How a data element can be assigned to a package ?

Hello Experts,

I am trying to rename Data element and Domain (by creating new DE / Domain and copying the old one to new) . I am able to create new, copy old-one to new-one and delete old-one and also activating the new-one, but still i have problems.

1. How will i assign the newly generated DE to a package ? (if i use DDIF_DTEL_PUT)

2. How to suppress pop-up which asks for dev class ? (if i use rpy_dataelement_insert)

If i use DDIF_DTEL_PUT it will not assign it to package and if i use RPY_DATAELEMENT_INSERT it will show pop-up which i don't want.

Please help me.

Thanks and Regards,

Ankur Sharma.
