Add new screen in ME23N with BADI ME_GUI_PO_CUST

Hi folks, I have used the BADI ME_GUI_PO_CUST to add a custom tab in transaction ME23N.
So good, sor far, I know how to used BADI and it works very well. I had to subscribe my own subscreen in the method subscribe of the interface, but something is boring me and I don't know if it's possible.
Let's say I want to display my new tab according to the purchasing document type. Right now, my custom tab is always display. There is no method to unsubscribe a screen in the interface. What I could do is to used the get parameter id 'BES' in the subscribe method to get the current purchasing document display, then from there I could decide if I subscribe or not my own screen. The thing with the subscribe method is that it's only called once, when you enter in the transaction, if you stay in the transaction and select another purchasing document, this method will not be called.
thanks
Alex

Hi Alexandre,
First get the current Purchase Order Number using parameter ID 'BES' in the PBO of the custom subscreen.
Then based on validation checks set SCREEN-INVISIBLE = 1 and SCREEN-ACTIVE = 0 and MODIFY SCREEN for all the screen fields.
This will hide all the fields and eventually the tab may also disappear. This works for Screen Exits (i.e., if all the fields of a tab are made to disppear then the tab also disapears if is the tab is defined using Screen Exit). But I have never tried it out in a BADI.
Try this, it might work.
Hope it helps.
Regards,
Abhisek.

New screen in ME23N with BADI ME_GUI_PO_CUST

Hello to all developers,
I was able to add a new (sub-)screen in the header data ME23N.
All fields are shown.
When I switch the mode to "CHANGE", all fields disappear and of course no tab is shown.
If someone has an idea, please let me know.
Many thanks in advance.
H.-J. Schmidt

Hi,
Please check if in the PBO module of the custom subscreen you have set SCREEN-INVISIBLE = 1 or SCREEN-ACTIVE = 0.
Also check if the screen has been properly subscribed in method SUBSCRIBE (i.e., remove all transaction type checks from this method).
Since the screen and tab is being displayed in ME23N, it should also be displayed in ME21N (or create mode) and in ME22N (or change mode). The only condition under which the tab and screen might not appear is, if any checks based on the T-code or Transaction type is done and SCREEN-INVISIBLE = 1 or SCREEN-ACTIVE = 0 have been set.
And if you are using OOPS concept in handling the PBO and PAI, then check if the proper values are set using different methods of the class.
Hope this helps.

Abhisek.

No, I won't explain it in detail - you need to read the documentation and at least make an attempt at the process on your own first. The documentation is right there in the IMG where I said it was but here's the path since you can't find it:

Is it possible to add new screen fields to the transaction /dsd/sl_cockpit

HI experts,
Would like to know if it is possible to add new screen fields to the cloned version of /dsd/sl_cockpit.
I cloned the original transaction /dsd/sl_cockpit into a diff. name, now I want to know how I can include/ add those new fields to this transaction. It looks like the screen is dynamically built using Standard ABAP classes. Need help.
Thanks in advance

it is not possible to add new fields via badi on /dsd/sl_cockpit.

SOLUTION: tab not showing in ME21N/ME22N with badi ME_GUI_PO_CUST

Hi,
I implemented BADI's ME_GUI_PO_CUST and ME_PROCESS_PO_CUST to show a custom tab in the header section of ME21N, ME22N and ME23N.
But after implementing the BADI's, the tab showed up in ME23N, but not in ME21N and ME22N.
So I started looking for a solution in the SDN forum, and I saw that there were a LOT of people with the same problem, but nobody ever posted a solution.
So here is the solution:
So, I added the fields I wanted to show in the structure CI_EKKODB, implemented the BADI ME_GUI_PO_CUST (the methods SUBSCRIBE and MAP_DYNPRO_FIELDS), and the BADI ME_PROCESS_PO_CUST.
After that the tab showed up in ME23N, not in ME21N or ME22N.
So I found an SAP note saying the following:
Question:
I implemented the 'ME_GUI_PO_CUST' Business Add-In to display customer-
specific tab titles in the EnjoySAP purchase order. They are only shown in display mode (ME23N) however, not in create or change. Why?
Solution:
You may have forgotten to assign a field status to the user-defined fields on these tabs. As a result, the system automatically interprets the field status as 'hidden' in create and change modes. However if a tab contains only hidden fields, then the entire tab is set to hidden. In display mode, fields without a field status are automatically set to display. That is why the tab is displayed in this case.
To assign a field status to the user-defined fields, use the methods provided for this purpose in the Business Add-In 'ME_PROCESS_PO_CUST' (compare sample source code in the FIELDSELECTION_ITEM method).
So in my case, I had to add some code to the FIELDSELECTION_HEADER method of the BADI ME_PROCESS_PO_CUST.
This is the code:
method IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_HEADER.
DATA: l_persistent TYPE mmpur_bool.
FIELD-SYMBOLS: <fs> LIKE LINE OF ch_fieldselection.
* if the item is already on the database, we disallow to change field badi_bsgru
l_persistent = im_header->is_persistent( ).
*   IF l_persistent EQ mmpur_yes.
    READ TABLE ch_fieldselection ASSIGNING <fs> WITH TABLE KEY metafield = mmmfd_cust_01.
    IF sy-subrc IS INITIAL.
      <fs>-fieldstatus = '*'. " Input
    ENDIF.
*   ENDIF.
endmethod.
But then, I realized that this BADI was never triggered. When I entered one of the transaction codes ME21N, ME22N or ME23N, the code in the fieldselection_header method was never executed.
So I went to transaction SE18, and entered ME_PROCESS_PO_CUST in 'Enhancement Spot' and pushed the button display.
And there in the tab 'Enhancement Implementations', I saw an implementation that was not mine, and that did not show up in the overview of the SE18 'BADI NAME' tab for the same BADI... which to me seems strange.
So as you may know, there can never be more than one active implementation of the BADI ME_PROCESS_PO_CUST.
So I disactivated my implementation and put my code in the existing implementation.
And after that it worked!

implement first badi :ZME_GUI_PO_CUST:
METHOD if_ex_me_gui_po_cust~subscribe.
DATA: ls_subscriber LIKE LINE OF re_subscribers.
* we want to add a customer subscreen on the item detail tab
   CHECK im_application = 'PO'.

* the height of the screen can be defined here. Currently we suport two screen sizes:
* value <= 7 a sevel line subscreen

   ls_subscriber-height = 7.
   APPEND ls_subscriber TO re_subscribers.
ENDMETHOD.

Custom screen not displaying using BADI ME_GUI_PO_CUST

Hello Experts,
I was working on BAD ME_GUI_PO_CUST to add custom subscreen on header
I have created a subscreen ZNRD_SAPMEGUI_PO with number 9999.
I have created implementation of ME_GUI_PO_CUST as ZME_GUI_PO_CUST.
I have added screen details to the BADI.as follows
CALLPROGRAM = SAPLMEGUI.
Scr No = 1102
Subscreen area = TABSTRIPCONTROL2SUB
Program called = ZNRD_SAPMEGUI_PO
Scr no = 9999.
Now to the method SUBSCRIBE to the implemented BADI ZME_GUI_PO_CUST
I have wriiten the following codes.
method if_ex_me_gui_po_cust~subscribe.
data: ls_subscriber like line of re_subscribers.
if sy-tcode eq ' ME21N' or sy-tcode eq 'ME22N' or sy-tcode eq 'ME23N'.
check im_application = 'PO'.

endif.
endmethod.
BADI is active
Now when irun ME21N i dont see the additional custom tab on header coming up.
Please guide will be appreciated.

i have implemented method SUBSCRIBE in ME_GUI_PO_CUST to create new tab in ME21N,
but the tab is not coming
following is the code snips, please tell where is the error, or some setting needs to be done
method IF_EX_ME_GUI_PO_CUST~SUBSCRIBE.
DATA: ls_subscriber LIKE LINE OF re_subscribers.
if sy-tcode eq ' ME21N' OR SY-TCODE EQ 'ME22N' OR SY-TCODE EQ 'ME23N'.
CHECK im_application = 'PO'.
CHECK im_element     = 'HEADER'.
CLEAR re_subscribers[].
ls_subscriber-name = 'Customer-Data'.
ls_subscriber-dynpro = '0101'.
ls_subscriber-program = 'SAPLMEGUI'.
ls_subscriber-struct_name = 'MEPO_SUBSCRIBERS'.
ls_subscriber-label = 'Customer Data'.
ls_subscriber-position = 10.
ls_subscriber-height = 7.
APPEND ls_subscriber TO re_subscribers.
ENDIF.
endmethod.

Hi...I hv similar requirement.
I need to show a custom field in the screen for the items.
I tried using the methods "SUBSCRIBE" and "MAP_DYNPRO_FIELDS" as explained in the sample code.
Below is my code. I have copied the sample code and changed it lil.
Method "SUBSCRIBE":
DATA: ls_subscriber LIKE LINE OF re_subscribers.
we want to add a customer subscreen on the item detail tab
CHECK im_application = 'PO'.
CHECK im_element     = 'ITEM'.
each line in re_subscribers generates a subscreen. We add one subscreen in this example
CLEAR re_subscribers[].
the name is a unique identifier for the subscreen and defined in this class definition
ls_subscriber-name = subscreen1.
the dynpro number to use
ls_subscriber-dynpro = '9000'.
the program where the dynpro can be found
ls_subscriber-program = 'SAPLZMMPO1'.
each subscreen needs his own DDIC-Structure
ls_subscriber-struct_name = 'ZMM_PO_CUST_SCREEN'.
a label can be defined
ls_subscriber-label = text-t01.
the position within the tabstrib can be defined
ls_subscriber-position = 13.
the height of the screen can be defined here. Currently we suport two screen sizes:
value <= 7 a sevel line subscreen
value > 7 a 16 line subscreen
ls_subscriber-height = 7.
APPEND ls_subscriber TO re_subscribers.
method "MAP_DYNPRO_FIELDS":
FIELD-SYMBOLS: <mapping> LIKE LINE OF ch_mapping.
*- customer fields
CONSTANTS: mmmfd_cust_01 TYPE mmpur_metafield VALUE 90000000.
LOOP AT ch_mapping ASSIGNING <mapping>.
    CASE <mapping>-fieldname.
      WHEN 'CLMNO'. <mapping>-metafield = mmmfd_cust_01.
    ENDCASE.
ENDLOOP.
I created a function group - "ZMMPO1" and created the subscreen 9000 in that. I placed the custom field in that screen. Tha main program of ZMMPO1 is "SAPLZMMPO1".
I created a structure also - "ZMM_PO_CUST_SCREEN".
I want to know whether this is sufficient to display the tab on the screen or am I missing something.
It is mentioned that the implementation of "ME_PROCESS_PO_CUST" is a pre-requisite.
could you lemme know the process please.
Thanks,
Ram.

Unable to add custom tab in ME21N using BADI ME_GUI_PO_CUST

Dear All,
I need one extra tab in Item Details of ME21N.
This extra tab should have two fields of my own.
I have put the coding in the SUBSCRIBE method of the implementation of the BADI ME_GUI_PO_POST as follows:
data: ls_subscriber like line of re_subscribers.
we want to add a customer subscreen on the item detail tab
check im_application = 'PO'.
check im_element = 'ITEM'.
each line in re_subscribers generates a subscreen. We add one subscreen in this example
clear re_subscribers[].
the name is a unique identifier for the subscreen and defined in this class definition
ls_subscriber-name = 'Event Details'.
the dynpro number to use
ls_subscriber-dynpro = '0001'.
the program where the dynpro can be found
ls_subscriber-program = 'SAPLMEPOBADIEX'.
each subscreen needs his own DDIC-Structure
ls_subscriber-struct_name = 'ZSM_PO_STRUC'.
a label can be defined
ls_subscriber-label = 'Event ID'.
the position within the tabstrib can be defined
ls_subscriber-position = 5.
the height of the screen can be defined here. Currently we suport two screen sizes:
value <= 7 a sevel line subscreen
value > 7 a 16 line subscreen
ls_subscriber-height = 7.
append ls_subscriber to re_subscribers.
I put breakpoints in the implementation of the method, and it is going into it, yet the extra tab is not getting displayed on the screen.
Please give your suggestions on this.
Regards,
Prosenjit.

Hi Prosengit,
I am not aure about u r BADI,
BUt last week i have custom tab in the PO header data using this enahncement 'MM06E005'.
IN thi senhancement u have thrre screen exits.In this enhancement
SAPMM06E 0111 CUSTSCR1 SAPLXM06 0111 Subscreen: PO item
u can add subscreen and u can add u r own fields here .
and u can write u r code in 'EXIT_SAPMM06E_006'.
if u want to change the title of the program.
Go to program SAPLXM06 then go to text element give text symbol no as '111' and u can change the title of u r tab.
I hope this solves u r problem.

How to Add New Parameter in Cluster with LabVIEW Executable Program?

   In this VI，it can write the parameter in Cluster to the database (Access 2003).it run well.
   But When I add another parameter in Cluster,such as EE,I have to modify this Cluster. And at the same time,I have to modiy the database (I should add a column of EE).if this vi build to exe, how can I achieve it?Can LabVIEW have any way to increase new parameter EE in Cluster and in Database in executable program?
   Would you give me some advice?Thank you

It's rather unclear what you try to do here. In your first post you talk IMHO about the high level Datatbase Toolkit functions that take a cluster and translate it automagically into the appropriate SQL Query/Update.
Your second question seems to be about the user interface of your application.
Proper application design would mean to separate the user interface aspect from the actual database query in some ways. I definitely wouldn't use the same cluster for both. Also if you simply hide a control on the frontpanel (possible also in an executable) it still is present logically and if you end up using the high level database toolkit functions with that cluster it will result into a query or update of the database with all the data in the cluster, also the hidden ones.
