Request for externals on page 7002 "Sales Prices"

[exnihiloo]

Why do you need this change?

1. We are extending Page 7002 "Sales Prices" using a page extension and have a requirement to reuse the existing filtering logic.
   The page internally uses the following global variables:

   StartingDateFilter
   CurrencyCodeFilter

   These variables are essential for filtering sales price data and are already used within the standard application logic. However, they are currently not accessible from page extensions, which limits the ability to create consistent and reusable customizations.

   When implementing custom actions or logic in a page extension of page 7002, we cannot:
   Access the current values of StartingDateFilter and CurrencyCodeFilter
   Reuse standard filtering logic already applied by the page
   Ensure consistency between standard filtering behavior and custom functionality

   As a result, we are forced to:
   Duplicate filtering logic manually
   Maintain separate custom variables
   Risk inconsistencies with future Microsoft updates

   This limitation leads to:
   Reduced extensibility of standard pages
   Additional development and maintenance effort
   Increased risk of discrepancies between standard and custom behavior
   Less upgrade-safe customizations

2. On Page 7002 "Sales Prices", the procedure GetRecFilters() is currently defined as local, which prevents it from being accessed or reused in page extensions.
   This procedure contains important standard logic responsible for:
   Processing record filters
   Calling internal filtering logic (UpdateBasicRecFilters)
   Assigning StartingDateFilter based on the current page filters
   Because GetRecFilters() is local:

   Extensions cannot invoke standard filter processing logic
   Developers must replicate internal logic manually
   The dependency on UpdateBasicRecFilters() makes correct reimplementation difficult
   There is a risk of inconsistent behavior compared to the base application

Describe the request

1. We are requesting the following variables protected so they can be accessed in page extensions:

   protected var
           StartingDateFilter: Text;
           CurrencyCodeFilter: Text;

2. Change the scope of the procedure from local to global

   procedure GetRecFilters()
       begin
           if Rec.GetFilters() <> '' then
               UpdateBasicRecFilters();
   
           Evaluate(StartingDateFilter, Rec.GetFilter("Starting Date"));
       end;
