xRec and FIELDNO

Microsoft Dynamics NAV 2013

When a user-defined function or a trigger is executed on a table object, xRec and FIELDNO are set differently, depending on how the function or trigger is executed. The following tables explain what happens in the different scenarios.

The following table explains what happens to xRec and FIELDNO when a user-defined function on a table object is called from either external or internal C/AL code. External C/AL code means that the calling code is in a different object. Internal C/AL code means that the calling code is in the same object (another function in the same object).
