1、文档说明
本方法是将新增字段,展示在MIGO的新增页签中,并保存到自建表。
新增页签的方法,和采购订单新增页签的方法原理基本一致,都是需要创建函数组,并实现相应方法和屏幕,并在增强中调用该函数组,展示出屏幕,实现对应操作。
2、实现过程
2.1、创建自建表和结构
自建表中存储物料凭证主键和增强的字段ZNUM单据号
参考自建表,创建对应的结构,用于函数组数据传递
创建表类型,用于增强实施类

READ TABLE it_item INTO wa_item_old WITH KEY line_id = i_line_id. IF wa_item_new-line_id i_line_id. e_force_change = 'X'. ENDIF. ENDMETHOD. "--------------------@斌将军--------------------
2.2.5、实现MODIFY
实现增强方法IF_EX_MB_MIGO_BADI~LINE_MODIFY
"--------------------@斌将军-------------------- METHOD if_ex_mb_migo_badi~line_modify. DATA: wa_item_new TYPE zspp001, wa_item_old TYPE zspp001, wa_ztmm_i_migo01 TYPE ztpp001, l_subrc TYPE sy-subrc. READ TABLE it_item INTO wa_item_old WITH KEY line_id = i_line_id. l_subrc = sy-subrc. IF sy-subrc 0. IF cs_goitem-mblnr IS NOT INITIAL AND cs_goitem-mjahr IS NOT INITIAL AND cs_goitem-zeile IS NOT INITIAL. SELECT SINGLE * FROM ztpp001 INTO wa_ztmm_i_migo01 WHERE mblnr = cs_goitem-mblnr AND mjahr = cs_goitem-mjahr AND zeile = cs_goitem-zeile. IF wa_ztmm_i_migo01 IS NOT INITIAL. MOVE-CORRESPONDING wa_ztmm_i_migo01 TO wa_item_new. ENDIF. ENDIF. wa_item_new-line_id = i_line_id. INSERT wa_item_new INTO TABLE it_item. ELSE. CHECK g_line_id = i_line_id. CALL FUNCTION 'ZEMIGO_GET_DATA' IMPORTING e_out = wa_item_new. * wa_item_new-line_id = i_line_id. MODIFY it_item FROM wa_item_new TRANSPORTING znum WHERE line_id = i_line_id. ENDIF. ENDMETHOD.

2.2.6、实现DELETE
实现增强方法IF_EX_MB_MIGO_BADI~LINE_DELETE
"--------------------@斌将军-------------------- METHOD IF_EX_MB_MIGO_BADI~LINE_DELETE. DELETE TABLE it_item WITH TABLE KEY line_id = i_line_id. 服务器托管网ENDMETHOD. "--------------------@斌将军--------------------
2.2.7、实现RESET
实现增强方法IF_EX_MB_MIGO_BADI~RESET
"--------------------@斌将军-------------------- METHOD IF_EX_MB_MIGO_BADI~RESET. * Clear all internal data: CLEAR: gt_extdata, g_no_input, gs_exdata_header, g_cancel, it_item, g_line_id. ENDMETHOD. "--------------------@斌将军--------------------

2.2.9、控制编辑状态
可以通过里面对应的ACTION,来控制增强字段的显示效果,比如在A04显示物料凭证时,设置增强字段为不可更改
创建函数ZEMIGO_SET_GOACTION接收ACTION
实现屏幕流

"--------------------@斌将军-------------------- METHOD if_ex_mb_migo_badi~mode_set. * ACTION and REFDOC will discribe the mode of transaction MIGO. * ---------------------------------------------------------------------- * i_action: * A01 = Goods receipt * A02 = Return delivery * A03 = Cancellation * A04 = Display * A05 = Release GR bl.st. * A06 = Subsequent deliv. * A07 = Goods issue * * i_refdoc: * R01 = Purchase order * R02 = Material document * R03 = Delivery note * R04 = Inbound delivery * R05 = Outbound delivery * R06 = Transport * R07 = Transport ID code * R08 = Order * R09 = Reservation * R10 = Other GR *----------------------------------------------------------------------- * In case of 'DISPLAY' the global field G_NO_INPUT will be set to 'X'. * The result is that a different external subscreen will be choosen in * method PBO_DETAIL. IF i_action = 'A04' OR i_action = 'A03'. g_no_input = 'X'. ENDIF. * In case of 'CANCEL' the global field G_CANCEL will be set to 'X'. * The result is that in method POST_DOCUMENT a different handling is * used IF i_action = 'A03'. g_cancel = 'X'. ENDIF. CALL FUNCTION 'ZEMIGO_SET_GOACTION' EXPORTING i_goaction = i_action. ENDMETHOD. "--------------------@斌将军--------------------
