*RePost* Copy Data

[John]

I have a database that tracks transactions for internal
comany use (intrabank transfers, wire transfers, etc.).
Many of these entries are similar period to period
(changing only in amount and maybe description).

I would like to take a given period's transactions and
detail and copy to a new period. This will allow me to
minimize the overall amount of work in entering in a new
period's transactions.

I know how to do this with two related tables (as below,
tblPeriod/tblTransHeader or tblTransHeader/tblTransDetail)
but how do you do it with three related tables.

The procedure will create a new period record and then
copy the prior periods transactions headers and related
details. I have prety much everything worked out, except
for the query(SQL) to append the old records to their
tables using the new related values.

The table structures is as follows (not all tables, just
the ones that apply to my issue).
tblPeriod
PeriodID
...
tblTransHeader
TransHdrID
PeriodID
TransDescription
...
tblTransDetail
TransDetID
TransHdrID
AcctNumID
...

A sample of the data BEFORE copy (assumming only one
period), simplified.
tblPeriod
200404 . . .
tblTransHeader
1 200404 Intercompany . . .
2 200404 MM Transfer . . .
tblTransDetail
1 1 12345 . . .
2 1 22345 . . .
3 2 10010 . . .
4 2 10025 . . .
5 2 10026 . . .
