Hi Manuel,
There are a few steps for setting up multiple applications databases against a single system database that aren't really publicized although they do NOT violate licensing.
1) In the company table, you need to update two company table fields in order to get your lookup of accounts and subaccounts in the new company. The value they are looking for is the COMPANY ID. The company table is in the System database. Those fields are:
Company.CpnyAcct
Company.CpnySub
2) You need to populate the table [System DB].dbo.
Intercompany.
Use [System Database]
insert into [InterCompany]
SELECT '' as [FromAcct]
,CpnyID as [FromCompany]
,'' as [FromSub]
,'ZZ' as [Module]
,'' as [Screen]
,'' as [ToAcct]
,CpnyID as [ToCompany]
,'' as [ToSub]
,'' as [User1]
,'' as [User2]
,0 as [User3]
,0 as [User4]
,null as [tstamp]
FROM Company
where cpnyid not in (select fromcompany from intercompany
3) Once you add those fields, be sure to "Update Triggers". This is a process used to synchronize the [System Database].dbo.AcctSub, AcctXRef, and AcctSub tables.
4) In Database Maintenance (98.290), run "Synch Selected Database ...." for BOTH of your databases.

These steps should smooth the way in using your new application database.
Please let me know if I can be of further assistance.

Thanks to all for your messages, I think the best option is adding an aplication database to the existem system database, in this mode we do not violate any license restrictions.
Best regards

Hi Gail,
Thank you for your comments y really appreciate,
From what you tell me, could I then add an application database in the same system database and with that it would not violate any license restrictions?
Thanks in advance and i hope your response

It depends on how you want to do multi-company. We do "multi-company" but do not actually own the M/C module.
In our situation, we create a separate database for each additional branch we open, adding it to the existing system database. As long as there is only one system database, we are not violating any license restrictions.
If your need is to have multiple companies within the same database, that's different and you will need to contact a VAR to see what your options might be.
Best regards,

Hi everyone, is there a way to add the multi-company module to my current SL 7 installation? the problem is that I no longer have an active maintenance plan with Microsoft.
