Hi Raja,
We have many FF805 errors reported by customers and the same solution
has resolved the problem. Please note that the SD-FI interface changed
from earlier releases.
In the vast majority of cases, error FF805 occurs because of an error
in your pricing procedure. The previously attached note 112609 explains
in detail how tax codes are transfered to conditions.
The note 400766 explains the checks performed by the system on the Tax
codes:
1. system checks whether there is a revenue line for each tax line.
2. in the reverse case, for each revenue line containing a certain
   tax indicator there must be a tax line with this indicator.
If the tax condition has condition value zero and condition base
value zero, then it is not transferred to FI.
If you have revenue lines containing a tax indicator XX, but no
tax line with tax indicator XX, then the error FF805 issues, and
it is justified. => Please check these informations. I have attached
notes for further information.
-> EXAMPLE
   If tax condition MWST has base amount zero and value zero; for this
   reason it is not passed to accounting. But, according to the
   criteria reported by note 112609, its tax indicator EG: A7
   has been assigned to the condition EG: ZBR1.
   So in accounting there would be a revenue line with tax indicator A7,
   but there isn't any tax line with indicator A7 (because MWST doesn't
   pass to FI). The note 400766 states situation is unallowed, and error
   FF805 is justified.
Thanks and best regards,
