In DELETE WHERE CURRENT OF I receive a SQLCODE = -100 and delete more than 1 rows.

I have a cursor for update in microfocus, with connection to a database of db2.

In the readings of the fetch, always read a single row, but when I'm going to do the delete / update of this with a where current of the value of the SQLCODE is a -100 and N rows are deleted or modified, respectively, instead of the corresponding current . Any solution? Thanks.
