SAP ESS_ Communication_Email ID field edit

Hi All,

I need your expertise help in ESS Application. we have requirement to make Email filed edit in ESS application.( Communication infotype and subtype AU02)

Currently the field is in non-editable mode, we would like to make it as editable mode.

I have tried playing around with table :(V_T588MFPROPC) :(V_T588MFPROPS), there is one more other view table where defining Subtypes for ESS. but so no luck.

please help me out to addressing this issue.

Many thanks,

Ashok
