SYSTEM.MASTER_BLOCK system variable<br />

Syntax<br />

SYSTEM.MASTER_BLOCK<br />

Description<br />

This system variable works with its companion SYSTEM.COORDINATION_OPERATION to help an<br />

On-Clear-Details trigger determine what type of coordination-causing operation fired the trigger, and on<br />

which master block of a master/detail relation.<br />

The values of the two system variables remain constant throughout the clearing phase of any block<br />

synchronization. SYSTEM.MASTER_BLOCK represents the name of the driving master block, and<br />

SYSTEM_COORDINATION_OPERATION represents the coordination-causing event that occurred on<br />

the master block.<br />

Please see the reference topic for SYSTEM.COORDINATION_OPERATION for more information.<br />
