I have been having a devil of a time trying to update a product with new combinations. I basically need to append to the database, but it seems to be overwriting it with each new .csv upload. I have tried all combinations of settings in Store Manager's import feature.

Is this characteristic of how Prestashop works or am I possible setting up the columns in my .csv file incorrectly? I would prefer to be able to upload many spreadsheets instead of compiling them all into one.

Hello Jblack!

Thank you for your post.

Product Import Wizard allows to update product details (including product combinations).
Product Combinations can not be updated, while product import. They can be regenerated only, that's why your .csv file should contain all details combination consists of.

So in order to update combination quantities, your .csv file should contain product identifier (Reference or EAN etc) and all combination related data.

Hello Volodymyr,

Thank you for your quick response. I ended up using a script to combine my import .csv files into one. I tested with two spreadsheets combined, which was about 1100 records. Although the combinations imported into the product specified by the sheet, for some reason an attribute was missing. If I import fewer records, however, the attribute imports fine.

The main point of using Prestashop in the first place was because of its ability to import my pricing data. Any ideas on why this could be happening?

Please submit a ticket at: http://support.emagicone.com/submit_ticket and attach your .csv file and import configuration file (may be saved at the last step of Import/Export Wizard), so we could check it more deeply and advise you on this regard.
