Field help (AOEOPTDAT) @ L.V. Expertise X3

This field defines how the date type fields are coded.

You can only specify the order and the number of characters in the year. For the import, any separation characters between fields are filtered. Dates in the DD-MM-YY or DD/MM/YYYY formats are correctly decoded.

The decoding sub-program takes the engine's adxdcs variable into account. This variable is set via the DCS parameter that is found in the general parameters to define how a year is decoded over two characters. DCS represents the pivot year that defines the century change.

For example, if DCS is equal to 1940, any year made up of two numbers:

Less than or equal to 40 is considered to be part of the 21st century
Greater than 40 is considered to be part of the 20th century

It is then possible to express the years between 1940 and 2039 with two numbers.
