ABAP Proxies external view

Hi

I would like to change the upper case ABAP names to lower case in an external view of ABAP Proxy.

This was possible for

• IV_A to iv_a and
• IV_PART to iv_part

IV_part includes PART_DESC and PART_ID.

Can I change the datatype names in this structure  to lower case ?

Thanks

Kerstin
