T-SQL (SS2K8) :: Item Sales Batch Allocation

I found next script for batch item allocation based on FEFO/FIFO method (according to DateCol interpretation) :

DECLARE @Table TABLE
(
RowID int identity Primary Key,
DOCTYPE varchar(40),
DateCol datetime,

[Code] ....

The result looks like :

RowIDDOCTYPEDateCol QTYPRDLOT
1 Purchase2007-01-01 00:00:00.0000AA2007FW
2 Sale 2007-01-03 00:00:00.000-30AA2007FW!2007SS
3 Purchase2007-01-04 00:00:00.00020AA2007SS
4 Sale 2007-01-04 00:00:00.000-20AA2007SS
5 Purchase2007-01-09 00:00:00.00010AA2007FW

The issue is on the second line. What I need is to split that record in 2 or more lines, every line containing one single lot record.
