Here is the General Tab of Avatax Settings Below you can find a description of each option.

Send Freigths as Line Items: With this checkbox marked you'll be charging taxes over your freigths. Here is an example of how you'll see it in SAP and in Avalara.

Send freight line as discounted: By checking this option, when sending freight lines as items lines to Avatax, the lines are considered to apply discounts. Therefore, If this option is checked, when applying a document header level discount in SAP, the discount is distributed by Avatax on all document lines that have the discounted flag. On the other hand, if this setting is unchecked, will make the SAP document header discount not applied by Avatax to the freight lines.

Use document first line ship-to as freight ship-to: The default behavior is to use the document Ship-to address as the ship-to address for document freights. But, if you need to use the first document line ship-to address as the ship-to address for document freights, checking this option will allow you to use a different ship-to address for the freights by using the options provided at the document line: Line, Branch or Warehouse Ship-to Address.

Do not send item tax codes: By checking this option, the information contained in the "Avatax tax code" UDF won´t be included in the document. However, if you have your items mapped into your Avalara console with Avalara tax codes assigned, the tax code will applied even though this option is checked. 

Save and Split tax info on document lines: With this checkbox marked you'll be able to see how much taxes are being charged per item. Here is an example.

Log Request: With this checkbox marked the addon will save a log entry in the UDT (User Defined Table) for your transactions. This log can be used to check for issues. We recommend having this option checked

BP Field for Customer Code: With this dropdown list you can (instead of the default CardCode as customer's code) send CardName or Email, this would be helpful if you already have customers and/or certificates uploaded in Avalara and you start using SAP or vice versa.

Item Field for Item Code: The default field from OITM to be used is ItemCode, but other fields can be used. This is useful if you already have defined items in the Avalara portal and don’t want to use your SAP Item Codes to report the documents.

Tax Only Item Code: This field can be used to create a Tax Only Document and avoid the recalculation. Here is an example.

Item Price: This option allows you to select the default source of price for your items, either the price you assign at the document level or from one of SAP native lists. Anyway, you'll be able to change it on each document as shown below.

Tax code for Avatax calculation: Here is where "Avatax" as a tax code is defined indicating that every time you create a marketing document where at least one line has this tax code, the addon will execute and send the document to Avalara for its calculation. (Check How AvaTax Works)

Tax calculation on Reconcile Window and Event Service: Due to a SAP limitation, marketing documents such as:

A/R Invoice and Credit Memo, can't be modified once created. So in the case you need to use the Reconcile Window or you have the Event Service, you can defined here how you'll see the taxes in those documents.

Add Taxes to UDF: With this checkbox marked, if you use the Reconcile Window, you'll see the Invoice as follows

Add Journal Entry: With this checkbox marked you'll have to define in which Tax Account, the taxes calculated by using the Reconcile, will apply
