When a user-defined function or a trigger is executed on a table object, xRec and CurrFieldNo 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 CurrFieldNo 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).
| Execution initiated by | xRec value | CurrFieldNo value |
|---|---|---|
External C/AL code | Empty | 0 |
Internal C/AL code | Unchanged | Unchanged |
Triggers
The following table explains what happens to xRec and CurrFieldNo 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. Internal C/AL code means that the calling code is in the same object (another function in the same object).
| Scenario | xRec value | CurrFieldNo Value |
|---|---|---|
VALIDATE trigger called by external C/AL code that calls the VALIDATE function | Copy of Rec before assignment in VALIDATE trigger | Field number of field being validated |
VALIDATE trigger called by internal C/AL code that calls the VALIDATE function | Unchanged | Unchanged |
Any table or function called by C/AL that initiates a call to a trigger other than VALIDATE | Copy of Rec before trigger is executed | 0 |
