How can I overwrite the Last Changed Field (AUFK-AENAM)

Question

We have an XI application that updates networks in R3 by calling BAPI_NETWORK_MAINTAIN.   The XI RFC Client Parameter has logon user/password that connects to R3, so when a network header is updated by calling the BAPI_NETWORK_MAINTAIN.....then the logon user id is used to populate AUFK-AENAM.   Is there a way to populate AUFK-AENAM if it was passed to a function/class (or via an EXIT or BADI)........basically I'm looking for a way override AUFK-AENAM.
Thank you any help.

Badi:WORKORDER_UPDATE
Method:IN_UPDATE
Parameter:IT_HEADER_OLD
Set value VBKZ = 'U'"For Update.
Below is SAP documentation of method IN_UPDATE fron SE18:
Functionality
This method is executed during the update after the order is saved.
Parameters
All tables relevant to orders of all the orders processed within this transaction (also cross order type) are transferred. A table containing all changed records is transferred for each order object and a table *_old that contains the original state of the changed records when the transaction was started.
To differentiate between different order categories, evaluate the "AUTYP" field in the order headers.
To determine which actions were carried out on the individual objects of an order, you can evaluate the update indicator in the individual tables. In the different tables, the update indicator is called "VBKZ" (exceptions: IT_PMPARTNER-UPDKZ, IT_PRT_ALLOCATION-MODKZ, IT_MILESTONE-VBKZ_MLST or IT_MILESTONE-VBKZ_MLTX) and can contain the following entries:
"I": Insert
The data record is written to the database again. No *_old entry exists
"U": Update
The data record already exists in the database and has been changed in the transaction. An *_old entry exists.
"D": Delete
The data record already exists in the database and is to be deleted. An *_old entry exists.
The data record exists in the database. No changes have been made in the transaction. An *_old entry exists.
