Deferred tax: Ref. clearing doc. not yet posted (CC &1, FY &2, Doc. &3)

What causes this issue?

During processing of a transfer document for deferred taxes, the
referenced clearing document was not found.
This is usually a temporary problem caused by the sequence in which
documents are processed. Either the processing of the tax transfer
document was started before the referenced clearing document was posted
or reprocessing of the referenced clearing document using the function
?Central Reversal with Reposting? was incomplete or the processing of
the packages in the initial load did not occur in the correct sequence.

System Response

If this message was raised during ongoing replication, the AIF message
has to wait for the referenced clearing document to be posted (or
reposted).
If this message was raised during the initial load, an error is
displayed in the error log for the corresponding package.

How to fix this error?

For ongoing replication, restart the AIF message once the referenced
clearing document has been posted (or reposted).
For the initial load, the run must be repeated until the error
disappears.
