When trying to import multiple rate cards on your instance you should provide the Support with created .csv files.
The template file is attached. Provided files should be one file per user/LSP.

A .csv file needs to be provided by the client for each user/LSP,  where rate cards need to be added. Such file should be built specifically:

 Data from template:

lsp id;client;user id;;;;;;;;;;;;;;;;;
;mpera2;488169;;;;;;;;;;;;;;;;;
ratecard name;description;activity;language combinations;subject matter;calculate using;charging type;Base Rate;Words Per day;Minimum Charge;Fixed price per project;Fixed price per language;Fixed price per file;Management fee;Currency;;;;;

First line - this is a header and should not be changed

lsp id;client;user id;;;;;;;;;;;;;;;;;;


Second line - either lsp id or user id should be provided, not both! Note that the client field is required as it should be referred to as the company name the rate card is being imported to.
Example for the user:

;mpera2;488169;;;;;;;;;;;;;;;;;

Example for the LSP:

123123;mpera2;;;;;;;;;;;;;;;;;;


NOTE: The LSP/user ID needs to be provided by the account ID (see screenshot below) and not from the LSP connection field.


 

Third line - general header, should not be changed

ratecard name;description;activity;language combinations;subject matter;calculate using;charging type;Base Rate;Words Per day;Minimum Charge;Fixed price per project;Fixed price per language;Fixed price per file;Management fee;Currency;;;;;;


The headers indicate to this part of the rate card

Fourth line - breaking line that shouldn't be changed. It may seem empty but when you edit the file in Excel/OpenOffice Calc/Notepad++ it really is

;;;;;;;;;;;;;;;;;;;;
 Fifth line - indicates the rate card data being created as it matches the headers from line 3
rate1;1rate;active;en_GB-pl_PL,en_GB-ar_AA,en_GB-zh_CN;other;Actual price;per word;;2;2;;;;;eur;;;;;

Sixth line -  headers for this part of the rate card
7th and 8th line -  indicate the data per step. I have marked Translate which would be Line 7.
