RENAME Function (Record)

  • Article

Changes the value of a primary key in a table.

[Ok :=] Record.RENAME(Value1[, Value2,...])

Parameters

  • Record
    Type: Record The record that contains the primary key that you want to change.
  • Value1, Value2, …
    Type: Text The new values for the primary key.

Property Value/Return Value

Type: Boolean

true if the primary key was renamed; otherwise, false. If the record does not exist or if you do not have permission to write to the table, then false is returned.

If you omit this optional return value and if the record is not renamed, then a run-time error occurs. If you include the return value, then you must handle any errors.

Remarks

For example, you can use the RENAME function if you use the customer's telephone number as the customer number. You can use this function to change the customer number if the telephone number changes.

You cannot rename some tables. Examples of the types of tables that you cannot rename are as follows:

  • Tables in which the user cannot rename the Document No. field for legal or business reasons.

  • Tables in which an Option data type field, such as Document Type, is part of the primary key.

Some examples of tables that you cannot rename are as follows:

  • Table 36, Sales Header

  • Table 38, Purchase Header

  • Table 5405, Production Order

  • Table 5766, Warehouse Activity Header

    If an end-user modifies a record between the time that another end-user or another process reads the record and modifies it, then the second user must refresh the value of the record variable before editing the record. Otherwise, the end-user receives the following run-time error:

    Another user has modified the record for this <Table Name> after you retrieved it from the database.

    Enter your changes again in the updated window, or start the interrupted activity again.

    In earlier versions of Microsoft Dynamics NAV, certain situations allowed code that an end-user runs to modify a record after a newer version of the record was written and committed to the database. This would overwrite the newer changes. However, in Microsoft Dynamics NAV 2013 R2, we have restricted the MODIFY Function (Record), RENAME Function (Record), and DELETE Function (Record) so that the end-user retrieves the following run-time error in these certain situations:

    Unable to change an earlier version of the <Table Name> record. The record should be read from the database again. This is a programming error.

    You must design your application so that you use the most up-to-date version of the record for modifications to the database. You use the GET Function (Record) to refresh the record with the latest version. The second example illustrates this situation.

Example

This example requires that you create the following variable in the C/AL Globals window.

Variable name DataType Subtype

ItemRec

Record

Item

 
ItemRec.GET(‘1150’);
ItemRec.RENAME(‘1105’);

Example

This example shows that you get an error if you attempt to rename a record after a newer version of the record has been written and committed to the database. This example requires that you create the following variables in the C/AL Globals window.

Variable name DataType Subtype

CustomerRec1

Record

Customer

CustomerRec2

Record

Customer

In this example, you get a copy of a record from the Customer table and put it into the CustomerRec1 variable, then you modify the record. Next, you get a copy of the same record from the Customer table and put it into the CustomerRec2 variable. You modify the record and commit the changes to the database. Now the CustomerRec1 variable is out of date with the value in the database. If you were allowed to modify the record using the CustomerRec1 record, then the changes that you made with CustomerRec2 would be overwritten by the values in the CustomerRec1 variable. Microsoft Dynamics NAV 2013 R2 does not allow you to rename a record with the old version of the record.

Note

If you do not call the COMMIT function in this example, then you do not receive an error.

CustomerRec1.LOCKTABLE;
CustomerRec1.GET('10000');
CustomerRec1."Address 2" := 'Suite 101';
CustomerRec1.MODIFY;
CustomerRec2.GET('10000');
CustomerRec2."Phone No.":= '206-555-0109';
CustomerRec2.MODIFY;
COMMIT;
CustomerRec1."Phone No." := '425-555-0184';
CustomerRec1.RENAME('10001');

If you run this code example, then you get the following error:

Unable to change an earlier version of the Customer record. The record should be read from the database again. This is a programming error.

Identification fields and values:

No.='10000'
