CJ20N User Field Descriptive Text

Question

Hi all,
In CJ20N, for an Activity's User Fields tab, we have a need to add descriptive text next to the field AFVGD-USR03 such that when data is entered into the field, the descriptive text is populated.
For example, we've implemented the field to input a user ID. We would like the user's name to appear to the right of the field as descriptive text.
How can we do this?

First Option -
SPRO - Project System - Structure - Operative Structures - Network - Enhancements for Network - Create Customer-Specific Fields in Network Activities
Create Customer-Specific Fields in Network Activities
The following SAP enhancement is available for networks in the Project System:
CNEX0008    Customer-specific fields in network activities
You can use this enhancement to add new customer-specific fields to network activities in table AFVU. To process these fields you can create your own screen, which the user can call up when maintaining networks. or from the project planning board.
The enhancement CNEX0008 contains the following enhancement components:
Menu entries:
SAPLNWGR+CU1 project planning board
SAPLNWCU+CU1 network maintenance (CN21, CN22, CN23)
Function exits:
EXIT_SAPLCONW_002 for data transfer to your own program
EXIT_SAPLCONW_003 for data transfer from your own program
Screen areas:
SAPLCONW2999_CUSTSCR1_SAPLXCN10800
Activities
1. Create the enhancement.
To do this, either create a new project or use an existing one.
2. Create structure CI_AFVU in ABAP/4-Dictionary (Transaction SE11) in your own development class.
3. Expand structure CI_AFVU to include your own fields.
Please note:
to use the name ranges reserved for customers
the maximum number of fields in database tables, in this case AFVU and CI_AFVU is 749 (for SAP fields and user-defined fields together). For reasons of clarity, we recommend that you keep the actual number of fields to a minimum.
SAP reserves the right to add new fields to table AFVU; if the maximum is reached, your user-defined fields could be removed.
Activate the structure.
4. Maintain the enhancement components:
Assign the function customer fields a name.
Add to the program coding for the function exit EXIT_SAPLCONW_002.  This exit transfers SAP data to your part of the program.
RTo do this, call up the function module and double-click on the include Create the include module.
Add to the program coding for the function exit EXIT_SAPLCONW_003. This function exit takes the data from your part of the program and Ptransfers it to the SAP standard program. Create your own corresponding module.
Create the screen area.
5. Activate the project.
Only once you have activated the project, will your enhancement take effect.
Note for Batch-Input
If you want to fill your customer-specific fields later via batch-input you must take screen SAPLCONW 2999 into consideration.
Second option --
Check enhancement CNEX0001
Overview
  In the standard Project System, the system does not check the
  user-defined fields in WBS elements and activities because their
  significance is customer-specific.
  You can use this enhancement to add a check.  The components of the
  enhancement are each accessed when you make entries in the appropriate
  user-defined field.
Parameters
  In each case, the values of the relevant object (e.g.WBS element or
  activity) are transferred to the function modules.  There are no return
  parameters.  If the value in a user-defined field (field name USR...) is
  not allowed, an appropriate error message (E...) should be output.
       Enhancement CNEX0001 contains the following components:
     o   EXIT_SAPLCJSS_001: PS Customer-Exit for user-defined fields in the
         standard work breakdown structure
     o   EXIT_SAPLCJWB_001: PS Customer-Exit for user-defined fields in the
         work breakdown structure
     o   EXIT_SAPLCONW_001: PS Customer-Exit for user-defined fields in the
         network
     o   EXIT_SAPLCPDO_001: PS Customer-Exit for user-defined fields in the
         standard network
   Procedure
     For details of how to incorporate enhancements, refer to the system
     documentation or to the online documentation for transaction CMOD
     (project management of SAP enhancements, function exits)
Hope this helps..
