Hello,
are these steps done ?

Creating an Archive Company
Number of archive companies
When you set up an archive company, various concepts and strategies are involved.
You can have one archive company, which will be fed with data yearly, that is, the
operational company will archive its data each year to the same archive company.
Therefore, all data will be centrally stored. However, this concept has one
major drawback: performance degradation.
Due to the transfer of large amounts of data from the operational company
to the archive company, over time, the archive company grows larger than the
operational company. Therefore, you must make enough disk space
available, which, in turn, significantly decreases the performance of the
archive company as more data is archived.

The second concept of setting up an archive company implies the data
of the operational company will be archived each year to
a new archive company. Having one archive company for each archiving
period limits the size of the archive company, which, in turn, stabilizes
the performance to access this data. You can easily store this archive
company onto an external device for a longer period of time. At the end
of the archiving cycle the data will be cleared. With one archive company
for each year, you can easily drop the entire company at
once, whereas filtering the old data that can be removed from one
large archive involves more investigation and takes more time.

Another point worth considering setting up the archive company is the
strategy towards migration. If the operational company will be migrated
in the future, the archive company must also be migrated. With this strategy, it is
easier to migrate multiple smaller companies than one large archive company.

When you archive in LN, you must keep close watch on the company numbers (operational – archive).

Note
The subsequent procedure for creating an archive company is valid for a standard, non-localized and non-customized ERP environment.
In the examples used throughout this document, companies 001 and 002 are operational companies; companies 901 and 902 are archive companies.
To perform the steps to create an archive company, you must be super user.

Thank you for your information.

Yes , the archive company set up done. I can archive Production order, Warehouse order. Sales order and purchase order just archive some history data to archive company. but tdsls400,tdsls401,tdpur400,tdpur401 don't have any orders archive to archive company.

"Archive/Delete Sales Order/Schedule History" (tdsls5201m000) just deletes the sales order history data at LN FP7 version. Sales order and Sales order line can't archive any data at LN FP7 version . Who can help me confirm is right or not? Thanks
