How to defined which logical database to use in a function module?

Hey,
I am trying to do logical database in a function module. I need to know where do i go to define which logical database to use? Becuase i get syntax error on my Get statement. The logical database i am trying to use is HR PNP .
Any useful help will be appreciated,
Thanks

I think we can't assign logical database to FM or FG. Because there isn't any option to put the logical database in the FM or FG's attributes.
You must have to create a executable report to have the LDB in use.

How to do data source ehancement by using "Extraction by function module"

I have one customized datasource "ZSOURCE" in R/3, this datasource use Extraction by function module, namely one functiona
module "ZBI_FM_EX"and Extract. struct "ZBI_EX".
Now I want to add one field "ZNEW" from standard SAP table LIKP into extractor "ZBI_EX" and write coding in ZXRSAU01.
Question, could I add new field "ZNEW" into Structure:"ZBI_EX"? Do I need to change anything in functional module "ZBI_FM_EX" itself?
Many Thanks!
rajatina.

Hi Dear,
It is good to write the code in your function module i.e. ZBI_FM_EX. becuase writing the code in ZXRSAU01 include program will affect the loading performance. instead of looping the data two time (one in your FM and again in ZXRSAU01 ), you can get the same will only loop.
Thanks

How to execute the logical database.

how to execute the logical database.

There are two ways of using a logical database - either by linking it with the executable program(specify the LDB name in the program attributes) or by using the function module LDB_PROCESS.
1.Data read by the logical database is passed back to the program using the interface work areas.Use GET statements in the report.
GET events are implemented internally as FORM routines.
2.If you call the logical database using the above function module, the selection screen of LDB is not displayed.It uses special subroutines called callback routines, which are called by the function module and filled with the required data.
Please refer the following link for more details.

There's nothing stopping you from using the generated sequence for something else, however you can NOT override it when doing an insert (as long as you've specified ALWAYS which is the default).
SQL> create table t
2 (some_id number generated as identity
3 ,name varchar2(30)
4 );
Table created.
SQL> select * from user_sequences;
SEQUENCE_NAME
ISEQ$$_91970
SQL> select ISEQ$$_91970.nextval from dual;
             NEXTVAL
                   1
SQL> select ISEQ$$_91970.nextval from dual;
             NEXTVAL
                   2
SQL> insert into t values (99,'smith');
insert into t values (99,'smith')
ERROR at line 1:

How can I know the database is using Cost Based or Rule Based?

Hi all expertise,
How can I know the database is using Cost Based or Rule Based?
If cost based it is using, what methods are need to use to minimize the cost when database is running? And which tables I can see the performance of the database?
Thanks
Amy

how to see database setting ?
use this
SQL> sho parameter optimizer
NAME TYPE VALUE
optimizer_dynamic_sampling integer 1
optimizer_features_enable string 9.2.0
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_max_permutations integer 2000
optimizer_mode string CHOOSE
choose means if table statistics is available then it will use cost
else
use rule based optimizer
for seeing performnace of table use
set autotrace on
and run your query
if it doen't show cost.it means it use rule based
for using cost based
u will calculate table statistics
9i
dbms_stats.gather_table_stats('owner','table');
8i
analyze table <table_name> compute statistics;
hope it will help you

How to query which Tcodes specified user used with one day?

Hi guys:
How to query which Tcodes specified user used with one day?

Hi
You can use transaction code ST03N.
1. Go to tx code - ST03N
2. Under "Workload" you can select your "Instance or Total" so that it expands and shows you Days, Week, Month.
3. If you want to look at the transactions executed for a particular day, lets say, then double click on any day.
4. At the bottom left you get "Analysis Views"
5. Select & expand "User and Settlement Statistics"
6. Double click on "User Profile"
7. On the right side of the window you get a list of all the users
8. Double click on a particular user you want to view the details of.
9. The new screen will display the "Transactions/Reports Utilized by User XXX"
If you wanna track which users executed a particular transacation then follow this:
10. In "Analysis Views" expand "Transaction Profile"
11. Double click on "Standard"
You can view the list of Transactions and Reports.
12. Double click on the Tx Code or Report you wanna check and it will show the Use of it.
This will help you.

Your OS might provide a command to support this question like '"netstat".
Besides, on Unix the pseudo-file system /proc is also useful.

Hi Raj
Function Modules
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the Function Builder.
The Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed.

You can execute function module in SE37ie you can perform the activiites defined in the function module by executing it.
By deleting BOM you mention the FM name in se37 and execute. In some function module it will ask input parameters as developed in the program , you have to give the input parameters and execute.

How to get tables used by a Function Module

Hi,
How to know the tables used by a function module dynamically.
Cuurently im using BAPI_MATERIAL_SAVEDATA in my report program.
I tried FM GET_TABLES to know the tables, but could see only tables used in the report.
Main issue in my case is when im running this update program, could observe different tables being displayed as updated in SM50(Process Overview).Want to clarify as why these tables which are not being used in my report are being displayed in SM50.
So was doubtin weather this FM is using these displayed tables.
Thanks in advance for u r replys.
Regards,
Dedeepya

Hi Dedeepya,
you could use a SQL Trace (tx. ST05) to list all tables affected and operations that realize. Just active the trace, execute FM, and Deactive trace. Then click in "Display trace" and check it.

Pablo
