Raw Material Classification ?

Hi All,

Weare facing a problem during uploading material classification, using BAPI "BAPI_OBJCL_CREATE" , or BDC using transaction "CLMM" , or LSMW using transaction "CL20N". Each material classification upload is

taking nearly 2 hours. Each material is to be assigned 1 class of class type 200 and with 370 characteristics along with values. There are more than 1500 materials to be maintained.

Thanks & Regards

Navneeth K.
