xRec and FIELDNO

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.

User-Defined Function

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).

Triggers

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