What is the first step to deactivate the Previous Week Timecards feature?

To deactivate the Previous Week Timecards feature, the first step involves accessing Custom Settings. This is because Custom Settings in Certinia PSA allow administrators to configure various application features, including timecard settings. By navigating to Custom Settings, you can find the specific configuration options that relate to timecard handling, which is where you would manage the feature in question.

User Preferences typically relate to individual user settings rather than administrative settings concerning features for multiple users or the overall system. Updating Expense Reports is related to managing expenses and does not directly pertain to the timecard settings. Changing the Timecard Entry method involves altering how time is logged, which is also not the initial step in deactivating a specific feature like Previous Week Timecards. Therefore, accessing Custom Settings is the correct first step to manage this feature.
