EWM Screen Exit for /SCWM/MAT1

Dear Experts,

I need to add additional field to material master data on EWM/SCM box in transaction /SCWM/MAT1. Does anyone know what is the Enhancement for that or may be this is something new in SAP world?

I've tried a program which finds enhancement for given transaction code and the ansver was "No Enhancement found", however when I've checked screen layout for screen 3000, function group /SAPAPO/MAT_MASTER, I found subscreen SA_MATLWH_CI where the frame was described as "Enhancement_Fields" which is not seen on the transaction now.

Any Ideas ?

Best Regards,

Tomasz
