Problem with Sales view for BAPI_MATERIAL_SAVEDATA

Hi,

I am trying to extend material using BAPI_MATERIAL_SAVEDATA.

Basic, Plant, Sales, Accounting view are required.

Everything is working fine except sales view. But when I tried to include sales view, it's giving error "Field MVKE-MVGRP1 is MANDATORY" and it's asking the values for these 5 MVGRPs.

But when we cretae/extend material using "mm01", it does not ask for this field.

I have written below code for sales view.

BAPI_MVKEX-SALES_ORG = INT_MAT-VKORG.

BAPI_MVKEX-DISTR_CHAN = INT_MAT-VTWEG.

BAPI_MVKEX-ITEM_CAT = 'X'.

BAPI_MVKEX-CASH_DISC = 'X'.

BAPI_MVKE1-SALES_ORG = INT_MAT-VKORG.

BAPI_MVKE1-DISTR_CHAN = INT_MAT-VTWEG.

BAPI_MVKE1-ITEM_CAT = INT_MAT-MTPOS.

BAPI_MVKE1-CASH_DISC = INT_MAT-SKTOF.

Appreciate any help.

Thanks,

Saurabh.
