+description: The Data Controller roadmap is aligned with the needs of our customers - we continue to build and prioritise on features requested by, and funded by, new and existing customers.

+
+# Roadmap
+
+## Overview
+
+On this page you can find details of the features that have currently been requested, that we agree would add value to the product, and are therefore in our development roadmap.
+
+Where customers are paying for the new features (eg with our discounted Developer Days offer), then those features will always take priority.  Where funding is not available, new features will be addressed during the Bench Time of our developers, and will always be performed after Bug Fixes.
+
+If you would like to see a new Feature added to Data Controller, then let's have a chat!
+
+
+## Requested Features
+
+### Dynamic Filtering
+
+#### Problem Statement
+
+The existing filter box provides a list of values when selecting operators such as "IN", "=" etc.  The problem is that this dropdown does not consider existing filter selections.  So if a user filters on, say, "region", and then filters on "store", they will see stores for ALL regions (not just the region/regions already selected in the filter).

+
+#### Proposed Solution
+
+We add a checkbox to the top right of the filter dialog (default ON) for "Dynamic Filtering".  Whilst enabled, whenever a list of values is requested, it is filtered using every filter clause EXCEPT the one currently being modified.
+
+#### Technical Implementation
+
+It will be necessary to first ensure that every filter clause is valid (currently, it is possible for two clauses to be invalid whilst they are being worked on).  We will need several (automated) test cases in the cypress suite:
+
+* Simple (just two clauses)
+* Multiple clauses (up to 6)
+* Multiple grouped clauses
+* Very large clause (so that filter query exceeds 50k characters)
+* An attempt to work on several clauses in quick succession
+* Both character & numeric
+
+Currently when calling the 'public/getcolvals' service we provide a single table (iwant) with two values (libds & col).  This service needs to be extended to include an additional input (filtertable) with one column (filterline).  The filter query will be split across multiple rows in this table.
+
+The service will need to safely validate this input query, to prevent the risk of SQL injection.  It can then be used to filter the returned output.
+
+Additional automated SAS tests required:
+
+* malicious code injection
+* Very large clause (so that filter query exceeds 50k characters)
+* accuracy checks
+
+
+
+## Delivered Features
+
+### Configurable Locale
+
+#### Problem Statement
+
+When importing spreadsheets with ambiguous dates (eg 01/02 or 02/01) the ANYDTDTM. informat was using the locale of the browser (en_us) instead of that of the client's actual country, resulting in incorrect dates being loaded.  This is due to the [default behaviour](https://rawsas.com/look-out-locale-gotcha/) of the SAS Stored Process server.
+
+#### Solution
+
+We added a [new config item](/dcc-options/#dc_locale) so that the locale can be explicitly set for all Data Controller users.
