    Hi Pawan

    It seems you use an external system Taxware to calculate taxes. During invoicing taxes are getting recalculated because of the copy control. But the remote function call to Taxware is not getting executed because the connection is missing or the other system is not responding to calls. Go to SM59 and check for TCP/IP connections. In that find Taxware connection, double click on it and click on check connections. See if the system is responding or not.

    • Hi Pawan,

      Most of the FS 864 errors reported to-date have been related to

      missing customizing. This may not be the case however, be sure to

      check your configuration in the IMG:

      Fin Act>Fin Act Glbl Set>Taxes of S& P> Basic Set> Ext Tax calc>

      Activate External Tax calculation

      For the tax procedure referenced, please be sure to check that the

      logical destination is set to "VERTEX".

      Please also refer to note -> 392696 R/3 Tax Interface Configuration

    You need to check in the following IMG path

    Cross Application Components > SAP Business Partner > Basic Settings > Tax Jurisdictions > Using Non-SAP Tax Software

    Here you have to ensure that the required RFC destination is created and assigned to the destination country.

    Obviously, this is Basis team's job
