Alias field update in ABAP system

Hello Everyone,

Need your input in updating Alias field under SU01 (User master record) when we create new user in IdM.

For example if we are creating new user "ABCD1234" from IdM, when this id created in ABAP, alias field should also populate with ABCD1234@XYZ.NET"

Please share your input or guidance on achieving this requirement, we are using IdM 7.2 (SP9).

Regards,

Manish
