When attempting to MERGE in Fulfillment Center (any document) the error 6501 "undefined error msg @" is displayed.
The problem is the Fulfillment Center is attempting to send EMAIL and is having problems communicating with the email application. In Fulfillment Center click the OPTIONS menu and uncheck the option "EMAIL WHEN ABLE" and retry the merge. The merge should work at this point. The option to EMAIL WHEN ABLE defaults to on/off based on the USER SETTING for the user logged in. Look under OPTIONS + USER SETTINGS and the GENERAL tab and if the USEEMAIL is set to 0 change to 1 and SAVE if you do not want to email from WINSALES. If you do wish to use email with WINSALES review sup163.htm
Users running older versions of WINSALES may also encounter this error. If you are not running 5.0.92 of Fulfillment Center run
