    }
}

The above program gets attributes of SAP server. It uses direct connection and connection pool.

BAPI for Material master - Number range

BAPI_MATERIAL_SAVEDATA is the BAPI available for Material master creation.

Material number range is (i.e internal or external) depending on the Material type. BAPI_MATERIAL_GETINTNUMBER BAPI can be used for getting material number based on the Material type.

CALL FUNCTION 'BAPI_MATERIAL_GETINTNUMBER' "Assign New Internal Numbers for a Material Type
EXPORTING
material_type = " bapimatdoa-matl_type Material type
* industry_sector = SPACE " bapimatdoa-ind_sector Industry sector
* required_numbers = 1 " bapimatall-req_numbers Set of material numbers required
IMPORTING
return = " bapireturn1 Return Parameter
TABLES
material_number = " bapimatinr Material numbers assigned
. " BAPI_MATERIAL_GETINTNUMBER

BAPI Vendor master data

There is no standard BAPI for Vendor master data. BAPI_VENDOR_CREATE it simply calls the transaction code 'XK01'. It can be used to create an online vendor.

      There are two alternative ways you can follow,

1.First, you can use the function module VENDOR_INSERT - To insert the vendor in vendor master.

2. Creating a custom BAPI using standard API class VMD_EI_API.
VMD_EI_API-->GET_NUMBER - Get Vendor Number
VMD_EI_API-->MAINTAIN - Create vendor
