You use this function to reverse or invert many documents, which have been posted either manually or automatically.

The system features two modes for reversing documents:

• Reversal
• Inversion

Reversal mode reverses already-posted documents by posting a second document, which posts the same set of characteristics but with reversed debit/credit signs. The reversal does not produce a remaining net difference.

The reversal document posts in the same period in which the reversed document was posted.

Neither the reversed document nor the reversal document can be reversed themselves.

Inversion mode reverses postings that were made in earlier posting periods. Thus, an inversion is not a true reversal because a net difference remains in the original period (of the inverted document):

It is still possible to reverse a document that has been inverted. When an inverted document is reversed, the inverting document is also reversed with the result that a remaining net difference no longer exists in both the period of the inverted document and the period of the inverting document.

See also the example below.

The system uses the following selection criteria to determine which documents are to be reversed or inverted:

Furthermore, for an inversion you can select whether to reverse the following documents:

• Pairs of reversing and reversed documents
• Reversal (reversing) documents
• Reversed documents

You also select the fiscal year and period in which the mass reversal is to be posted. These are called:

• Reversal year
• Reversal period

After you specify the selection criteria and start the mass reversal, the system displays a list of documents that match your criteria. You then select the individual documents to be reversed or inverted.

• The tab page Documents to be Reversed lists all documents which match your criteria and can indeed be reversed (mode R) or inverted (mode I).
• The tab page Irreversible Documents lists the documents that cannot be reversed or inverted.

5. In the list of documents to be reversed, select the individual documents to be reversed or inverted.
6. Choose Save to start the mass reversal.
7. On tab page Processed Documents the system displays another list of the actually reversed or inverted documents.
8. If applicable, repeat steps 5 and 6.

Neither is possible.

Both documents (number 1 and 2) are reversed. This is done even if you only select one of the two documents in the list of documents to be reversed or inverted.

Thus, if the list only contains document number 1, both documents are reversed.

However, if the list only contains document number 2, this document can neither be reversed nor inverted.

Neither is possible.

This is not possible.
