Implementation of BAPI functions for SAP MM in BODS

Hi Experts,

I am new to BAPI, SAP MM module and I need your help here. I am trying to create a Material Master record in MARA table by implementing following BAPI functions in SAP BODS:

BAPI_MATERIAL_GETINTNUMBER : To get internally generated MATNR (Material Number)

BAPI_MATERIAL_SAVEDATA         : To create the record in MARA table

BAPI_TRANSACTION_COMMIT       : To commit the transaction

I am trying to pass values, for following columns, from a flat file to ECC system:

MANDT;ERSDA;ERNAM;VPSTA;PSTAT;MTART;MBRSH;MATKL;MEINS;MAKTX;MAKTG;SPRAS

Questions are:

1. Are there any other mandatory columns, apart from the ones mentioned above, for which I need to pass value to the transforms in order to create a Material (Basic Data 1 View)?

2. I can see there are two types of input parameters (Scalar and Table) in each BAPI functions mentioned above. I am not able to map those input parameters. Are they all mandatory parameters?

Any advice, suggestion would be of great help.

Thanks,

Purnima
