SQL Query with only Duplicates...

I wish I knew how to say what I am trying to accomplish with a query. The fact that I cannot, might explain why I have a hard time developing SQL to extract the data I want. So I thought I would throw an example out to you guys in hopes that you can help me solve the query problem.

Example:
One table called 'BUDGET'. In this table there are many things, but the key fields are employee number (EID), position number (PCN) and funding department id (DID). It is possible for person in one position to be funded from two different departments. And out of all of the data, I simply want to show the guys who have this condition. So given the sample table:

EID PCN DID
---- ---- --------

1000 0070 21212121
1001 0080 32323232
1001 0020 43434343
1020 0080 65656565
1020 0080 76767676
1020 0010 10101010

...Out of all of this sample data, the only guy to show up in my query is EID=1020, PCN=0080. Because he is one guy in the same position being paid from two different departments. The other are either different PCNs or they simply have only one entry. The output would look like:

EID PCN DID
---- ---- --------

1020 0080 65656565
1020 0080 76767676

This could even use a break to look like:

EID PCN DID
---- ---- --------

1020 0080 65656565

            76767676

Again, all other will be ignored. I think I have provided enough of an example to cover the query. The actual table has quiet a few fields but this should be all I require to dig through.

Any idea how to create and SQL or even PL/SQL code to just grab the data I am searching for a report? I have tried counts and in-line views, but I just cannot seem to work out the logic.

Thanks all...
