Regular Sage 100 doesn't have that for SO tables, but DSD's enhancement SOAT is worth considering.

Thanks much for quick response... your a great resource.. 

In Sales Order currently all it records is who created the order and the last person to update the order. 

Created a simple Sage Intelligence report with no filters using the ABC Co. pulling the SO Number, Date,Status, User Code, Name, User Created and Updated dates.

I haven't had a chance to create a report in SI.. so I tried exporting from SQL and there is no common field between SO header or detail tables and SYS_USER so not sure how you brought user into report.. 

Sure there is, User Code, it's the second field in SY_User same as UserCode in the Sales Order Header, one of the last fields.

It's actually user key fields in SO header, which can be translated into user codes / names by linking to SY_User (twice).

This doesn't tell you what changed though.  For details, you need something more, like a custom change report using software like ActionQ / SA&WF, or the DSD enhancement.

Yep that is all I see are the key fields and I know this wont give them what they want but might be enough figured it can't hurt to show them.  I did check into the DSD - SOAT you mentioned and doesn't seem to costly.. 

I actually created 2 sub-reports one to pull the UserCreated and one for UserUpdated info

Here's the link for the User Created report:

("SO_SalesOrderHistoryHeader"
INNER JOIN "SY_User"
  ON "SO_SalesOrderHistoryHeader"."UserCreatedKey" = "SY_User"."UserKey")

The User Updated report:

("SO_SalesOrderHistoryHeader"
INNER JOIN "SY_User"
  ON "SO_SalesOrderHistoryHeader"."UserUpdatedKey" = "SY_User"."UserKey")

Referring to the sub-reports, is this the screenshot you gave from SI? Or did you create this in SQL?  Is there a way to capture what change was made, or the DSD solution is the easiest way to solve that?
