Date Compression

2023/12/13 • 3 min. to read
You can compress data in Business Central to save space in the database, which in Business Central online can even save you money. The compression is based on dates and works by combining several old entries into one new entry. You can compress Cost Entries and Cost Budget Entries under the following conditions:
  • They're from closed fiscal years.
  • The Open field is set to No. (Cost Entries)
  • They're at least five years old.
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. The number of entries that result from a date compression depends on how many filters you set, which fields are combined, and which period length you choose. There will always be at least one entry. When the batch job is finished, you can see the result in the Date Compr. Registers page. When you are defining criteria for the compression, you can use the options under Retain Field Contents to keep the contents of certain fields. After the compression, the contents of the following fields are always retained:
  • Posting Date (Cost Entries)
  • Budget Name (Cost Budget Entries)
  • Date (Cost Budget Entries)
  • Cost Type
  • Cost Dimension (1 to 8)
  • Posting Type
  • Source Type
  • Work Type Code
  • Unit of Measure Code
Date compression creates new entries for the compressed entries.


For Cost Entries applies:
  • The assignment of the G/L entries and the FA entries in the cost entries is not lost during date compression, but points to the new cost entries after compression.
  • It is not possible to reverse the date compression itself. If you reverse the entries created by date compression anyway, the compressed entries are treated as normal entries and will be reversed.


The Date compression deletes entries. We recommend that you create a backup of the database before you run the batch job.

To run a date compression

  1. Enter Data Administration in the search, and then choose the related link.
