Suggested filtering out the records in the DB2EXIT module by DB2AUTH or DB2PLAN column as mentioned in the DIC.Text.
Filter out in USER.SOURCE(#DB2EXIT) module by adding these changes:
%LET USRSDB2= USRSDB2;
And create new member USRSDB2 with the following filter condition:
IF DB2AUTH EQ ‘XXXX’ THEN SKIP_REC=1
The same was mentioned in the document section 10.2.3 output exits;
%LET USRSDB2 = PACKAGE ;
IF DB2AUTH EQ 'XXXX' THEN SKIP_REC=1;
