Diagnosis
There must not be any gaps in the assortment declaration history. If agap has occurred as the result of an incorrect deletion or a directdeletion in the database, all declarations in the period after the gapmust be canceled. The next declaration must then begin with the startdate of the period containing gaps. It is not possible only to declarethe period with gaps since the subsequent declarations should not existat all on account of the gap.
The described situation is an exception.

Procedure
The following example illustrates how to proceed.
The following declarations exist:
01.01.2001 to 31.03.2001, 01.04.2001 to 30.06.2001,
01.07.2001 to 30.09.2001 and 01.01.2002 to 31.03.2002
A gap occurred from 01.10.2001 to 31.12.2001. Consequently, alldeclarations subsequent to 31.12.2001 should be canceled.
