BAPI - MR21 Price Updation

Hi,

I want to update the Material Price through tr. code MR21.

I got below bapi to upload the price.

PRICES_CHANGE

PRICES_POST

BAPI_M_REVAL_CREATEPRICECHANGE

BAPI_MATVAL_PRICE_CHANGE

But, all are not relevant or not working for uploading price.

Please suggest the same if any BAPI or any other method to upload.

Regards

Amol Khochare
