Custom fields not showing on table output - abap

Question

I'm having trouble figuring out why two custom fields are not showing up in transaction VA05 (its output to be specific).
Before reading below: I didn't make any changes to the program because I wasn't assigned to this task. One of my colleagues did this change.
I followed this tutorial, which explains how to expand the VA05 output table with custom fields.
I didn't actually followed this guide. I followed this tutorial only to understand what my colleague might have done to achieve what we need and what might be needed to fix the issue.
So, as the tutorial suggests, this is what should be done in short:
Go to SE11 and search for VBEP Database table and click display.
Click on Append Structure
Click on Create Append
Insert the name of the append name, in my case it's ZZVBEP_MECC
Insert two fields: ZZDELIVERYDATE and ZZREQDELIVERYDATE
Save and activate
If you go to VBEP table now, you'll see at the bottom the field .APPEND with the column Data Element set to ZZVBEP_MECC.
Now, following the tutorial, the include program V05TZZMO need to be changed, and here's ours:
***INCLUDE V05TZZMO .
* This form is called in the include LV05TFMO.
FORM MOVE_USERFIELDS USING ZP.
CASE ZP.
WHEN 'VBAK'.
WHEN 'VBAP'.
CHECK LVBAP-PSTYV NE 'ZRAC'.
CHECK LVBAP-PSTYV NE 'ZCAC'. "Escl.acconti
MOVE LVBAP-KDMAT TO LVBMTV-ZZKDMAT.
PERFORM OFFENE_AUFTRAGSMENGE.
SELECT SINGLE * FROM VBKD WHERE VBELN = LVBAP-VBELN.
IF SUBRC = 0.
MOVE VBKD-KDGRP TO LVBMTV-ZZKDGRP.
ENDIF.
WHEN 'VBEP'.
MOVE LVBEP-ZZDELIVERYDATE TO LVBMTV-ZZDELIVERYDATE.
MOVE LVBEP-ZZREQDELIVERYDATE TO LVBMTV-ZZREQDELIVERYDATE.
ENDCASE.
ENDFORM.
When I run VA05 however, these two custom fields are not there nor are in the Change Layout screen.
Is it possible that the code in V05TZZMO is not in the right place? Looking at the tutorial's code I saw that they put those statements in WHEN 'VBAK' instead of WHEN 'VBEP'.
Also, the ENHANCEMENT 1 ZZ_SD_VBAK_VA05 is not present in my code.
There might be something I missed. As I said above, I didn't make these changes so I cannot tell exactly what my colleague did.

Answer 1

Custom fileds also must be included in the structure VBMTVZ.

Answer 2

Finally solved.
Here's the procedure step-by-step we followed in order to fix the issue:
Create an Append Structure
Go to TCode SE11 and open database table VBMTVZ
Click on Append Structure...(It's in the program's toolbar) - or Goto > Append Structure
Create a new Append Structure(There's a button for it)
Enter the name of the structure(in our case was ZZVBMTVZ_MECC
A new structure is then created. Enter the needed components/fields
Save and activate the structure.
Note: To check if the structure is actually appended, go back and open table VBMTVZ again. At the end of the list of fields there must be one field called .APPEND with the type set to the name of the structure you created. After this field, there's also all your fields you created on that structure. See the image below for reference.
Change V05T program
Now you'll need to make some changes to the program linked to the TCode VA05.
To do this:
Go to TCode SE80.
Select Function Group and insert V05T as the name of the group.
Open the sub-folder called Includes and look for V05TZZMO
Open this include file in change mode.
The file should look like this:
***INCLUDE V05TZZMO .
* This form is called in the include LV05TFMO.
FORM MOVE_USERFIELDS USING ZP.
CASE ZP.
WHEN 'VBAK'.
* header
* MOVE LVBAK-XXXXX TO LVBMTV-ZZXXXXX.
WHEN 'VBAP'.
* item
* MOVE LVBAP-XXXXX TO LVBMTV-ZZXXXXX.
WHEN 'VBEP'.
* schedule line
* MOVE LVBEP-XXXXX TO LVBMTV-ZZXXXXX.
ENDCASE.
ENDFORM.
Add the following line of code to the WHEN 'VBEP'. code block.
MOVE LVBEP-name_of_your_field TO LVBMTV-name_of_your_field
You need to add that line for each field you appended.
In my case, the final result was the following:
***INCLUDE V05TZZMO .
* This form is called in the include LV05TFMO.
FORM MOVE_USERFIELDS USING ZP.
CASE ZP.
WHEN 'VBAK'.
* header
* MOVE LVBAK-XXXXX TO LVBMTV-ZZXXXXX.
WHEN 'VBAP'.
* item
* MOVE LVBAP-XXXXX TO LVBMTV-ZZXXXXX.
WHEN 'VBEP'.
* schedule line
* MOVE LVBEP-XXXXX TO LVBMTV-ZZXXXXX.
move LVBEP-zzdeliverydate to lvbmtv-zzdeliverydate.
move LVBEP-zzreqdeliverydate to lvbmtv-zzreqdeliverydate.
ENDCASE.
ENDFORM.
Save the file and activate the program.
At this point you should be able to see your fields in the output of TCode VA05.
Notes
In order to be able to change the include program V05TZZMO you need an Access Key. Without that you cannot change the program.
If the fields you appended aren't showing even after activating, try:
To logout and log back in or
reset the buffer with this TCode /$SYNC
