Uppercase / Lower case Flag in Function Modules

I want the upper case / Lower case flag to be checked active by default when we execute my function module. How can we achieve ?

The checkbox is a part of FM TEST Framework and any changes can't be made to it. Also, while calling through program it will come into picture.
If you want text in specific case
1. Check the domain lowercase property of the data element to be used in import parameters.
2. Use TRANSLATE statement to change case inside the FM.

Case sensitive in Function Module

Hi experts,
we created the custom table and maintaining the data.we saved the data with key as case sensitive which we selected at domain level .we created custom function module in that we have written SELECT statement with where clause .when we are testing the function module in SE37 ,if i enter lower case value in the exporting parameters and after executing the F.M the input values are changing into upper case. so i am getting wrong data.please help me.

Hi Vinod,
I have given interface import parameter reference Z-data element which is already used in the Z-table.For example In the FM
iv_name type zz_name.
zz_name is a data element and ZZ_NAME1 is domain name and where i selected the check box as lower case and upper case.
Please any one help me.

Uppercase / Lower case

Dear Master's,
I created editable alv,when i press save from report data get saved in table as UPPER case.But i want data will save as UPPER/LOWER case. Please help
Thanks & Regards
Atul Singh

Hi Atul,
Please check the data type of the fields that you are using. If it is a character type that does not allow lower case letters then data would surely get converted to upper case.
So, instead, try to use a field type for which the 'Lower Case' checkbox in its domain is selected.

Uppercase lower case issue..

I am fiinding this throughout all the oracle stuff.
If I create a view or stored procedure, it always returns the column names in uppercase...
This is an issue, becuase some of my code uses keys in grids that are case sensitive.
And my app has to work with both MS SQL and Oracle..
So the view listed below, returns the column names in uppercase instead of the case I have specified..
Is there any way around this?

Function module not working when used with 'In Background Task'

hi,
this is my code
call function 'Z_IBD_FILL_ZINETACT'
              in background task
              destination 'SAPD220125'
              tables
                  it_net1 = it_net1
                  it_net2 = it_net2
                  it_net3 = it_net3 .
when this code is executed i am not getting any data in my internal tables i.e it_net1, it_net2, and it_net3
but i changed this code see the below code
      call function 'Z_IBD_FILL_ZINETACT'
             in background task (THIS IS COMMENTED)
              destination 'SAPD220125'

now i am getting data into my internal tables
can any one tell me what can be the problem and how to solve it in my case
its very urgent

Hi,
Pls. go through the docu..
CALL FUNCTION
Variant 5
CALL FUNCTION func IN BACKGROUND TASK.
Additions:
1. ... AS SEPARATE UNIT
2. ... DESTINATION dest
3. ... EXPORTING p1 = f1    ... pn = fn
4. ... TABLES     p1 = itab1 ... pn = itabn
Effect
Flags the function module func to be run asynchronously. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and the next COMMIT WORK executes it in another work process.
Note
This variant applies only as of Release 3.0, so both the client system and the server system must be Release 3.0 or higher.
Note
qRFC with Outbound Queue
This is an extension of tRFC. The tRFC is serialized using queues, ensuring that the sequence of LUWs required by the application is observed when the calls are sent.
For further information about qRFC, refer to the Serialized RFC: qRFC With Outbound Queue section of the SAP Library.
Addition 1
... AS SEPARATE UNIT
Effect
Executes the function module in a separate LUW under a new transaction ID.
Addition 2
... DESTINATION dest
Effect
Executes the function module externally as a Remote Function Call (RFC); dest can be a literal or a variable.
Depending on the specified destination, the function module is executed either in another R/3 System or as a C-implemented function module. Externally callable function modules must be flagged as such in the Function Builder (of the target system).
Since each destination defines its own program context, further calls to the same or different function modules with the same destination can access the local memory (global data) of these function modules.
Note
Note that a database commit occurs at each Remote Function Call (RFC). Consequently, you may not use Remote Function Calls between pairs of statements that open and close a database cursor (such as SELECT ... ENDSELECT).
Addition 3
... EXPORTING p1 = f1 ... pn = fn
Effect
EXPORTING passes values of fields and field strings from the calling program to the function module. In the function module, formal parameters are defined as import parameters. Default values must be assigned to all import parameters of the function module in the interface definition.
Addition 4
... TABLES p1 = itab1 ... pn = itabn
Effect
TABLES passes references to internal tables. All table parameters of the function module must contain values.
Notes
If several function module calls with the same destination are specified before COMMIT WORK, these normally form an LUW in the target system. Calls with the addition 1 are an exception to this rule - they each have their own LUW.
You cannot specify type 2 destinations (R/3 - R/2 connections).

API - BAPI , RFC Function module to validate user id and password

Hi,
Can anyone provide me with the function module to validate the username and password of the user of the back end R/3 System.
Best Regards
Sid

Use function module SUSR_CHECK_LOGON_DATA. You need to provide auth_method (P for password check), userid and password.
Be careful when you execute the function in test mode because it converts the input into upper case hence if you have lower case characters in your password it will return with invalid password. If you pass the lower case into the function in a program everything is fine.

Michael

Function module table returning empty rows but export data is getting

Hi,
I am executing function module through JCO after setting importing parameter and when i retrieve the table i get table with empty data 0 rows but i am able get export parameter data . when execute the same function module in abap through sap gui i get table containing 5 rows. what may be the problem. please find below code
      function = getDefaultJCoConnection().getJCoFunction("ZCRM_ICSS_PROJ_CUST_USR");
            function.getImportParameterList().getField("USER_ID").setValue("MLDL010");
            getDefaultJCoConnection().execute(function);
            exportTable = function.getTableParameterList().getTable("PROJCUSTLIST");
            int rowsNumber = exportTable.getNumRows(); // companies table number of rows
            log.error("rowsNumber----"+String.valueOf(rowsNumber));
try
     if (rowsNumber > 0)
     int i = 0;
     do
     tempString="table valuesZCOMP_ID"(String)exportTable.getValue("ZCOMP_ID")"ZCOMP_SPC-"+(String)exportTable.getValue("ZCOMP_SPC")
                 + "table valuesZCOMP_DESC"(String)exportTable.getValue("ZCOMP_DESC")"ZPRICE-"(String)exportTable.getValue("ZPRICE")"---" ;
     log.error(tempString);
     while (exportTable.nextRow());
     catch (Exception th)
     log.error("The following error occured: while retrieving table values ", th);
Do you have any idea where may be the problem
Regards,
Pavan
Edited by: Pavan Reddy on Apr 10, 2010 4:46 PM

Hi Pavan,
This could be the case. The function module might be expecting a value converted into its format.
By this, I mean that the function module might be expecting 0012345678 for 12345678 (Where data element of the ID is of type CHAR 10 ).
Please check if it is so.
Best Regards,
Kris.

Is it necessary to use the standard function modules always?

Hi All,
Suppose i can retrieve the BUSINEES PARTNER ID from the table BUT000 with the help of 'BP_GUID' field through a select query statement.
Now is it necessary to use a standard function module to retrieve the same data. what about the performance? which is the better solution. to implement our own code or to use the function module available.
Please someone clarify me about this issue.
Regards,
Sharry.

If you'd ask the question in general it's obvious that there is no good answer as it always would depend on the circumstance. However, as you've posted your question in the performance tuning forum, let's look at your question in this context first. I think it's fairly safe to say, that in almost 100% of the cases a standard function module will not be as fast as any well implemented and custom tailored code. If in doubt, just try reading the code of the function module you want to read; most likely you will find lots of unnecessary fluff in there, often they read data that you don't even need.
And as far as buffering is concerned, that can also be an issue. E.g. let's say you do a massive read of distinct business partners and you only need the data once for each partner. Obviously buffering is silly in this case and it might even slow down your program, because the implemented buffering is not necessarily well implemented. I've come across a few cases, where the buffer tables where standard tables with no efficient read access (so no sorted table or hash table) and once tons of data were buffered, it actually took a moment to look up if the record already was buffered (just to find it wasn't there yet).
Now most of the times this slowdown is not an issue as the lookup is still fast compared to the (usually) prevalent database accesses with their slower IO timing. But another factor to consider is memory consumption and why buffer data in memory (and waste it), if you can't use the buffer anyway? So when I do use standard function modules, I usually try to see what they retain in global memory, to better understand if I need to call some initialization/clearing/refresh function...
Note also that often you need to process lots of data, but don't find a standard function module for "mass access", so you need to read your object one by one. Obviously that's another good candidate for implementing your own queries, where you can process the data in packages.
So what might be the reason to use a standard function module? Well, often it's required because the logic is so complex that it would take you too much time to implement it (not to mention that we often simply don't know all the logic that's coded in there). Another advantage is that you might get independent of the data model. E.g. for IDoc interfaces SAP switched in some release the tables where the data is stored. So if you had coded your own queries to get IDoc data, they wouldn't have worked after this particular release upgrade. The standard function on the other hand, checks both the old and new tables, so by using it you would have been fine.
The one major caveat I'd give though is to always check whether the function module is released or at least documented to some degree. I.e. if it's not released, SAP won't support it and does not guarantee that the interface or logic stays the same. In my experience lots of functions I do want to use are not released (or documented), but I will still use them because they seem to be the best alternative in certain scenarios.

Difference between Function module in Update task

Hi folks,
What is the difference between
1. A function module calling in 'update task'( if attributes not set for update mode).
2.A function module's attributes set to update mode, but while calling not specified 'Update task'.
Please clarify this doubt.
Thanks in advance.

It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task. Update function modules must be flagged as such in the Function Builder
The return value is not set.
Addition 1
... EXPORTING p1 = f1 ... pn = fn
Effect
Values of fields and field strings specified under EXPORTING are passed from the calling program to the function module. In the function module, the formal parameters are defined as import parameters. In the interface definition, default values must be assigned to all import parameters of the update function module.
Addition 2
... TABLES p1 = itab1 ... pn = itabn
Effect
TABLES passes references to internal tables. All table parameters of the function module must have values.
Note
With update function modules, both import parameters and exceptions are ignored when the call is made.

Types of function Modules

What are different types of function modules ??
Please tell in detail about Normal function modules and RFC enabled functional modules ?
I have searched other threads also but did not get the enough descriptions of the same.
Please respond !

Hi Shreya.
Basically, RFC function modules deal with remote function call which means those ABAP programs can be run/executed from a remote SAP system.
The best example for implementing the RFC Function modules are the BAPIs.
In case of normal function module, The call is made within this SAP system.
RFCs are more often used to establish link between two servers.
Normal function modules provide linking localy that is with the same SAP server/environment.
The calling of RFC function module depends on different client-server specifications.
In case of normal one, the call is same client related call.
Hence, In short RFC for Global
and Normal Function module for Local.
Good Luck.

IDOC error 51- Function module not allowed:

Hi,
I am getting following error in IDOC inbouond.I verifyed all parameters mentioned in error.
Issue still not resolved.
When debugged from WE19 this issue dosnt arise.
Kindly guide.
Function module not allowed: ZIDOC_INPUT_MATCLASS
Message no. B1252
Diagnosis
The function module ZIDOC_INPUT_MATCLASS and the application object type BUS1001 which were determined are not valid for this IDoc.
Procedure
1. Please check that the process code in the inbound partner profile is correct.
2. If this is the case, you should check the ALE inbound methods ALE inbound methods for the process code and see whether the specified function module and application object type are correct.
3. If this is also the case, then the function module and the application object type are not permitted for the logical message type, message variant, message function and basis type that are contained in the IDoc control record. You should check whether the correct values have been assigned to these fields in the control record. If they do have the correct values, then the assignment to the function module and the application object type needs to be maintained.

Hi,
Check in WE42, for the process code, you have assigned this function module and given the correct process code in the partner profile.

Idoc error 51 - "Function module not allowed - APPL_IDOC_INPUT1'

Hello everyone,
We are uploading GL balances from legacy to SAP using the LSMW Bapi
object - bus6035
method - post
message type - ACC_DOCUMENT
Basic type - ACC_DOCUMENT03
When we run the lsmw, idoc is created, however with an error 51 saying
"Function module not allowed - APPL_IDOC_INPUT1'
The partner no. is the logical system (the system on which the lsmw is executed)
In the partner profile, we have defined this as LS. In the inbound parameters, we have defined message type = ACC_DOCUMENT, the process code is APL1 and the corresponding function module is - APPL_IDOC_INPUT1
Please let me know if we are missing something or doing anything wrong ?
Since the data in the LSMW will be read frmo a file on the presentation server, do we need to have a port configuration for the same ?
Thanks,
Sushil Joshi`

Documentation of Function Modules and Class Methods

Hi
    I would like to know the function modules that handle the documentation of function modules and class methods.Is it possible to assign the same documentation of a function module to a method as method documentation?
    Are these documentations stored in some system tables?
Thanks in advance,
Hema

The documentation text is stored as Standard text.
you can see these details in the function module->
goto->documentation->
you will now see a screen, there GOTO->HEADER.
YOU will see a screen with the below details.
Text Name       Z0MM_SCM_FNC_EVCOR_DELIVERY
Language        EN
Text ID         FU   Function module
Text object     DOKU       Online Documentation
in this case TEXT NAME = FUNCTION MODULE NAME.
These details are stored in STXH &STXL . But you can use select from these tables. you have to use READ_TEXT to read the documentation to the program.

Copying function module (FM) with funtions

Hi all,
I'm trying to copy one function module (FM) called Z1 to another called Z2. Z1 contains lot of functions stored within its includes. After copy functions are referenced to original's includes of Z1. I need them to be copied as well to new includes. Would I try to copy it to diffrent function group or to copy whole group under new name?
Thanks
Martin

Hello Martin,
I must agree with Ramesh. Copying Function Modules can be a very messy job. In my experience, in case of complicated function modules, it's better to copy the function group and then delete the stuff that's not required.
