Vendor Master Sensitive field addition

Hello Team,

I am currently struggling to add ADRC-STR_SUPPL1 - Street 2 field of vendor master into sensitive field list. Work around I thought of adding STR_SUPPL1 field into LFA1 include but it doesn't work as well.

Can someone throw some light on this how should I add this street 2 field into sensitive list ?

Thanks in advance
