Creating an Purshase req in ME51n gets an same valuation type.

Hi Experts,

My Client ask me an issue as below:-

1. When he/she creates a PR in ME51n the valuation type comes as same as 'RM_IMD' for all material. For that material in (MBEW) table valuation type show as 'ESS_IND'.

Please share your thoughts. I attached an screen shot below for refrence.
