Update the master data by not using RSA1

I am planning to use shortcut of the SAP GUI and pass the tcode with field values.

This is the syntax

*<TCODE><SPACE>FIELD_1=VALUE_1;FIELD_2=VALUE_2.......FIELD_N=VALUE_N;DYNP_OKCODE=OKCODE

Example code

*se38 RS38M-PROGRAMM=rsparam;DYNP_OKCODE=SHOP

For our project I need to pass the field values for tcode RSDMD so that we can skip the first screen which is asking for the infoobject name.

Please let me know how to find the field value for the transaction code RSDMD.

Thanks & Regards
