                       AND aposnr = bposnr)INNER JOIN VBAK AS c ON cvbeln = bvbeln
                                                                   AND cposnr = bposnr).
Modify in the way you want and Just include these codes into the Funtion module you create.
I Hope it my help you.

Search help(f4) for function module input

can we create a serch help for function module input giving process

Hello basichodary,
You can encapsulate the function module within a program. Include the search help in a parameter statement in the calling program and pass the parameter to the function module. For example, suppose you want to have field i_carrid to have a search help. Use the following code.
report call_function_module.
parameters p_carrid type s_carr_id matchcode object demo_f4_de.
call function 'FUNCTION_MODULE'
exporting
i_carrid = p_carrid

How to log input parameters for Function Modules?

Hi,
I need to create a Logging system to trace input parameters for function modules.
The log functionality could be done by developing a class method or a function module (For example 'write_log'), and calling it within each function module that I want to log. The 'write_log' code should be independent from the interface of the Function Module that I want to log.
For example, I'd like to write a function/class method that can log both these functions modules:
Function DummyA
 Input parameters: A1 type char10, A2 type char10.
Function DummyB
 Input parameters: B1 type char20, B2 type char20, B3 type char20, B4 type Z_MYSTRUCTURE
Now the questions...
- Is there a "standard SAP" function that provide this functionality?
- If not, is there a system variable in which I can access runtime all parameters name, type and value for a particular function module?
- If not, how can I loop at Input parameters in a way that is independent from the function module interface?
Thank you in advance for helping!

check this sample code. here i am capturing only parameters (import) values. you can extend this to capture tables, changin, etc.

Will Infoset Query work for Function Module

HI Can someone let me know will a Infoset wuery works for Function module or not. I have 3 tables which i need to extract on, i am building a Infoset Query on 2 tables and using this in my Function Module to join on 3rd table. I have some conditions on 3rd tbale which i need to pull only those records.
When ever i check the syntax it always gives me a message
The type "ZUSERLOGINQRY" is unknown. ( This is my Infoset query name).
Can any one help me on this.
Thanks,
Kris.

HI Pat thanks for responding i havent done this earlier so i am not sure how to declare une code under Infoset Query ---> Extras. I am getting some duplicates in Infoset Query, can you let me know how to clear all those duplicates...
Appreciate you help.

What are the input parameters for Function Module

Dear Experts,
I want to generate a Sales Tax returns report,those fields are not available in my existing Datasources.
For that i want to write a Generic Datasource with Function Module.
audat

vkorg
vtweg
spart
aurat
auart
netwr
mwsbp
kschl zedp(consition type)
kschl zvat(condition type)
ksch zcst(condition type)
matkl material group
Here what are the Input parameters for Function Module.
Thanks in Advance.
Srinivasan.

Srinivasan-
For creating a Generic extractor based on a FM, you first of all need to know what is going to be your structure.. i.e. what all fields you need to pull from what all tables. A functional consultant may help you identify the exact DB tables.
Once you know them, hand over the requirement and the pdf mentioned by Krishna to the ABAP guy, he would be able to take this up further.
Also decide 1st whether you would be using a full load or delta. There is a slight difference in the way they are built.
Let me know how it goes.

Transport of ALE Interfaces for Function Module

hi,
i have a Z function module, Z business object type and z message type identifying ALE interface.
i need to move all the objects from Dev R3 to QA R3. What are the steps involved?
Thanks,
Tirumal

Hi
While creating a Z function module it will ask you for a change request number. attach it to change request and migrate it to Production.
In case your function group to which you assigned this function module is open then the CTS number will by default come in CTS number field if any exists for the function group. You can now migrate your CTS to production.
Now after assinging function module to a CTS you can be sure that your program for function module and FM both will be migrated. For confirmation you can now check attribuutes section in your function module. it will list the SAP program associated with Func mod , function group to which function module is assigned , package and include programs which needs to be migrated. So you only need to attach a CTS and migrate your CTS.
You can create a Change erquest (CTS) in SE01 or SE10 transactions.
Regards,
Amit.
Please reward any help

Enter Ur FM in Identification Field.

Creating Includes for Function Modules

Hi Experts,
Can you please let me know how to create includes for function modules.
I came across this in a standard include program, which was generated by a function library. The includes inside this program where linked to the function modules (when I double clicked on them).
Please let me know how to create it.
Thanks in advance !

Anand Patil.

Hi,
have a look at the code for better understanding
Declaration of Workareas *
DATA: lwa_e1bp2017_gm_item_create TYPE e1bp2017_gm_item_create,
 lwa_data TYPE edidd, " Work area for IDOC

loop at idoc_contrl INTO lwa_control Where mestyp = lc_mbgmcr.
Extract the data from the segments.
 LOOP AT idoc_data INTO lwa_data
 WHERE docnum = lwa_control-docnum and
 segnam = lc_item_create.
*->> Set the tabix of the internal table
 lv_index = sy-tabix.
Move the Material Document Item Segment data
 MOVE lwa_data-sdata TO lwa_e1bp2017_gm_item_create.

*->> set the changed values to the IDOC SDATA
 MOVE lwa_e1bp2017_gm_item_create TO lwa_data-sdata.
*->> Modify the table
 MODIFY idoc_data FROM lwa_data index lv_index.
Clear the Work areas
 CLEAR : lwa_data,
 lwa_e1bp2017_gm_item_create.

here when we write the statment
PERFORM sub_modify_idocdata changing lwa_e1bp2017_gm_item_create and double click on sub_modify_idocdata .
it will create a include with the name "LZDTSINT052F_GPOMS_GMF01 ".
now we can write the FORM ..END FORM In this inculde.like this.

Example needed for function module

kindly provide me an example for function module & let me how to use this function in a report program..Thnaks in advance..

Hi,
GO to Tcode SE80.Create fucntion group.Name should start with z or y.
GO to Tcode SE37.Create function module.Assign it to function group created above.Name should start with z or y.
In change mode,you can top include.This is the place you should put the declarations.
In F01,you need to write the form and U01 you should write the main program.Best way is to take any function module(z*) and follow it.
There are 3 types of fm.
1.Normal fm
2.RFC enabled
3.Update task.
Check this link for RFC.
