This is what happens inside the FM using I_ROLL_BACK:

Question about Function Module ME_PO_PRICE_SIMULATION

Hi experts,
I am trying to solve an issue concerning the importing parameter I_ROLL_BACK of the function module ME_PO_PRICE_SIMULATION.
Inside the coding of the user-exit ZXM06U44 (executed after saving a purchase order) there is a call to the function module ME_PO_PRICE_SIMULATION with this importing parameter set to true. In that case, purchase order is not created. Otherwise if I modify this value into false the order is created appropriately.
Could someone more functional explain me what is the meaning of this parameter. I try to read the documentation but is in German, so I don't understand anything.
Lots of thanks,
Javier

A question about function module

hi everyone,
if i want to know the meaning of a function module and how it work,
for example,function'HRHAP_DOCUMENT_GET_DETAIL'
i must use it,but i don't know its meaning,
what should i do ?
thanks

but,in program,import and export are reverse.
for example:
CALL FUNCTION 'HRHAP_DOCUMENT_GET_DETAIL'

Question about function with in parameters

Hello,
I have a question about functions with in-parameters. In the HR schema, I need to get the minimum salary of the job_id that is mentioned as an in-parameter.
this is what I am thinking but I dont know if it's correct or not or what should I do next!
create or replace function get_minimum_salary (i_job_id in varchar2)
return number
as
begin
SELECT min_salary INTO min_sal
FROM jobs
where job_id = get_minimum_salary(xy);
RETURN i_job_id;
end get_minimum_salary;
thanks in advance
EDIT
Thanks for your help all.
Is it possible to add that if the i_job_id which is the in type parameter does not have a minimum salary then use the following function to register an error:
create or replace procedure insert_error (i_error_code in number,
i_error_message in varchar2)
as
begin
insert into error_table (error_user, error_date, error_code, error_message)
values (user,sysdate,i_error_code,i_error_message);
end insert_error;
This function is basically to say that an error has occured and to register that error, at the same time I need to print out the error using the dbms_out.put_line.
Any ideas of how to do that?
Thanks again

HI
I have made little bit changes in ur code. try this
create or replace function get_minimum_salary (i_job_id in varchar2)
return number
as
v_Min_sal jobs.salary%type=0;---- Variable declaration
begin
SELECT min_salary INTO v_ min_sal
FROM jobs
where job_id = i_job_id;
RETURN v_Min_sal;
end get_minimum_salary;

Important conceptual question about Application Module, Maximum Pool Size

Hello everyone,
We have a critical question about the Application Module default settings (taking the DB connections from a DataSource)
I know that on the Web it is generally suggested that each request must end with either a commit or rollback when executing PL/SQL blocks "directly" on the DB without the framework BC/ViewObject/Entity service intervention.
Now, for some reasons, we started to develop our applications with thinking that each Web Session would reference exactly one DB session (opened by any instance taken from the AM pool) for the whole duration of the session, so that the changes made by each Web session to its DB session would never interfere with the changes made by "other" Web Sessions to "other" DB sessions .
In other words, because of that convincement we often implemented sort of "transactions" that open and close (with either commit or rollback) each DB session not in/after a single HTTP request, but during many HTTP Requests.
As a concrete example think of this scenario:
1. the user presses the "Insert" button. An HTTP request is fired. The action listener is executed and ends up with inserting rows in a table via a PL SQL block (not via the ViewObjects API).
2. no commit or rollback after the above PL/SQL block is done yet.
3. finally the user presses a "Commit" or "Rollback" button, firing the call to the appropriate AM methos.
Those three requests consist of what I called "transaction".
From the documentation it's clear that there is no guarantee that the couple AM istance + DB session is the same during all the requests.
This means that, during step 2, it's possible that another user might reference the same "pending" AM/DbSession for his needs and "steal" somehow the work done via PL/SQL after step 1. (This happens because sessions taken by the pool are always rolled back by default.)
Now my question is:
Suppose we set the "Maximum Pool Size" parameter to very a great number (always inferior to the maximum number of concurrent users):
Is there any guarantee that all the requests will be isolated in that case?
I hope the problem is clear.
Let me know if you want more details.

Thanks for the answers.
If I am right, from all your answers about resource avaiability, this means that even supposing the framework is able to always give us the same AM instance back from the AM pool (by following the session-affinity criterias), there is, however, no "connection affinity" with the connections from the DataSource. This means that the "same AM instance" might take the "a new DB connection", if necessary, from the connection pool of the DataSource. If that happens, that could give us the same problems as taking "a new AM instance" (that is, not following session-affinity) from the beginning, since each time an a new connection is taken (either via a new AM instance or via the same AM instance plus a new DB connection), the corresponding DB session is rolle back by default, clearing all the pending transactions we might have performed before with direct PL/SQL calls bypassing the AM services during the life cycle of our application, so that the new HTTP request will have a clean DB session to start to work with.

About Function module 'PRICING'

Hi experts,
Now My requirement is get all contract condition data. If I don't want to create a new contract to get these condition data, I can use Function module 'PRICING' to get all condition data. But the question is the parameter COMM_ITEM_I is a structure, it only can store a record(single material). If the contract has many item, eg Service + Goods............ How to process this scenario? If you have experience in this, please give me any idea. Thanks in advance!

Hi,
I guess contracts will be found in EKKO, not in VBAK. Correct me if I am wrong.
If I am correct, you can use the BAPI "BAPI_PO_GETDETAIL1". POCONDHEADER and POCOND inporting tables will retrieve pricing information.

About Function module reltate to Enhancement

Hi All,
i need to know about the Usage and purpose of the function module FKK_BP_BADI_UPDATE.
Kindly help me to know about this function module

Hi Venkat,
The function module BAPI_CUBE_GETDETAIL provides you the detials of infocube (including dimension, characteristics, keyfigures etc).
Moreoverthis FM is RFC enabled; so you can call this FM from DEV and pass RFC connection of PROD to get detials of the cube in prod. This compare the structures between DEV and PROD.
Similarly you can use BAPI_ODSO_GETDETAIL from DSO structure comparision across the system landscape.
Thanks

Table that stores information about function module

Hi All,
I know that table TFDIR stores primary information about any function module.
Could anyone tell me where the code of that function module gets stored in?
Also.. If I want to write an ABAP code to read the function module code then what is the best possible solution?
Thanks in advace and any answer will be appreciated.
Regards
Jignesh

Hi All,
Apologies for the same!
The codes are not stored in any table, they are stored as cluster.
To read the code, you can use READ REPORT.
But there you must provide the Include Name For Example , If you want to read the code of READ_TEXT,
READ REPORT 'LSTXDU01'.
You can get this include name inside include LSTXDUXX
Table TFDIR also stores the program name and include number.
You need to truncate first 3 char 'SAP' and append UXX at the end and that will be your program name.
Then we can use READ REPORT!!!

Query about Function Module 'RSPO_RETURN_SPOOLJOB'

Hi all,
     I am currently working on a report that takes the SPOOL NO. for the back ground runned job and passes to the Function module 'RSPO_RETURN_SPOOLJOB' that gives the data in BUFFER after reading this data I am converting it to the excel format and sending it as an attached mail to the specified recepient.
     But the FM mentioned is getting data in weird manner. I am converting it to excel format as we do for the normal internal table data being converted to excel format. But the problem is ragarding the data...
     Is there a way to covert this data into excel format? Or is there any other function Module that converts the data into excel format for the job. If it is there then let me know...
