Now after setup and make integration sap business one and customer check out, the articles don't accept any synchronization and don't appear and now due to us localization of our sap the tax rate type appeared for me as an error for integration of articles I can't know the place of putting the tax for each item.
With our standard CCO scenario packages we're fetching the content from OITM field VatGourpSa.
In some B1 localizations (US probably being the most prominent one) no tax code is assigned to the item master data. As a result the field VatGourpSa is empty.
And this explains the tax rate type code missing error in the item synchronization.
There are a few ways to overcome that:
Solution 1) Update the VatGourpSa field directly in the B1 database. But this is probably the least favorable because any newly created item in B1 will have the same issue again.
Solution 2) A more elegant way can be developing partner extensions. Then we need to define a logic for the tag <SalesTaxCode> which is the technical name in our standard packages.
Solution 2a) If in your use case there are only two tax codes (like zero and non-zero or full and reduced tax) then the VATLiable field (on the UI it shows as Tax Liable) can be used with this simple logic.
We already provide an example in our demo scenarios which you can download from the PartnerEdge -> Developer Resources -> Several Example Plug-In for Demo Purpose. You can use the partner step called CCO.MaterialTaxCode and add it to extension point FetchMaterialList_Output
You also have to adjust the partner step so that it knows which tax code to assign in case an item has Tax Liable = Yes / No. If you think a step-by-step description is helpful please let me know and I could write a separate blog on that.
Solution 2b) If in your use case there are more than two tax codes then you could make use of a UDF in the Item Master Data with a drop-down list containing valid tax codes. In this case you can take over the idea of the example that we describe in PartnerEdge -> Developer Resources -> Step-by-Step Guide for One Use Case: Use Case: Fetch User Defined Fields Colour and Size for Materials in SAP Customer Checkout. Also for this case we already have a demo example step called CCO.ExtendMaterial:
Again, if a step-by-step description is helpful for this use case please let me know.
are the Tax codes configured the same in CCO and Business One?
