field = 'ZZ_ZSC_CODE' .

APPEND ls_supply TO ct_supply.

CLEAR : ls_supply.

ELSEIF iv_object_id = 'ITEM' .

ls_supply-field = 'ZZVKAUS' .

APPEND ls_supply TO ct_supply.

CLEAR : ls_supply.

ENDIF.

1. ENDMETHOD.

In above method > it says module = logic written for custom field ( in user exit)> what subroutine name shall I use here? As in on screen it uses Chain and Endchain to process the field values.

Also while checking for other sdn thread I found http://scn.sap.com/thread/1969232 which says the structures CRMST_L2_ITEM_COMV and CRMST_L2_ITEM_COMC should have new fields. But I don’t find these new fields added in these structures. Shall it not be done by AET?

Kindly share how to proceed?

Thanks and Regards,
