Once in a while the resource percentage showing on the task bar becomes too much. If you are wondering what I mean, take a look at this screen shot:
See how each resource has the percentage shown after it? That happens whenever the resource is not assigned at exactly 100% to the task. When you update your schedule with actual work it is very likely that the resource will not longer be at a perfect 100%. The simple answer is to change the barstyle so that the text shown is the Resource Initials rather than the resource name. To do this, go to the format menu and select barstyles. Select the bar you want to edit and click on the Text tab in the bottom half. Change resource names to resource initials. Now, there is one more thing to do. Go to the resource sheet. Make sure it shows the resource intials column. Select the resource name column, then choose "copy" or CTRL+C. then select the resource initials column and paste CTRL+V the information into that column.
