AS/400 POS Import

What is this?

AS/400 is a legacy IBM midrange system still used by some retailers. Margin Master imports AS/400 data exports to build pricing analysis tables.

Margin Master reads the standard export your AS/400 system produces; support confirms the layout 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. Export your data from the AS/400 system as a .txt file, using the export Margin Master support confirmed with you.
  2. Place the file in the configured import folder.
  3. Margin Master reads and validates the file, then loads the data into its database.
  4. Margin Master joins the store data with vendor catalog data to build your main pricing analysis table.

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 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
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

  • Simple field set: AS/400 has one of the more straightforward export layouts. If your export matches the one confirmed at setup, the import should work without additional configuration.
  • Category becomes Department: the category from your AS/400 export is what you see as the Department in Margin Master.

Common Questions

Q: Can I change the layout of my AS/400 export? A: Margin Master expects the export layout confirmed with you at setup. If your export changes, contact Margin Master support with a sample file before importing it.

Q: Some of my values are very long. What happens to them? A: Margin Master trims values that are longer than its fields allow. If you notice a trimmed SKU or description, contact Margin Master support with the file.
