Changing Prenotes 
Use
Most prenotes are automatically changed with the Business Application Programming Interface (BAPI) for the creation of prenotes: Prenote.ChangeMultiple. For more information, see the BAPI documentation.
If you have used a PLM document to create a prenote in Posting Lock Management (FS-AM-PLM) you can change it in Posting Lock Management only. For more information, see: Editing Prenotes.
However, you can also change prenotes online if they were created online or by means of a BAPI. This process is described below.
You can make changes online or by using a BAPI, but only on the expiry date and to the long and short text of the prenote.
To change the amount of a prenote, delete the prenote and create a new one with the required amount.
Prerequisites
You need to create the prenote either online or by means of a BAPI, and the prenote must have the Active status.
To use the 
framework for the
principle of dual control when you change prenotes, then you need to
process the following IMG activities in the Customizing for Account
Management (FS-AM) under Item Management -> Prenote ->
Release:
- Assign Release Object to Release Procedure
- Assign Rule to Release Steps
- Assign Release WF and Release Procedure WF to Release Procedures
Procedure
...
1. From the SAP Easy Access screen, choose Account Management ® Account ® Turnovers, Balances and Key Figures ® Prenote ® Change Prenote. The system displays the Prenote Change initial screen.
2. In the Account group box, enter the identification of the account to which the prenote is assigned that you want to change.
3. Specify the prenote reference number of the prenote to be changed, then choose Continue. The system displays the Prenote Change main screen.
The main screen is structured as follows:
¡ The Account and Prenote group boxes are in the upper screen area:
The system displays the account identification and the prenote reference number that you specified on the initial screen, and the prenote type and prenote status.
¡ The Detail Data tab page:
The system displays all additional data that you entered when you created the prenote (see Creating Prenotes). In addition, the system displays the posting date when you create the prenote, and it also displays the Valid To date (expiry date) and expiry date of the prenote.
¡ The Administration tab page:
§ The Checks Deactivated By group box shows whether material checkswere deactivated, and thus not run when you created the prenote.
§ The Administrative Data group box shows when the prenote was created, who created it, if it was changed, and whether it was created online or with a BAPI.
§ The Archiving group box shows when the system archives the prenote after it is deleted if it can be archived according to your settings in the Customizing for Account Management (FS-AM) under Item Management ® Prenote ® Define Prenote Type.
4. On the Detail Data tab page, you can change the Valid To date (expiry date) of the prenote in the Date Specifications group box.
Note that the expiry date must not be before the current posting date. If you do not specify an expiry date, Account Management calculates one using the corresponding value date conditions that you stored in the account for the relevant prenote type. If you have not defined a suitable value date condition, the system generates an error message. You need to correct the formal error before you can create the prenote.
5. You can change the long and short texts of the prenote in the Texts group box, but any other changes are not possible.
6. Save your entries.
Result
After you have saved your entries, the prenote undergoes a series of formal checks (see Formal and Material Checks for Prenotes). If the checks do not find any errors, the prenote either receives the status Active or completes the relevant release procedure (for example, the principle of dual control) depending on the Customizing for Account Management (FS-AM) under Item Management ® Prenotes ® Release ® Assign Release Object to Release Procedure.
While the release procedure is being completed, the previous prenote retains the status Active so it is ready for any possible matches. Another prenote is created in parallel with the status To Be Changed. As soon as the release is completed, the active prenote is overwritten with the new data and given the Active status. The prenote with the To Be Changed status is physically deleted from the database.
