0MAT_PLANT_ATTR enhancement issue

Hi All,

I am working on the 0MAT_PLANT_ATTR datasource enhancement wherein I am extracting data for fields like

1. Reorder Levels – MINBE – (BIW_MARC_S)
2. Safety Stock - EISBE - (BIW_MARC_S)
3. Min. Lot Size – BSTMI – (BIW_MARC_S)
4. Rounding Value - BSTRF –(BIW_MARC_S)
5. Lot Size Key - DISLS - (BIW_MARC_S)
6. Plant Mat Status – MMSTA - 0MAT_PLANT_ATTR - - present in the DS
7. Cross Plant Mat Status – MSTAE- 0MATERIAL_ATTR (ES - BIW_MARA_S)

--The issue is I have written a code in cmod -EXIT_SAPLRSAP_002 - to fetch data for field no. 1-7 as they are hidden in the datasource and also use MEINS (Base unit of measure) field of table MARA as reference.

In RSA3, when i execute I am unable to see the data for MEINS and MSTAE - Cross Plant Mat Status fields. both the fields are part of MARA table and not MARC which is the base for 0MAT_PLANT_ATTR datasource.

--Also could you please tell me about the delta functionality of this? I went through some posts which tell me to add field entries to BD52. In ROOSGEN table the message no. is RS0127. I am unable to understand the relevance.

Code:

DATA : wa_mara type mara,

C_T_DATA_TAB TYPE TABLE OF BIW_MARC_S,

C_T_DATA_WA TYPE BIW_MARC_S.

WHEN '0MAT_PLANT_ATTR'.

LOOP AT C_T_DATA_TAB INTO C_T_DATA_WA.

L_TABIX = SY-TABIX.

select single * from mara into wa_mara

where matnr = C_T_DATA_WA-matnr.

IF SY-SUBRC = 0.

C_T_DATA_WA-zzmeins = wa_mara-meins.

C_T_DATA_WA-zzeisbe = C_T_DATA_WA-eisbe.

C_T_DATA_WA-ZZMINBE = C_T_DATA_WA-MINBE.

C_T_DATA_WA-zzBSTMI = C_T_DATA_WA-BSTMI.

C_T_DATA_WA-zzBSTRF = C_T_DATA_WA-BSTRF.

C_T_DATA_WA-zzMMSTA = C_T_DATA_WA-MMSTA.

C_T_DATA_WA-zzMSTAE = wa_mara-MSTAE.

MODIFY C_T_DATA_TAB FROM C_T_DATA_WA INDEX L_TABIX .

ENDIF.

ENDLOOP.

Thanks.
