How to report VAT by Legal Establishment?

Hi,

I hope you can help. We have an enterprise model in a Danish company consisting of a single ledger and two legal entities, each with an operating unit.

Each LE has a separate VAT Registration Number.

One of the LE has in addition a number of establishments associated, each with their own VAT Registration Number.

My question is, how do I process and report on the VAT separately for these establishments?

For example, when I process an AR invoice and apply the VAT, how do I ensure that it is reported for under a particular establishment?

Should I use a determining factor such as Line Account, where for examle the balancing segment value indicates the establishment? But what to do if there are multiple balancing segments on a single trx?
