We previously received a warning flag if we entered a Item Number that was not on the BOM.  We would be asked if we would like to add the number to the BOM and could not proceed without answering yes or no.
This was helpful in preventing keying errors.
 
We are training a new operator and would like to turn this feature on if it is still available.
 
We are using Version 2004.1 with ISTech update 07/05/04 - Microsoft Small Business Server 2000
 
Thanks
