Check Screen Fields in ME21n

Hi,
I have to put a check on Document type and plant combination in ME21n.
After i enter values in Doc Type and Plant and i hit enter it should perform a check.
Check Logic:
I have made a Z table and if the Doc type n plant combination does not exist in that Z table then it should throw an error.
Now my query is,
which exit or badi should i use? i cant find anything related to it.
Thanx in advance
Regards,
Shraddha

Hi shyam...
thanks for your reply...
me_process_po is only for internal use of SAP
me_process_po_cust-
actually i want plant info from item and doc type from header....which is not possible through this badi as the method in which both these parameters are there is not called at the time of enter or save.
rest no other badi is useful.
Do u know about any exit?

shraddha

Grayout of component screen fields in ME21N transaction

Hi experts,
I have a problem while creating subcontracting PO i want to gray out the fields of component screen...in ME21N transaction...is it possible through the screen varient or else should i go for exit ??...could u please help me in finding the right procedure...........
Best Regards,

Go to the screen where u want to make the changes.
Click on System -> Status. Double click on the screen Number (like 1121).
Then on the PBO module screen click on 'Layout'. You will go to graphical screen painter.
Then DOUBLE CLICK on the column/field you want to gray out and on Attribute part, Program Input -> Not possible .(save + activate)
You will need an Access Key to change the standard SAP Screen...

Screen exit for ME21N

Hi friends,
I need steps to create screen field in ME21N using the BADI ME_PROCESS_PO_CUST. Can anybody suggest me how to implement this.
Thanks in advance
Regards
Srikanth S

Hello Srikanth,
To created a screen exit you can use either a BADI or a USER EXIT.
BADI : ME_GUI_PO_CUST
USER EXIT: MM06E005
GO to transaction SMOD
and type MM06E005 and press display.
once inside the user exit, click on components, there you have function Module exits, screen exits and includes.
On the screen exits, you have to decide where you want to add the screen field, whether its on header or item level.
THE go to SE80, type the screen name as the program name. IT will give you all the objects for the particular program.
Choose screens, and then the relevent screen. Go to layout and add the field you want. Save and activate.
You also need to add the field in the Cl_include so that you could pass data and retrive data.
Write the relevant code in Function Modulte Exits.
ITEM LEVEL:
EXIT_SAPMM06e_016
EXIT_SAPMM06e_017
EXIT_SAPMM06e_018
Now you have to add the relevant code in the PAI and PBO module.
Reward if useful.

Modify fields in ME21n

Hello All,
I have a requirement where in I need to modify fields of me21n based on a condition:
if the user enters a value in the field: MEPO1211-KONNR (Contract no./Number of principal purchase agreement) , then all the conditions (From KOMV table) fileds & all the Pricing terms should be disabled for change/input i.e. should be in display mode.
I tried to search for an exit for this but could not find an appropriate one to modify screen fields however, the alternae to this requirement is :
If the user enters a value in the field: MEPO1211-KONNR (Contract no./Number of principal purchase agreement) , then on entry of the conditions(TABLE KOMV) fields and pricing terms user should get an error message so that he cannot proceed.
Please suggest me a solution for any of the above two requirements.
Any help on this would be highly appreciated.

Screen Badi in ME21N

Hi Experts.....
I have implemented a screen exit in ME21N Transaction to add custom fields. With this I could get an extra custom tab in which I have included my fields. Now my req is to get multiple tabs as the fields are more in number. So I wanted to implement this using a BADI. I have searched the BADI named ME_GUI_PO_CUST.
in this I have passed the screen no and program name and label name along with element as PO and name of view as HEADER. But I cannot see an extra TAb in header details. I also created the subscreen and the corresponding program...
Can anyone help me to implement a screen badi in ME21N.
Thank you in advance

Hi Shakti,
The BADI ME_GUI_PO_CUST has an example implementation class CL_EXM_IM_ME_GUI_PO_CUST. Check the method SUBSCRIBE to see how the BADI can be subscribed.
The reason why your custom screen is not appearing is probably because your BADI implementation is not active or the custom screen has not be subscribed properly.
The code inside method SUBSCRIBE of your BADI implementation should be 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 = 'ITEMSCREEN1'.
* 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 = 'MEPO_BADI_STRUCT'.
* a label can be defined
ls_subscriber-label = 'BAdI customer'.
* 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.
To impelement multiple tabs you have to subscribe each tab differently using the parameter
ls_subscriber-name
of the BADI
and also name each tab differently using
ls_subscriber-label
Let us assume that you have to implement three tabs, then you have to subscribe each tab with a different name and also label each tab differently.
You can name subscribe the first tab with name ITEMSCREEN1 label BAdI customer, subscribe 2nd tab with name ITEMSCREEN2 label BAdI customer'2 and subscribe 3rd tab with name ITEMSCREEN3 label BAdI customer3.
Mention a different positions for each tab.
Like say for BADI customer1 ls_subscriber-position = 5., for BADI customer2 ls_subscriber-position = 6. and for BADI customer3 ls_subscriber-position = 7..
Also append the subscribe data three times for the three tabs.
This will display three tabs with names BADI customer1, BADI customer2 and BADI customer3.
Hope the above information helps.

Abhisek.

Material Field in ME21N

Dear,
When i go to ME21N and try to create a NB PO type after when i entered the vendor in the item overview tab material field didn't appear at all. when i just opened the ME21n at that time material field was appearing whats the problem.
Regards,
qsm sap

Hi,
For the Document type NB check the screen layout and check the config in SPRO for screen layout wther this field is supress or Not. Also for ME21N layout do check this field in customozation in Define Screen Layout for PO document type. If it is not supressed check wther you are giving or by default if the Acc Assignment category is appearing other then standard.
Also check if for other document type the Material field for this vendor is coming or not.
Thanks

How to create a F4 help for a report selection screen field

hi,
can any one guide me to create F4 help for a field in a selection screen in a report program,plz give me a sample code

hi,
Here are the following ways
1.with the help of match code objects we can create the F4 Functionality for Field.
Syntax is :
PARAMETERS: p_org LIKE t527x-orgeh MATCHCODE OBJECT zorg.
2. One more thing is we can do it with Search Help's also.
3. Even we can do it HELP Views also.
Help Views:
You have to create a help view if a view with outer join is needed as selection method of a search help
The selection method of a search help is either a table or a view. If you have to select data from several tables for the search help, you should generally use a database view as selection method. However, a database view always implements an inner join. If you need a view with outer join for the data selection, you have to use a help view as selection method.
All the tables included in a help view must be linked with foreign keys. Only foreign keys that have certain attributes can be used here. The first table to be inserted in the help view is called the primary table of the help view. The tables added to this primary table with foreign keys are called secondary tables.
The functionality of a help view has changed significantly between Release 3.0 and Release 4.0. In Release 3.0, a help view was automatically displayed for the input help (F4 help) for all the fields that were checked against the primary table of the help view. This is no longer the case in Release 4.0.
As of Release 4.0, you must explicitly create a search help that must be linked with the fields for which it is offered (see Linking Search Helps with Screen Fields ).
Existing help views are automatically migrated to search helps when you upgrade to a release higher than 4.0.
A help view implements an outer join, i.e. all the contents of the primary table of the help view are always displayed. You therefore should not formulate a selection condition for fields in one of the secondary tables of the help view. If records of these secondary tables cannot be read as a result of this selection condition, the contents of the corresponding fields of the secondary table are displayed with initial value.

Regarding Selection-Screen Field Display

Hi All,
I have issues with Selection-Screen field display.
The Actual issue is i had declared a selection screen field as: s_exgen FOR embk-exgen.
EMBK-EXGEN is actually 20 Char length field.
But in output display it is being shown as 18 Char field though i can type in all 20 characters.
But display restricted to 18 Characters only.
Can anybody give me the solution for the same!
Thanks in advance.
Thanks & Regards,
Prasad.

Hi,
You can decrease the visible length of the field but you can not increase more than database field length. check SAP help on this :
select-options: s_exgen FOR embk-exgen VISIBLE LENGTH 5.
... VISIBLE LENGTH vlen
Effect
This addition allows you to shorten the visible length of the corresponding screen field on the selection screen to vlen.
Variant 2
SELECT-OPTIONS sel FOR (f).
Additions as in variant 1.
Effect
In this variant, (f) must be a field containing the name of the actual reference field at runtime. The system creates the LOW and HIGH fields as character fields with length 45. However, their appearance on the selection screen is inherited from the reference field whose name is contained in field f at runtime.

Appana
