Warning: "The time periods requested do not exist" moving through periods on a TSV field

Issue/Introduction

Receive an alert when trying to scroll through (move to future or past periods) in a portlet grid or after changing time-scaled (TSV) view configurations within views/portlets such as

• Home - Project - Team - Detail
• Home - Resource - Allocations - Detail

The warning received is "Alert: The time periods requested do not exist. Review the column's Time Scale settings". 

Is there a way to extend the date ranges for Time Slices in Clarity so this issue doesn't happen?

Environment

Release: All Supported Releases
Component: Clarity Time Slices

Cause

• This is not an error message, but a warning that the information cannot be displayed due to date range constraints. 
• The alert is given when the limit of the following availability internal time slices is reached: D_AVL, W_AVL, M_AVL.
• There are external and internal slices that exist in Clarity. Internal slices are not exposed in the Administration > Data Administration > Time Slices page, due to potential performance issues.
• The reason you do not see any values in the time scaled portion when you receive the warning is because the query that runs to retrieve the periods looks at the first period and last period in your number of periods and if there is not a matching value in the tables mentioned above, the query cannot run and provide any data.

Resolution

1. If you are outside of the below range - please use the correct range of periods
   • The out-of-the-box internal timeslice range is as follows:
     • 28 Daily - 7 days in the past, the current day and 3 weeks in the future
     • 16 Weekly - 2 weeks in the past, the current week and 13 weeks in the future
     • 36 Monthly - 4 quarters in the past, the current quarter and 7 quarters in the future
2. If a longer period is needed, consider switching to Modern UX where there is no limitation.
3. Approved Internal Time Slices Extension which will add few more periods to the range. This is a pre-approved new internal timeslice range customization that can be used strictly as is (SaaS / GCP Customers please contact Broadcom support).
4. To apply it - download the attached ZIP file and follow the instructions in the text file.
   • After applying it, the range will be set accordingly: 
     • 42 Daily - 7 days in the past, the current day and 4 weeks in the future
     • 45 Weekly - 4 weeks in the past, the current week and 40 weeks in the future
     • 51 Monthly - 4 quarters in the past, the current quarter and 12 quarters in the future
