While excuting the same code on tmp2.milkprod works fine, the data are different in the two data sets.

Redha,

ODS is complaining because WORK.COWS and WORK.FIXED are already assigned as ODS OUTPUT data sets. Why that is the case cannot be determined from the code fragment. Presumably they were assigned in previously executed code.

I recommend that you contact Technical Support with this problem. You can submit it online at http://support.sas.com/ctx/supportform/index.jsp .
