But when I have more than 1 iteration only the last iteration goes threw the whole codes correctly, all previous ones skip a step. B/C of these 3 similar errors. I did try to close the files with CLOSE FUNCTION but it did not work. Any help is greatly appreciated. <BR /> RG<BR /> <BR /> ERROR: You cannot open WORK.ITEMBYCLASS.DATA for output access with member-level control<BR /> because WORK.ITEMBYCLASS.DATA is in use by you in resource environment DMS Process.<BR /> NOTE: The SAS System stopped processing this step because of errors.<BR /> NOTE: DATA statement used (Total process time):<BR /> real time 0.00 seconds<BR /> cpu time 0.00 seconds<BR /> <BR /> ERROR: You cannot open WORK.CLASSLEVEL.DATA for output access with member-level control because<BR /> WORK.CLASSLEVEL.DATA is in use by you in resource environment DMS Process.<BR /> NOTE: The SAS System stopped processing this step because of errors.<BR /> NOTE: DATA statement used (Total process time):<BR /> real time 0.00 seconds<BR /> cpu time 0.00 seconds<BR /> <BR /> ERROR: You cannot open WORK.ITEMBYTHRESH.DATA for output access with member-level control<BR /> because WORK.ITEMBYTHRESH.DATA is in use by you in resource environment DMS Process.<BR /> NOTE: The SAS System stopped processing this step because of errors.<BR /> NOTE: DATA statement used (Total process time):<BR /> real time 0.00 seconds<BR /> cpu time 0.00 seconds Wed, 09 Mar 2011 20:16:38 GMT https://communities.sas.com/t5/SAS-Procedures/ERROR-MEMBER-LEVEL-CONTROL/m-p/25441#M5772 R_A_G_ 2011-03-09T20:16:38Z https://communities.sas.com/t5/SAS-Procedures/ERROR-MEMBER-LEVEL-CONTROL/m-p/25442#M5773 Which procedures are generating these messages?
