Open the 
Date Compress VAT Entries window.
Compresses VAT entries and combines them so that they take up less space in the database. You can only compress entries from closed fiscal years.
The compression works by combining several old entries into one new entry. For example, VAT entries from previous fiscal years can be compressed so that there is only one credit and one debit entry per account per month. The amount in the new entry is the sum of all the compressed entries. The date assigned is the starting date for the period that is compressed, such as the first day of the month, if the entries are compressed by month. After the compression you can still see the net change for each account in the previous fiscal year.
After the compression the contents of the following fields are always retained: Posting Date, Type, Closed, Gen. Bus. Posting Group, Gen. Prod. Posting Group, VAT Calculation Type, Base, and Amount. With the Retain Field Contents facility, you can also retain the contents of the following additional fields: Document No., Bill-to/Pay-to No., EU 3-Party Trade, Country/Region Code, and Internal Ref. No..
The number of entries that result from a Date Compr. G/L Budget Entries batch job depends on the number of filters that you set, the fields that are combined, and the period length that you choose. There is always at least one entry. When the batch job is finished, you can see the result in the 
Date Compr. Registers window.

| Date compression deletes entries, so you should always make a backup copy of the database before you run the batch job. |
