AX 2012 Disable/ByPass extensible data security (XDS) through code

Extensible Data Security or XDS is a framework introduced in AX 2012 to apply security on data. We had RLS or Record Level Security in AX 2009. However, XDS is completely a new framework with more capabilities in order to apply data security. This post is about disabling or bypassing the XDS using code. For more details about XDS, download a whitepaper provided by Microsoft using following link.

Disabling/Bypassing XDS or Extensible Data Security:

Recently, I had a requirement to restrict users from viewing all the Warehouses available and they must be able to see only the Warehouses they belong to. I designed a new security policy and it started working very easily without much problem. However, the problem was on Inventory Transfer From where we have two fields for Warehouses:

1. From warehouse and
2. To warehouse

Our requirement was to restrict only From warehouse and To warehouse MUST show all the warehouses available so they can issue inventory to any warehouse but should not be allowed to issue inventory from the warehouse they don't belong to. In order to achieve this, I had to disable the XDS on To Warehouse lookup method. I did override the lookup() method on To Warehouse field on the datasource and below is the code which I wrote to disable the XDS.

public void lookup(FormControl _formControl, str _filterStr)

{

    XDSServices                      xXDS = new XDSServices();

    xXDS.setXDSState(0); // Disable XDS

    super(_formControl, _filterStr);

    xXDS.setXDSState(1); // Enable XDS

}
