Extend VL06 transaction adding new field in output layout – SAP ECC

A good article and OSS note if you need to extend the standard ABAP SAP ECC transaction VL06 to display outbound deliveries details.

VL06: Insert fields to LIPOV



OSS Note 128150: https://me.sap.com/notes/128150


Extend LIPOVZ structure with your append structure and fields.

LIPOVZ is included in LIPOV structure which is used in report VL06.

If the name of the new fields are the same as in LIKP / LIPS, then the values will be auto populated.

But if you want to get values from other fields (like SO VBAK, or VBKD table), then you have to implement user-exit (extension name) via transaction SMOD assigning: V50Q0001

And in function module EXIT_SAPLV50Q_001 you have to create include ZXV50QU01 in which to put your code. Loop at CT_POSTAB and determine the value and change the field in the item of this internal table. Note: this exit is called for all items at once!

Sometimes you need to reset the buffers:
Note : BALVBUFDEL program must be run with SE38 for deletion of last buffer . Details on oss note 122975.

Gmail.com – more info on how ids work and two tricks

1st: You can append a plus “+” sign after your name

So adding any text after “+” sign still get the emails to your inbox, but you can filter based on this additional email id. E.g.:

your.email@gmail.com and your.email+subscription1@gmail.com and your.email+bank1@gmail.com

will both deliver the emails to your.email@gmail.com !

2nd: Gmail DOES NOT recognize the dots “.” in the email ID.

So your.email@gmail.com is the same as youremail@gmail.com or y.o.u.r.e.m.a.i.l@gmail.com

Fix VirtualBox (copy/move/restore) VM

If you have moved a VM or have an old copy of working VM, you can land in situation where the VirtualBox software is reinstalled or moved and you get errors when you restore old VMs or move some.

Could not find an open hard disk with UUID {2219b9d1-8931-418c-a7d5-d5ce00c81b7c}.
Result Code:


Virtual Box UUID {17c3.........} does not match the value {3c1b...} 
stored in the media registry ('/home/user/.VirtualBox/VirtualBox.xml')
Machine UUID {899a89219ax-7d55-8381-01ac-288288101} doesn't match its UUID {0388cb75-f076-4992-ab96-ed8d2ff99623} in the registry file
Result code: NS_ERROR_FAILURE (0x80004005}

The solution I found is based on the answers here:

https://stackoverflow.com/questions/15074878/virtual-box-uuid-07c3-does-not-match-the-value-2c1b-stored-in-th and my experience.

First – check if you have running the VirtualBox with the right user! Sometimes errors can occur if you have installed the VirtualBox with different user and the current one is not admin or does not have enough rights!!!

Second – fix the UUID like below.

Copy existing VM (duplicate) via VirtualBox to create a new folder and working VM.

Rename the VirtualBox.vdi file to VirtualBox0.vdi of the new VM.

Get the UUID of the working VM with the following command:

The result should look like:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands dumphdinfo VirtualBox0.vdi
--- Dumping VD Disk, Images=1
Dumping VD image "polikont_feb2016-disk1.vdi" (Backend=VDI)
Dumping VDI image "polikont_feb2016-disk1.vdi" mode=r/o uOpenFlags=9 File=0x0002586d731290
Header: Version=00010001 Type=1 Flags=0 Size=85888373760
Header: cbBlock=1048576 cbBlockExtra=0 cBlocks=81910 cBlocksAllocated=13687
Header: offBlocks=512 offData=328192
Header: Geometry: C/H/S=1024/255/63 cbSector=512
Header: uuidCreation={0388cb75-f076-4992-ab96-ed8d2ff99623}
Header: uuidModification={24bde4bc-e7cf-4d60-8f40-a257b3460228}

Set UUID to the restored/copied VM which was giving error (I have renamed it to VirtualBox.vdi in the directory of the working copy, after I have renamed the working VDI to VirtualBox0.vdi and taken its UUID as shown above). So set its UUID as follow:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands sethduuid  VirtualBox.vdi 0388cb75-f076-4992-ab96-ed8d2ff99623

Replace the UUID (0388cb75-f076-4992-ab96-ed8d2ff99623) with your result from dumphdinfo command!

*** This was experienced and tested in VirtualBox 7.0 under Windows 10 at May 2024.

S/4HANA material segmentation, Country of Origin (CoO) in MIGO

SAP ERP doesn’t directly capture the country of origin during a MIGO goods receipt for a newly created batch. However, you can achieve this through implementing a User Exit.

Additional batch data, such as the country of origin, region of origin, and freely available date fields, can be changed only in user exits. To create a new batch for the goods movement, use the exit EXIT_SAPMM07M_003.

MCHA-HERKL is not automatically updated based on the purchase order during a goods receipt. You must use user exit EXIT_SAPMM07M_003

The user-exit EXIT_SAPMM07M_003 is in
Enhancement: “MBCFC003” – Maintenance of batch master data for goods movements”
(Use transaction: CMOD to activate the exit and assign enhancement).

Question: Why is the user exit EXIT_SAPMM07M_003 processed for some batches but not for others?

Answer: The user exit EXIT_SAPMM07M_003 is processed only if the batch is newly created by the goods movement. This may have different consequences depending on the batch definition level.

To determine the country of origin (CoO) you can use proper setup of segmentation field. Documentation here:

Principle 80:20 in human body -water, microbiome and more… Принципът 80:20 и в човешкото тяло

60% water in adult human body…

Up to 60% of the human adult body is water. According to Mitchell and others (1945), the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

a от останалите 40% – 50% са чужди… (and in the left 40% more than 50% are not “human” cells):

In an article by the Scientific American (which has published articles by over 200 Nobel Prize winners) revealed that only 47% of our cells are human.

What about the other 53%?

Well, they’re made up of the bacteria, fungi and viruses living within us collectively known as your microbiome.

And it’s the newest discoveries about the microbiome, specifically in your gut, that scientists are calling “the most exciting prospect in medicine since the discovery of DNA.”


Мани стана като БГ изборите – 20% определят останалите 80% (So it sound like the result of the recent Bulgarian elections – 20% determines the result).

Богатството наподобява морската вода, от която жаждата ти се увеличава, колкото повече пиеш.

Здравето не е всичко, но без здраве всичко е нищо.

Който критикува придирчиво другите, работи над своето самоусъвършенствуване.

Който не обича самотата – той не обича и свободата.

От гледна точка на младостта живота е безкрайно бъдеще; от гледна точка на старостта – много кратко минало.

Повечето хора са толкова субективни, че всъщност не се интересуват от нищо освен от самите себе си.

Моята философия не ми донесе нищо, но ми спести много.

Чрез цитати изтъкваш ерудицията си и жертваш оригиналността си.

Човек, който пише за глупаци, винаги може да разчита на широк кръг от читатели.

Да страдаш, че някога вече няма да те има, е също тъй нелепо, както да страдаш за това, че някога още не те е имало.

Сполетялото ни нещастие не ни измъчва толкова, колкото мисълта за обстоятелствата, при които би могло да бъде избегнато.

Хората са общителни само поради своята неспособност да понасят самотата, тоест себе си.

Инвестиции в акции – опит, идеи, полезни страници

Добра идея и предложение:

Как искам да се променят законите за ДДС за да се премахне парадокса “ДДС за инвеститори” или когато



Защото “облагаем” оборот за регистрация не значи оборот, който се облага с ДДС. “Облагаемият” оборот за регистрация не се облага с ДДС, но го наричат облагаем, защото така са си го дефинирали в закона.

Това е подигравка.

Това е все едно да наричат котките кучета и да карат хората да попълват декларация за притежание на куче, въпреки че притежават котка.

Google Drive API v3 (googleapiclient.errors.HttpError 404 File not found)

If you try to upload a file in a shared drive (in Google Drive) you may get the above error.

This is my experience and solution as of February 2024 using Python 3.10.

from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload
from google.oauth2 import service_account

from io import BytesIO
from googleapiclient.http import MediaIoBaseUpload
from google.cloud import translate_v2 as translate

## Credentials of service account
credentials = service_account.Credentials.from_service_account_info(service_account_info, scopes=['https://www.googleapis.com/auth/drive'])

## API Client Service
service = build("drive", "v3", credentials=credentials)

# buffer_memory=BytesIO(b"some initial binary data: \x00\x01") # BytesIO() new_body
buffer_memory=BytesIO() # BytesIO() new_body

## Prepare the file in memory (you can upload local file too with MediaBase Upload)
media_body = MediaIoBaseUpload(buffer_memory, mimetype='text/html', 
        chunksize=1024*1024, resumable=False)
                body = {
                        'title': file_name,
                        "name": file_name,
                        "mimeType": "application/vnd.google-apps.document",
                        "driveId": "0APee............PVA",
                        "parents": ['0APe.............PVA'],

## Upload file
returned_fields="id, name, mimeType, size, webViewLink, exportLinks"
upload_response=service.files().create( body=body,                                                            

## Share the created file with user
user_permission = {
                    "type": "user",
                    "role": "writer",
                    "emailAddress": share_user,
                perm_response = service.permissions().create(

The important difference between uploading in private Google drive is that you have to use the following parameters for Shared Drives:

driveId -> Id of Shared Drive
parents -> Folder or Shared Drive

Mime Types: List of the supported Mime type here


If you want to convert the uploaded file to Google Drive native format use the following parameter:

"mimeType": "application/vnd.google-apps.document",

Google documentation: https://developers.google.com/drive/api/guides/manage-uploads

And this article on StackOverflow as well helped to find the solution although some parameters are wrong or deprecated already: https://stackoverflow.com/questions/67622131/google-drive-api-v3-googleapiclient-errors-httperror-404-file-not-found

How to convert StringIO object to BytesIO object vice versa.

I want to read a string with the io.StringIO and then convert it to an io.BytesIO object and vice versa, how can I do this?

Below is the example source code which can implement python StringIO and BytesIO object converts.

import io
# Convert a StringIO object to BytesIO object.
def stringio_to_bytesio(str):
    str_io_object = io.StringIO(str)
    str_data = str_io_object.read().encode('utf8')
    bytes_io_object = io.BytesIO(str_data)
# Use io.TextIOWrapper to convert BytesIO object to a string. Then we can build a StringIO object on the string.     
def bytesio_to_stringio(bytes_str):
    data = io.BytesIO(bytes_str)
    # Create an instance of io.TextIOWrapper class.
    text_wrapper = io.TextIOWrapper(data, encoding='utf-8')
    str = text_wrapper.read()
    str_io_object = io.StringIO(str)
if __name__ == '__main__':
    bytes_str = stringio_to_bytesio('I love python')
    bytesio_to_stringio(b'hello python')
