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,
shanker

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...

Item level Info record PO text field in Purchase Order Me21n transaction

Hello All,
I have to enter some information in the PO info record text field (which is in Item level Texts tab of ME21n transaction ) using an user-exit at the time of creation/change of purchase Order.
Does anyone knows the user-exit and how to update the text field ?
Any help is really appreciated
Thanks
Ricky

Check with : Enhancement : MM06E005
Function module : EXIT_SAPMM06E_017
This user exit will trigger when you enter the data in item level(Both creation and change)

RSCRM: Query date with customer exit variable

Hi All,
Is there any way to run the RSCRM transaction with a query with a customer exit variable for a date characteristic?
The issue is that the query ran ok but the variable is not being updated when the RSCRM query is running with a background job or a process chain.
Thanks in advance
EV

I do not think you can select Customer Exit variable, if you see the type is selected to Char Value Variables and it is not editable.
It would be suggested to go for Customer Exit procesing type for your text variable.

Capture error messages in message log in ME21n transaction

Hello friends,
i have a question here.I have created a Z-table which contain data about material groups which will not be used for the particular plant.when we create a PO now ,i am checking for each line item whether the material group entered for each line item exists in Z-table or not.If exists then throw a message 'XXXXXXXX.'
as this is an enhancement to Me21n transaction , i am using User exit EXIT_SAPMM06E_012 .Now my problem is for each line item i am checking for condition and throwing a message.My requirement is show up all messages(for eg : If more than 1 line item contain errors for the same condition) in the message log of the transaction ME21n screen.I dont think we can do this in the User exit as showing up messages in ME21n is standard functionality
Could anyone please give any idea how to achieve this??
Thanks in advance!

Hi,
You may write to application error log or call screen to show error log in user exit.
Cheers.

Me21n User-Exit / BADI

Hi all,
Anybody knows an User-Exit / BADI to use when you click over SAVE icon on me21n transaction?
I have a 4.6 version...
Thanks!

Dear Julian,
First you would need to find all the available enhancements. The ABAPer would check what are all the enhancements getting triggered when save button is pressed in ME21N by putting break-points.
Please check this sample program from other thread to find BADI and enhancement for a given transaction code. You just need to create a custom program in your system by cut and paste below codes.

Alternatively, you can do the following:
1. For what ever transaction u want the enhancement .. just check for the System-->status (menu) and find out the PROGRAM name....
2. Double click on to the program name and go inside the program (Abap editor)
3. Search for "Call Customer-function " ... and u'll get some search results .. If u get results then u have enhancement in that tcode .....
4. Then it actually calls a Function module .... copy the Function module name .... go to SE80 (object navigator) click on "Repository Information system" then Customer Enhancements .... Give the Function module name in the "Components" field and click Execute ....
ull get a list of Enhancements related to that Componene....
5. Choose which ever enhancement will suit ur business need ..
6. Go to CMOD... create a project .... assign ur enhancement ... and then code ur logic.... activate ur enhancement in CMOD ....... Ur Buisness need will be solved...
For a user exit......
Finding whether there is any User Exit or not for tcode VA42
1. For what ever transaction u want the user exit .. just check for the System-->status (menu) and find out the PROGRAM name.... ( The program name would be for our scenario "SAPMV45A" )
2. Double click on to the program name and go inside the program (Abap editor)
3. Search for the word "USEREXIT" .... u ll find all the user exits in the search result .. and find ur's then ...

SAP Query in SQVI transaction

Hi All,
I have created a Query in SQVI transaction, How to assign a transaction code for it.
Thanks in advance
Raju

hi,
follow the link:
http://help.sap.com/saphelp_erp2005/helpdata/en/b7/26ddebb1f311d295f40000e82de14a/frameset.htm
you will get full information about SAP Query.
There is no SQV1 transaction.
SQ01 --> maintain query
SQ02 --> maintain info set
SQ03 --> maintain user groups
he SAP Query application is used to create reports not already contained in the default. It has been designed for users with little or no knowledge of the SAP programming language ABAP.
SAP Query offers users a broad range of ways to define reports and create different types of reports such as basic lists, statistics, and ranked lists.
Features
The SAP Query comprises five components: Queries, InfoSet Query, InfoSets, User Groups and Translation/Query.
hope this may help you,

ME21N User Exit to automatically display the print preview

Hi All
Does anyone know of way to invoke the Purchase Order Print Preview Option <u>automatically</u> once the user selects the save button as part of the ME21N transaction ?
This is required so that the end user must perform a visual check on the PO just before the purchase order is saved.
We are already the standard print preview button working in ME21N.
Thanks
Donnacha

Hi Donnacha!
Pravat pinned out the main problem: when you want to display something before saving, then it's anything else but not the printout of the PO. The printout goes for the saved values - but you require a display before saving. So you have to develop a complete own display (which can be done of course).
Regards,
Christian

How do I...Mimic Replacement Path with Query using Customer Variable Exits?

Hello SDN:
We are on BW 3.5 SP16.
We are currently using a replacement path Query(RP) with variables
to populate a variable in another Query(T).
The problem we are having is with performance.
The entry of variables in replacement path Query(RP) is optional (This is necessary there cannot be required values)
When results from Replacement Path Query are small performance is fine. (e.g. 10 seconds)
When results from Replacement path query are large performance suffers. (e.g. 1+ minutes)
Users are free to leave the replacement path variables empty resulting in a large set of data to be replaced. This is the worst performance case.
We would like to discover a way to conditionally execute the replacement path query. That is if users do not enter values for the replacement Query(RP) variables do not execute the replacement path query(RP).
Does anyone know if this is possible within reason and in customer exit space?
We have reviewed the situation from all angles and the requirement for the replacement path FUNCTIONALITY and the freedom for the user to leave variable values blank remains.
I've been searching and reading SDN and SAP notes for about a week and do not find threads which address this situation.
We are also exploring Customer variable exits to mimic replacement path functionality
(different topic subject="How do I...Mimic Replacement Path with Query using Customer Variable Exits?")
Any help will be appreciated
Many thanks

My appologies-I posted this message with the wrong subject. I will repost it with appropriate subject.

JUMP (RSBBS) from a query on a transaction(local)

Hi,
Can You help me ?
I want to do a jump from a query on a transaction RSDMD (on local system).But particullary, I want to put in parameter the data (doc number) with wich I jumped.
So How I have to define the assignement detail in RSBBS for the transaction RSDMD?
Because, for the moment I have a popup where I must fill the name of my charactéristic and after the number of my doc number (for example), and it's with the doc number that I do my jump.
But, I don't want to fill characteristic and doc number, I want that it's automaticaly...
Thank you for your help...
Carine.

Calling the RRI with a transaction or an ABAP/4 Report as the receiver is done with the RRI
from the SAP NetWeaver Application Server. This is possible in an ERP system, a CRM
system or within the BI system. The selections are prepared by the BI system that does not
recognize the transaction or the report. The assignment is transferred from the RRI of the
SAP NetWeaver Application Server using inverse transformation rules. There must also be a
complete chain from the DataSource of the source system to the InfoSource, through
transformations up to the InfoProvider. This does not mean that data absolutely has to be
loaded using this chain. If this chain does not exist, the RRI cannot transfer the selections to
the source system. Calling the RRI only works for fields with dictionary reference. For ABAP reports, this means that the parameter has to be PARAMETERS param LIKE <table_field>
For transactions, this means that the Dynpro has to have a dictionary reference. Not every
transaction can be called with the RRI of the SAP Application Server.
These are the steps to do this
If you want to jump from a Web application to a transaction or ABAP/4 report using the
RRI, an ITS for the target system has to be assigned beforehand.
● The value of the input field to be supplied must be known at the time of the jump (for
example by entering a single value on the selection screen of the sender or by the
cursor position at the time of the jump).
● Sender and receiver fields that correspond to one another generally must link to the
same data element or at least to the same domain, otherwise the values cannot be
assigned to one another.
● The assignment of sender and receiver fields must always be a 1:1 assignment. For
example, the transactions called from the start screen cannot have two input fields of
the same data type. Then it is not clear which of the fields is to be supplied, which
means neither of them is supplied.
● There has to be a complete chain from the DataSource of the source system to the
InfoSource, through update rules up to the target.
Proceed as follows after you have created the sender-receiver assignment as described
above.
1. As the type, choose Table Field. The columns Field Name, Data Element, Domain and
Set-/Get Parameter become input ready.
2. Specify the field name, data element, domain and parameter ID for the receiver
transaction. You need to know this information because input help is not available. You
can usually find the parameter ID in the ABAP dictionary entry for the data element.
If this does not always make jumping to the transaction possible, it may be necessary to
program a short ABAP start program. For more information on how to do this, see SAP Note
number 383077

Problem in changing SAP query ME80FN in transaction SQ01

Hi,
I have added two new fields in list layout of the transaction ME80FN. When I execute this transaction it is executing ABAP QUERY REPORT ME80FN.
I added two new fields in infoset SAPQUERY/ME80FN via transaction SQ02.
Then trying to change the QUERY ME80FN via transaction in SQ01. It is saying locked by some user.
Can any one help me how to resolve this what to be done.
Thanks,
JWala

Hi
I found this in another forum. It is simple to do it:
1. Go to SQ02 transaction (Infoset: Initial Screen)
2. Select or Highlight the Infoset corresponding to the query.
3. Go to --> Query Directory --> (you will see the infoset in the name being displayed) Execute.
4. Select the Query you would want to unlock.
5. Click on Cancel Edit lock button or Edit --> Cancel edit lock or Shift + F6
Done...!!!! Query is unlocked
