The table entries are transported as R3TR TABU or R3TR VDAT entries, while maintained via SM30. You can find these using function "Search for Objects in Request/Task", which you can find in transactions SE03 or SE09 (as described by Esti). - This way you can find all requests and tasks, which contain any entry from the table or view.
Alternatively you can look directly into DB table to find particular record directly.
You can do it following way:
- start transaction SE16
- enter the table name E071K
- field OBJNAME is your table
- field TABKEY contains the key of the record
- execute the selection
- field TRKORR then contains the request or task you are looking for...
Keep in mind that client-dependent tables start with client, and the key is concatenation of all the fields and it can contain * (star).
Example: for instance the record for company code DE01 in client 055 in table T001 has the tabkey value
055DE01
For table T001E, to transport all the entries of company code DE01 it would be then
055DE01*
