ORA-01422 Error

Hi,

We are working on an EDI package.  We got the follpowing error:

ORACLE error 20000 in FDPSTP

 

Cause:  FDPSTP failed due to ORA-20000: ORA-01422: exact fetch returns more than requested

ORA-06512: at "XXX_PKG", line 3036

ORA-06512: at line 1

Line 3036 is the last line of the package where an raise_application_error command is invoked.  

Here are my questions:

1.  What is FDPSTP?

2.  Secondly, does the FTPSTP failure have anything to do with the fetch failure. 

3.  Can this problem be mitigated by simply adding a ROWNUM = 1 line to every SELECT INTO?  Or is something else going on that could cause this error to be invoked?
