Hi, For master data, it is relatively simple, just select the master data table you want to export in Configuration Package, such as Customer, Vendor, Item, G/L Account, and then import it into Compan B. The only thing to note is that the related table needs to be imported first, such as Payment Terms, Posting Group, etc.

For Opening Balance data, this needs to be posted to the database, so the more common practice is to be sorted into Gen. Journal Line (81) first. Then post the lines on the page.

Hope this helps.
Thanks.
