CLEAR : LS_EDIDD, LV_STCEG_L, LV_LAND1, LS_ZE1EDK29.
READ TABLE CT_INT_EDIDD INTO LS_EDIDD WITH KEY SEGNAM = ‘ZE1EDK29’.
IF SY-SUBRC NE 0.
READ TABLE CT_INT_EDIDD INTO LS_EDIDD WITH KEY SEGNAM = ‘E1EDK01’.
CLEAR LS_E1EDK01.
LS_E1EDK01 = LS_EDIDD-SDATA.
SELECT SINGLE STCEG_L LAND1 FROM VBRK INTO (LV_STCEG_L, LV_LAND1)
WHERE VBELN = LS_E1EDK01-BELNR.
IF LV_STCEG_L = ‘BE’.
LS_EDIDD-SEGNAM = ‘ZE1EDK29’.
LS_ZE1EDK29-STCEG = TEXT-004.
CASE LV_LAND1.
WHEN ‘LU’.
LS_ZE1EDK29-BEZEI100 = TEXT-001.
WHEN ‘BE’.
LS_ZE1EDK29-BEZEI100 = TEXT-002.
WHEN OTHERS.
LS_ZE1EDK29-BEZEI100 = TEXT-003.
ENDCASE.
LS_EDIDD-SDATA = LS_ZE1EDK29.
APPEND LS_EDIDD TO CT_INT_EDIDD.
