Message text: Clearing lock &1 set in document &2
The clearing lock &V1& has been set for all document items of document
&V2&.
A special case has occurred during creation of the aggregated incoming
bill which means that the posted uncleared FI-CA document must be
checked before clearing takes place. Therefore, the clearing lock &V1&
has been set for all document items of document &V2&.
Check, for example, whether a special case exists where a tax correction
posting takes place that only requires a correction to the tax amount.
With this combination of data, the situation can arise that the paid
budget billing payments exactly match the bill amount, but there is a
minor difference (due to rounding difficulties) between the individual
posted budget billing bills and the posted bill amount in the total.
However, the combination of data result in major differences and you may
no longer be able to remove the clearing lock because the document item
has already cleared itself (self-clearing due to zero amount).
Check document &V2&. If you do not find any errors, and self-clearing
has not occurred, use transaction FPE2 (Change Document) to remove the
clearing lock &V1& for all document items that have not cleared
themselves.
Self-clearing is only permitted if the maximum limit (&V3&) is not
exceeded for the following special cases:
Gross amount equal to tax base amount equal to zero, but tax amount not
equal to zero
Tax base amount and tax amount have different +/- signs
Gross amount and tax amount not equal to zero, but tax base amount equal
to zero
If an error occurs, contact your system administrator.
In the event of an error, and based on the correction or release status
of your system, you can use a report to reverse the document for the
aggregated incoming bill. To do this, create a problem message.
