Data Manipulation in Dynamics Ax 2012- Array as Extended Data Type

I found a array based field in TSTimesheetLineWeek table, Field TSWeeklyHours

Now challenge is to enabled field based on Array. For example need to disabled on day 6.

Following code snippet help me to enabled disabled fields generated on the base of array extended Type

TSTimesheetLineWeek_ds.object(fieldId2Ext(fieldNum(TSTimesheetLineWeek, Hours), 6)).allowEdit(false);
