If your Retail Pro v8 Shuttle stops running, follow these steps to diagnose and resolve common issues:

1. Departments Have Been Added or Removed

Issue:
Adding or removing DCS codes (departments) in Retail Pro causes Shuttle to lose track of the mapping, resulting in errors.

Solution:

1. Open the Shuttle program.

2. Attempt to launch Shuttle for the current month’s data load.

3. If you receive an error about department mismatches:

   • Click OK on the error messages.
   • Click Menu, then select Class Mapping.

4. If a DCS code was added:

   • Locate entries marked "UNLINKED."
   • Assign the correct M1 Class code or use "IGNORE" to exclude it from Shuttle.

5. If a DCS code was removed:

   • Any obsolete mapping will be highlighted in red.
   • Click DELETE to remove these entries.

6. Click SAVE and exit the Shuttle program.

7. Restart Shuttle and attempt the data load again.

2. No Valid Workstation

Issue:
Shuttle will not run if the environment is missing a valid Retail Pro workstation configuration.

Solution:

1. Ensure there is a valid RPROWS system variable:

   • Press Win + R, type sysdm.cpl, and press Enter.
   • Go to the Advanced tab → Click Environment Variables.
   • Check for a System Variable named RPROWS.
   • Ensure its value corresponds to a valid Retail Pro workstation (e.g., 1).

2. If missing, click New…, add the variable:

   makefile

    

   Variable: RPROWS Value: 1

3. Restart your computer and rerun Shuttle.

3. No Valid Pathing

Issue:
Shuttle cannot locate Retail Pro directories if the path is not set.

Solution:

1. Verify PATH system variables:

   • Open Environment Variables (see steps above).
   • Ensure these two directories are present in the PATH variable:
     makefile

      

     C:\Retail\ C:\Retail\Rpro\

2. If missing, click Edit and add the above paths.

3. Restart your computer and try launching Shuttle.

4. RDA2.dll Not Registered

Issue:
Shuttle fails if it cannot connect to the Retail Pro database due to an unregistered RDA2.dll.

Solution:

1. Open Command Prompt with Administrator privileges:

   • Click Start, type cmd.
   • Right-click Command Prompt → Select Run as Administrator.

2. Register RDA2.dll by entering the following command:

   mathematica

    

   REGSVR32 C:\Retail\Rpro\RDA2.dll

3. You should see a confirmation message indicating successful registration.

4. Restart your computer and attempt to run Shuttle.

Final Check

• Ensure the Shuttle program is up-to-date.
• Confirm the Retail Pro database is accessible and functional.
• If issues persist, contact Retail Pro Support for further assistance.
