Updating an Activity Id requires that you first QUERY the activity that needs updating. Refer to the previous section, Querying an Activity, for information on how to do this. Only the Description field and the Budgeted Figures field can be updated. When the desired activity is displayed, the screen must be put into the UPDATE mode by pressing the UPDATE <F4> button. The TAB key is used to move the cursor to the field to be updated. The new data is typed into the field and then the STORE <F5> button is pressed to store the changes.
