DMSII Dates Represented as a GROUP of Numbers

The DMSII GROUP must always contain a year and a month; the day can be omitted, in which case it defaults to 1. To clone a DMSII date (represented as a group of numbers) as a relational database date, write a user script (script.user_layout.primary_tablename) that does the following:

1. Sets the DIOPT_Clone_as_Date (2) bit in the di_options column
2. Sets the dms_subtype column of the group members in DMS_ITEMS to indicate which part of the date they represent, as follows:

   Part of Date in GROUP	Value for dms_subtype Column
   Year (assumes a 1900 base)	1
   Month	2
   Day	3
   Year By default, yy values < 50 are 21st century years (20yy) and yy values > 50 are 20th century years (19yy).*	4
   Absolute year This is a 4-digit year specification (for example, 2010).	5

*The following SQL statements cause the DATABridge Client to clone the DMSII group INV_DATE as a relational database date type.
