Primary key in table exists 2 times - how is that possible?

[Floatjitsu]

Hi experts,

could you explain me this:

The values of username are exactly the same, and my primary key consits only the 3 columns, this should not work, apparently it does - but why and how? Is there anything I can do to solve this?

Best regards

What kind of table are you talking about?

Show the definition of the table.

For a standard and sorted internal table the primary key can be non-unique, for a hashed internal table and a database table it can't. And that's that (and what you could also learn from the documentation).

Horst,

" For a standard and sorted internal table the primary key can be non-unique, for a hashed internal table and a database table it can't. "

Read many threads regarding Standard/Sorted/Hashed tables but the above line helped me in understanding the concept much better.Thanks.

Also it's not because there is no difference for human eyes that it is internally true: non displayable characters or conversion-exit can fool the eye...
