Example
The following example opens table 37, the Sales Line table, as a RecordRef variable and creates a reference to field 2 (Sell-to Customer No.). The FieldRef Data Type of field 2 is stored in the MyFieldRef variable. The RELATION function retrieves the number of the table that has a relation with the Sell-To-Customer field (field 2). The table number is stored the varRelation variable and displayed in the message box. This example requires that you create the following variables and text constant in the C/AL Globals windows.
| Variable name | DataType |
|---|---|
SaleRecref |
RecordRef |
MyFieldRef |
FieldRef |
varRelation |
Integer |
| Text constant | ENU value |
|---|---|
Text000 |

SaleRecref.OPEN(37);
MyFieldRef := SaleRecref.FIELD(2);
varRelation := MyFieldRef.RELATION;
