RockSolid POS Import

What is this?

The RockSolid import reads inventory and sales data from the export file RockSolid produces (a .RS file) and loads it into Margin Master for pricing analysis. RockSolid pairs with Do it Best vendor data.

Walk through it in the app: guide 4009 — Importing your RockSolid data. Margin Master can walk you through these steps live: turn on Training / Guide Mode from the Help menu, then type 4009 into the Lessons & Guides box — or ask Margin Master support to run it with you.

RockSolid does not produce a text file. Margin Master opens the .RS file directly, through a Microsoft database driver that it installs for you (see OLEDB Driver). Support confirms the export with you at setup.

How Import Works

Data menu - the import command is labelled for your POS system

The export file is read from the Import Path set under Tools > Options > Miscellaneous:

Import/Export Paths on the Miscellaneous tab

  1. Run RockSolid's export for Margin Master so the .RS file is current, and make sure it is in the configured import folder.
  2. Margin Master opens the .RS file and reads your inventory and sales data from it. No text file is created.
  3. The data is loaded into Margin Master's database.
  4. A main table is built for each store in the export.
  5. Each main table is enriched with Do it Best vendor catalog data for pricing analysis.

Troubleshooting

Symptom Likely cause What to do
No Files Found when you choose Get POS Data The export is not in the Import Path (Tools > Options > Miscellaneous), or its name does not match the .RS file name Margin Master support confirmed with you Check the path and the file name; Margin Master reads only the current folder, not sub-folders
The same file is imported again and again The previous import's file was not renamed After a successful import the file is renamed to NAME[ext].BAK; a file that keeps its name did not import - read the error dialog
0 records or far fewer than expected The export covers the wrong store, or the store is not matched in the Store Manager Open Store Manager and check the store's row; re-export from the point of sale
Columns land in the wrong fields The export layout changed Contact Margin Master support with the file
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine The database driver Margin Master needs is not installed Tools > Options > RockSolid > Install OLEDB Driver; see OLEDB Driver
Import finishes but the grid does not change The rebuild was postponed (the Click to update data badge is showing) Click the badge, or Data > Rebuild Data

Every import failure shows one error dialog; the log under File > Utilities > Show Log Files has the detail to send to support.

OLEDB Driver

Margin Master opens the .RS file through a Microsoft database driver. Without it the import fails with The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine, and the price export to RockSolid fails the same way.

Tools > Options > POS / Connections > RockSolid shows the driver's status (1) and has one button (2):

RockSolid tab with the OLEDB driver status and button

  • Install OLEDB Driver (shown when the driver is missing) downloads the driver from Microsoft and installs it. Windows asks for administrator permission. Margin Master then checks the driver again and reports the result; a restart of Windows is occasionally required.
  • Verify OLEDB Driver (shown when the driver is present) confirms the installation and reports what it checked.

Margin Master also checks for the driver each day when it starts on a RockSolid store and offers the same installation if the driver is missing. If the installer refuses to run -- this can happen when Microsoft Office is installed on the same computer -- ask Margin Master support; there is a procedure for it.

Tips

The database driver must be installed. If Margin Master cannot open the RockSolid file, open Tools > Options > RockSolid and click Verify / Install OLEDB Driver (see OLEDB Driver above).

RockSolid also supports export. After pricing analysis, Margin Master can write future prices back to RockSolid so you can import the updated prices into your POS system.

Common Questions

Q: What vendor data does RockSolid use? A: RockSolid pairs exclusively with Do it Best vendor data. Your Do it Best catalog must be synced before building main tables.

Q: Do I need to export from RockSolid first? A: Yes. Run RockSolid's export for Margin Master before you choose Get POS Data, so the .RS file holds current data.

Q: Why are my store numbers different after import? A: Margin Master removes leading zeros from store numbers. For example, store 007 becomes 7.

Q: Can I import multiple stores at once? A: Yes. If the RockSolid export contains more than one store, Margin Master creates a separate main table for each store it finds.
