Default values in tables for function module

Hi,
We've created a function module and it is their requirement to have a default value for the tables in the FM? How do we do this? Cause if it is just an import parameter there is a column for default values, but for tables there is none. How do we code this?
Thanks.

Hi,
In the start of the function module you can check the table and set your default values.
FUNCTION ...
"Check whether the table is initial
"Do not override the value passed by the user
IF itab[] IS INITIAL.
itab-field = 'DEFAULT'. "Set your default value
APPEND itab.
ENDIF.
- - - Your functionality

Table for Function modules - Changed date & Changed by.

Hi Experts,
Help me to get Function module changed date & changed by.
For programs we can get the mentained information in TABLE : TADIR.

Function Modules change history can be retrieved from table TRDIR.
Function Module stores a program Include in table TRDIR.
The details of the Function Module can be found in Attributes-->general data tab in the Function Module.
You need to pass the Include which correponds the FM.
Hence you can find the Log changes.
Hope this helps.

DB table for function module extractor

I would really appreciate any comment or suggestion about this topic: Function module based extraction. I opened this thread on the BC & Extractors forum, but unfortunately none has given me any feedback yet.
Thanks & Regards, Davide

So none see any advantage with storing the extracted data in a materialized DB table, before transmitting the records to BW. Can I infer it's probably not a good idea wasting time with an additional massive write operation?
Cheers, Davide

ConfigurableVariant materialclassification values-Tables or Function module

Hi All,
We have a configurable material (say M01) with Class type 300 and have various characteristics assigned to the class. We have a variant material (say 234567) assigned to the configurable material M01. In the Characteristic values assignment screen we assign a value (say 123) to the characteristic Paper material.
Now my question is how to get the link between characteristic Paper material (123) and variant material (234567). We have a transaction CL31 where you can get variant material if you give the paper material characteristic. I want to know if there is any table or Function module available to get the link.
Appreciate your reply.
Thanks,
Srinivas

this type of setting is in the item category settings from sales order.
if your selction criteria (values ) matches with the exiting material code which got same charectristic valeus as that of selection in Sales order, that material will be replace by exiting material code.
you can see that setting in spro>Sales and Distribution>Sales>Sales Documents>Sales Document Item-->Define Item Categories here indicator variant maching should be ticked and Mat. Variant Action as 2 or 4.

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.

Populate final table in Function module

hi,
please tell me the way to populate the final intenal table in function module, form four of the other tables with the corresponding data. i'd like to know how to move fileds of one table to other with maximum performance, can i user move-corresponding for the same.........

hi,
There are two ways to move the data ....
1. You can loop through the table data and move the corresponding field on to your final internal table .
2. You can directly assign the table value ...but remember the stucture of both the tables should be same.
i.e,
itab1[] = itab[].

Do one thing, Just in the tables tab give the name of the table and don't write anything else. no TYPE and no ANY.
Hope it will resolve issue.

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.

Vendor-Customer balances in group currency-table/structure/function module?

Hi All,
Which table/structure/function module can be used to get balances for vendors and customers in group currency? We just wnat to extract balances in group currency so FBL1N and FBL5N are not options. Is there any SAP report which can provide these balances for both vendors and customers?
Thanks and regards,
Pinky

Hi Pinky,
I came across one report S_ALR_87012079 - Transaction Figures: Account Balance, Program RFSRRCUA, which extracts Account Balances of Vendor. Once the report is executed, you can do Currency Translation from one currency to different currencies. In the output screen, in the Top Menu, select 'Settings -> Currency' and you can convert to another currency. I am not sure, if this helps you. If this helps, kindly update your comments here.
Thank you.

CAPP - standard value calculation origin 9 function module CE22.

Dear,
I've a project where i need to calculate standard value time based on multiple and various criteria. (standard price of a all components assigned to one operation)
I've seen that it should be possible to calculate a characterisitic value based on a function module in a method. (characterisitic value origin 9 - function module).
When i try to use the method with a function module I get a dump. ( CALL_FUNCTION_PARM_MISSING).
I don't find any documentation on the usage of a function module. as origin for CAPP.
Could you please help me ?
Br,
Daniel.

There are so many threads and documentation available on the same..Please search the same.
Moreover if you share the error then it would be easy to know the exact problem
