For example the following shipping fields of One order document are stored in Database table CRMD_SHIPPING.
The data could be read out via function module CRM_SHIPPING_READ_OB.
This blog introduces the step how to generate fake data which will be returned by function module CRM_SHIPPING_READ_OB for unit test purpose.
Step1. Create fake data in Shipping object buffer
DATA: ls_shipping TYPE crmt_shipping_wrk.DATA: lv_order_guid TYPE crmt_object_guid, lv_ship_guid LIKE lv_order_guid, lt_link_com TYPE crmt_link_comt, ls_link_com LIKE LINE OF lt_link_com.CALL FUNCTION 'GUID_CREATE' IMPORTING ev_guid_16 = lv_order_guid.CALL FUNCTION 'GUID_CREATE' IMPORTING ev_guid_16 = lv_ship_guid.ls_shipping-incoterms1 = 'FOB'.ls_shipping-incoterms2 = 'Jerry Fake incoterms'.ls_shipping-guid = lv_ship_guid.CALL FUNCTION 'CRM_SHIPPING_PUT_OB' EXPORTING is_shipping_wrk = ls_shipping.Step2. Create a link between Order and shipping data via function module CRM_LINK_CREATE_OW
ls_link_com-guid_hi = lv_order_guid.ls_link_com-guid_set = lv_ship_guid.ls_link_com-objname_set = 'SHIPPING'.ls_link_com-objtype_set = '12'.ls_link_com-objname_hi = 'ORDERADM_H'.ls_link_com-objtype_hi = '05'.INSERT ls_link_com INTO TABLE lt_link_com.CALL FUNCTION 'CRM_LINK_CREATE_OW' EXPORTING iv_guid_hi = lv_order_guid it_link = lt_link_com EXCEPTIONS OTHERS = 0.Step3. perform read via Object buffer function call
CLEAR: ls_shipping.CALL FUNCTION 'CRM_SHIPPING_READ_OB' EXPORTING iv_ref_guid = lv_order_guid iv_ref_kind = 'A' IMPORTING es_shipping_wrk = ls_shipping.WRITE:/ 'Incoterms1:', ls_shipping-incoterms1.WRITE:/ 'Incoterms2:', ls_shipping-incoterms2.Callstack of link manipulation and object buffer insert and read for Shipping.
