SAP Error Message - Details

• Message type: E = Error

• Message class: MN - Message class for subsequent settlement (Purchasing)

• Message number: 817

• Message text: You are updating the "actual" data (see long text)

What causes this issue?

Version '000' contains the data updated from dialog mode (goods
receiving, invoice verification). This will be changed through the
updating of the external supplier business volume data without there
being any relevant ordering or invoice verification documents.
Under certain circumstances, this can have serious consequences.

System Response

If you respond to the confirmation prompt with "Yes", the program will
be run.

How to fix this error?

Please check that you really wish to change the actual data for version
'000'.
You can adopt one of the following approaches:

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

You can, of course, update the data directly in version '000'. However,
since - despite all precautionary measures - errors with grave
consequences may occur when you do this, take care to do the following:
Be sure to carry out a test run.
If necessary, create a backup copy of version '000'.
Take suitable organizational measures to ensure that the data transfer
is carried out properly (import file once only, consistency of supplier
business volume data, etc.).
At all events, archive the external files so that these are available in
the event of any necessary recompilation.
If supplier business volume data is updated both in dialog mode as well
as via external data transfer, in the case of a new compilation of the
supplier business volume from purchasing documents or a new compilation
for a subsequently entered rebate arrangement, all affected external
data files must also be imported.
Please note that the function "Detailed statement: purchasing documents"
only covers the supplier business volume stemming from purchasing
documents (that is to say that there will be differences between this
and the statistical data).
Initially, you can compile the supplier business volume data (for test
purposes or in the first transfer of old/historic data) under a version
number beginning with the characters '&('. You can specify the third
character yourself. Following successful compilation, the data can be
recopied into version '000' using report 'RMCVISCP'.
If data already exists, you can first create a copy of the data (e.g.
under the version number '&(1'), then carry out the updating of the
external data under the version number '&(1', then check the data, and
finally copy the latter into the version number '000' (Report RMCVISCP).
