Uploading valuation class using BAPI_MATERIAL_SAVEDATA

Hello SDNers,

I am uploading valuation class using BAPI_MATERIAL_SAVEDATA.

In my excel file I had 25 material of different types.

Out of 25 records 13 were uploaded to DB for remaining I got these kinds of errors.

1) The field MBEW-BKLAS/ BAPI_MBEW-VAL_CLASS is defined as a required field; it does not contain an entry.

2) No description transferred

What could be the reason for the following error.
