Logic behind it

The Product Information standard identifies the products with LVI-numbers, so LVI-number – column is always obligatory. Another important filed is the Operation – column.

In Operation column you give the system instructions, what should be done with the data in question: if the data is new, in Operation column you’ll fill in the code U, whether you want to change the data in question, you fill in M, or whether you want to delete it, you fill in P.

For example, if you wish to change the GTIN, you can delete all the other columns from the excel-sheet (except LVI-number and operation – columns) and just fill in the new GTIN. Then put “M” in the operation column, and there you have it.
