Steps to Reproduce Behavior

  1. Create a program that contains the following code and run the program: 
          USE home()+"samples\data\customer"
      MODIFY  STRUCTURE
      INDEX ON cust_id TAG cust_id DESCENDING
      MODIFY STRUCTURE
      ALTER TABLE customer ADD PRIMARY KEY cust_id TAG cust_id
      MODIFY  STRUCTURE
  2. When the first Table Designer window appears, click the Indexes tab and note both the Order and Type for the Cust_id tag. The Indexes tab name is Index in Visual FoxPro 3.0. Click OK.
  3. Overwrite the Cust_id key when the warning message appears. Click the Indexes tab on the Table Designer window, noting that the Cust_id key is now a regular index type in descending order. Click OK.
  4. Overwrite the Cust_id key again when prompted. Click the Indexes tab of the Table Designer window. The Cust_id key is now a primary index key, but it is in ascending order.
