针对 IDOC 解析函数 IDOC_INPUT_CREDITOR升级后相关报错 解决办法记录

升级前IDOC 正常，升级后产生的问题， 背景外围系统向sap 传输相关数据产生IDOC 报错：

Field LFA1-MIN_COMP. does not exist in the screen SAPMF02K 0120

Field LFA1-TERM_LI. does not exist in the screen SAPMF02K 0120

Field LFA1-CRC_NUM. does not exist in the screen SAPMF02K 0120

Field LFM1-INCO3_L. does not exist in the screen SAPMF02K 0310
Field LFM1-INCO2_L. does not exist in the screen SAPMF02K 0310
Field LFM1-INCOV. does not exist in the screen SAPMF02K 0310

报上述相关错误，查找相关NOTE ，未找到合适的NOTE，DEBUG 分析后找到增强点

?对上面两个FORM 进行增强

增强代码供参考:

"Bulid Range Table
lt_ktokk_r = VALUE #( FOR ls_ktokk IN lt_ktokk ( sign = lc_sign
                                                 option = lc_option
                                                 low = ls_ktokk  ) ).

IF lt_ktokk_r IS NOT INITIAL.
  IF lfa1-ktokk IN lt_ktokk_r AND lfa1-ktokk IS NOT INITIAL.
    IF blfa1-min_comp IS INITIAL.
      blfa1-min_comp =  nodata.
    ENDIF.
    IF blfa1-term_li IS INITIAL.
      blfa1-term_li =  nodata.
    ENDIF.
    IF blfa1-crc_num IS INITIAL.
      blfa1-crc_num =  nodata.
    ENDIF.
  ENDIF.
ENDIF.

?range 表内容是根据业务需求限定的范围，走增强逻辑

310 FORM 增强同上。

经过测试，可以避免上述报错 了
