Solution 2

This script returns all challanid with multiple invoiceid.

SQL

SELECT  challanid
FROM    tbl_invoice_challan
GROUP
BY      challanid
HAVING  COUNT(DISTINCT  invoiceid) > 1

Solution 1

SELECT *
FROM Test AS zd
WHERE (SELECT count(*) FROM Test AS t1
     WHERE = zd.liefschnum AND t1.pos = zd.pos) > 1

This is my sample query. Based on this you develop it for yours.
