The Standard Cost Worksheet Table
A check mark in this noneditable field indicates that you have run the Implement Standard Cost Changes batch job.
If you change the data in the Standard Cost Worksheet after you have run the Implement Standard Cost Changes batch job, for example, by manually changing the new standard cost on a worksheet line, you need to run it again in order to implement the changed data. The check mark in the field will not disappear when you make changes to already implemented data.
