BAPI or Function module for WAHD2

Hi all,

Is there any BAPI or function module to update consumption values in the t-code WAHD2 ?

I found one WAHD_DISPLAY_CHANGE but when I executed this, it is opening another page where we can edit the values like in the t-code. So I am not sure how to use this inside my program.

Please share your valuable thoughts on this.

Thanks.
