Open the 
Date Compress Bank Acc. Ledger window.
Compresses or combines bank account ledger entries so that they take up less space in the database. You can compress entries from closed fiscal years only.
The compression works by combining several old entries into one new entry. For example, bank account ledger 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 to the entry 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 preceding fiscal year.
After the compression, with the Retain Field Contents facility, you can retain the contents of the Document No., Our Contact, Global Dimension 1 Code, and Global Dimension 2 Code fields.
The number of entries that result from a Date Compress Bank Acc. Ledger batch job depends on how many filters you set, which fields are combined, and which period length 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. The Options FastTab contains fields in which you must specify conditions for running the batch job.
 Warning |
|---|
| Date compression deletes entries, so you should always make a backup copy of the database before you run the batch job. |
Options
| Field | Description |
|---|---|
Starting Date | Enter the first date to be included in the date compression. The compression affects all bank account ledger entries from this date to the Ending Date. |
Ending Date | Enter the last date to be included in the date compression. The compression affects all bank account ledger entries from the Starting Date to this date. |
Period Length | Select the length of the period whose entries are combined. To see the options, choose the field. If you selected the period length Quarter, Month, or Week, then only entries with a common accounting period are compressed. |
Posting Description | Enter a text to accompany the entries that result from the compression. The default description is Date Compressed. |
Retain Field Contents | Select if you want to retain the contents of certain fields even though the entries are compressed. The more fields you select, the more detailed the compressed entries are. If you do not select any of these fields, the batch job creates one entry per day, week, or another period, according to the period selected in the Period Length field. |
