M2IF comes with a product import and the apropriate command
import:products therefore. You can find more information about how to invoke the command in the Usage section.
In general the filename for the dedicated MSI import MUST match the following pattern
<PREFIX>_<FILENAME>_<COUNTER>.csv, whereas the default
<FILENAME> is a combination of date and time like
20190608-114344, and the
<COUNTER> is a consecutive number with two digits starting with
01. This results in a filename like
product-import_20190608-114344_01.csv. Additionally an apropriate
.ok file is needed.
ATTENTION: Please be aware that the three parts MUST be separated with an underscore "_" as there is meaning for the bunch import behind its structure.
The unique identifier for the product import is the SKU. The SKU is a mandatory field that has be available in the column
sku on EVERY row of the CSV file.
The structure for the Product import is nearly 100 % compatible with the Magento 2 CSV structure. Have a look at the Magento 2 documentation for a detailed description of the CSV file structure.
Especially for the product import, Magento extends the default CSV format for some special cases called complex data, which provides some kind of data serialization to extend the default CSV format. Magento describes this on a dedicated page on their website. Beside the topics that has been described on that page by Magento itself, there is a column with additional attributes that also uses a complex data format like Additional Attributes.
In addition to the Magento 2 CSV structure, it is possible to add additional columns to allow tier prices and MSI stock data also be part of the product import. Both columns contains serialized data like the additional_attributes column does.
During product import, M2IF extracts the data from the columns and creates separate CSV files. These CSV files are 1:1 the format described for Tier Prices and MSI import in the corresponding sections. After the products have been imported, M2IF imports the tier prices as well as the MSI data.
