RockSolid POS Import

What is this?

The RockSolid import reads inventory and sales data from a RockSolid POS Microsoft Access database file (.RS) 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.

Import File Format

RockSolid does not use a text file. Instead, Margin Master connects directly to the RockSolid Access database (.RS file) using an OLEDB connection.

  • File type: Microsoft Access database (.RS extension)
  • Source table: MMExport (inside the Access database)
  • Driver required: Microsoft ACE OLEDB 12.0
# Field Description
1 ProductCode Product code identifier
2 Description Item description
3 AverageCost Average cost of the item
4 Retail Current retail price
5 Inventory Current inventory on hand
6 Department Department name
7 Class Class name
8 SubClass Sub-class name
9 Location Store location code
10 Sku Item SKU (automatically uppercased)
11 QuantityRank Sales ranking by quantity
12 Store Store number (leading zeros removed)
13-25 H0 through H12 Monthly sales history (13 periods)

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. Margin Master opens the RockSolid Access database (.RS file) using the Microsoft ACE OLEDB 12.0 driver.
  2. It reads all rows from the MMExport table inside the Access database.
  3. SKU values are automatically converted to uppercase for consistency.
  4. Leading zeros are trimmed from store numbers.
  5. The data is written directly to the [RockSolid] SQL Server table using a bulk copy operation (no intermediate text file is created).
  6. Per-store main tables are built with the naming pattern RockSolid_{Store}_mainTable.
  7. 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 pattern above 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 Compare the file's header row with Field Mapping above; contact Margin Master support with the file
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.

Tips

Microsoft ACE OLEDB 12.0 driver must be installed. If Margin Master cannot connect to the RockSolid database, verify that the 32-bit or 64-bit ACE OLEDB driver is installed to match your Margin Master installation.

The .RS file is a renamed Access database. Even though the extension is .RS, it is a standard Microsoft Access file that Margin Master reads via OLEDB.

RockSolid also supports export. After pricing analysis, Margin Master can write future prices back to the MMImport table in the RockSolid Access database, allowing you to import updated prices into your POS system.

SKU + Store is the unique key. Each record is identified by the combination of SKU and Store number. Duplicate combinations will be overwritten during import.

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. RockSolid must populate the MMExport table in its Access database before Margin Master can read the data.

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

Q: Can I import multiple stores at once? A: Yes. The MMExport table can contain data for multiple stores. Margin Master will create separate main tables for each store found in the data.
