Anaplan throws an error while trying to hide more than 1000+ month line items
My existing view consists of 4 line items with 3 line items showing only All periods and 1 line item showing months and years from 2010 till 2035. I need to add a new line item to this view which should show only All periods similar to remaining 3 line items, but when i am trying to hide months and years it is throwing below error 'Too many listed items in selection definition, maximum 1000'.
I'm not familiar with this error but someone else on the community started getting a similar error. The issue, as it turns out, was related to using Safari as the browser. You might try using Edge or Chrome to see if you have a similar experience. Sorry, that's the only suggest I have. Adding pros @DaanishSoomar@MarkWarren@Misbah
Another approach to this would be to create boolean filters for the items you are seeking to hide based on the dimension. Perhaps in a System module dimensionalized by the dimension you want to filter. You can create logic driven rules for filtering as perhaps you may want to reuse your show/hide logic. Filter based views are generally better than show/hide as you have more control, auditability, and reusability.
Here is a good article/resource on filters. With a dataset perhaps as large as yours, creating filters would be the best way forward from a performance and experience standpoint.
I know that may have been a generalized explanation, feel free to ask questions if you need further clarification.
With regards to the error message, this might be related to the size of the dataset. As @JaredDolich suggested, perhaps try another browser to see if it's a browser related issue. Though I suspect in this case it may be more data related.
