ValidTimeStateFieldType Property on Table- AX 2012 R2, R3

What is the use of “ValidTimeStateFieldType” property on table

Date effective data is tracked in a table that has its ValidTimeStateFieldType changed from its default value of None. Also, an index with its ValidTimeStateKey set to Yes must be added on the table. The system automatically adds the fields named ValidFrom and ValidTo to the table, which will be of type date or utcdatetime. The system automatically prevents overlap between the date ranges in these two fields among rows that track the same entity.

How to fetch records from this type of tables

The following code sample returns the records that are effective during 1/1/2001 and Current date:

static void theAxapta_ValidTimeState (Args _args)

{

vendTable vendTable;

TaxRegistration TaxRegistration;

DirPartyLocation DirPartyLocation;

date ToDate = today();

date FromDate = 01\01\2001;

while select validtimestate(fromdate, ToDate) * from TaxRegistration

join DirPartyLocation

where TaxRegistration.DirPartyLocation == DirPartyLocation.RecId

{

select vendTable where vendTable.Party == DirPartyLocation.Party;

info(strfmt(“%1”, VendTable.Name));

}

}
