What causes this issue?

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

System Response

To be able to use <LS>online payment updates</> and <LS>tax updates</>,
you need to have implemented new General Ledger Accounting as well as
set up document splitting accordingly in Customizing under <LS>Financial
Accounting (New)</> -> <LS>General Ledger Accounting (New)</> -> <LS>
Business Transactions</> -> <LS>Document Splitting</>. You can use the
standard splitting procedure 0000000012 here as the basis. Documents
must be split according to the Financial Accounting reference of the
accounting and payment document in the Funds Management document.
For this, you need, for example, the following document splitting
characteristics:
FI document number (KNBELNR)
Payment document number (VOBELNR)
Commitment item (FIPOS)
When activating online payment updates, the system automatically defines
these document splitting characteristics in Customizing for <LS>General
Ledger Accounting (New)</> under <LS>Business Transactions</> -> <LS>
Document Splitting</> -> <LS>Define Technical Document Splitting
Characteristics</>.
For more information, go to Customizing for <LS>Funds Management
Government</> and see the documentation on the activity
<DS:SIMG.SIMG_FM_FMPU_MIGACT>Activate Online Payment Update</>.
Depending on your business requirements, you may need to add document
splitting characteristics.
When implementing the document splitting characteristic FIPOS, note the
following:
Using this characteristic changes how the document is displayed in the
entry view (tax items).
It also affects the general ledger view. In particular when document
splitting characteristics are activated subsequently, it is essential to
test the results very carefully.

How to fix this error?

If you do not want to activate these document splitting characteristics,
seek further advice from Development Support at SAP. Otherwise, you can
change the type of this message in table T100C.
