Use of Logical Database in function module

Hello Experts,
Is there a way of using logical database and Get enent inside a function module.
I am trying to create a RFC for HR module and need this badly. Any help would be highly appriciated.
Thanks,
Gregory fernando

This fm will work fine with all LDBs including PNP
Have you checked the fm documentation ?

How to use a Logical Database in Function Module.

Hi Experts,
I want to use a logical database in a Function Module to fetch data from a standard SAP table into a Internal table for certain filter conditions.
How can I get get this done????
I called LDB_PROCESS FM in my FM, but I could not figure out how to store the extract in my IT table since we cant use GET in FM.
Please provide me a sample code if possible.
Thanks in Advance,
Alex.

Hi,
i had an example program like this ,in this i want to get the data using pnp logical database with 5 fields in an interface program.
data: begin of it_final occurs 0,
        pernr like pa0002-pernr,
        vorna like pa0002-vorna,
        nachn like pa0002-nachn,
       usrid like pa0105-usrid,
       usrid_long like pa0105-usrid_long,
       end of it_final.
get pernr.
clear : p0000,p0002,p0105.
rp-provide-from-last p0000 space p_date p_date.
if p0000-stat2 = '3'.
    v_pernr = pnppernr-low.
else.
    reject.
endif.
*---Get employee pernr, First name ,Last name into final table
rp-provide-from-last p0002 space p_date p_date.
if pnp-sw-found = '1'.
   it_final-pernr = p0002-pernr.
   it_final-vorna = p0002-vorna.
   it_final-nachn = p0002-nachn.
else.
*---Error message if not infotype 0002 maintained
T_ERROR-PERNR   = pnppernr-low.
CONCATENATE TEXT-EMI '0002'
INTO T_ERROR-MESSAGE SEPARATED BY SPACE.
APPEND T_ERROR.
CLEAR T_ERROR.
endif.
**--Get SYSTEM USERNAME to final table
rp-provide-from-last p0105 0001 p_date p_date.
if pnp-sw-found = '1'.
    it_final-usrid = p0105-usrid.
else.
*---Error message if not SYSTEM USERNAME maintained
    T_ERROR-PERNR   = pnppernr-low.
    CONCATENATE TEXT-003 '0105'
    INTO T_ERROR-MESSAGE SEPARATED BY SPACE.
    APPEND T_ERROR.
    CLEAR T_ERROR.
endif.
**--Get Email ID to final table
rp-provide-from-last p0105 0010 p_date p_date.
if pnp-sw-found = '1'.

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

Better alternative to header lines, use of logical database, field-symbols

Hello experts,
I am wondering if theres a better and faster alternative than declaring a header line for an itab. are work areas faster?
What is the use of logical database? can you please give me an example on how to use it in reports.
how do I use field-symbols? I am confused on how it works.
P.S. I recently installed SAP netweaver preview abap edition
in my home PC and I am wondering if I could practice BDC, user exits, etc. If so, how?
Again, thanks for all your help since I'm kinda new to ABAP.

I always use this...It uses header lines, but at least is smaller -:)
DATA: BEGIN OF MY_TAB TYPE STANDARD TABLE OF BKPF WITH HEADER LINE.
For logical databases, you can check my blog...I always use LDB for HR programs -:)
<a href="/people/alvaro.tejadagalindo/blog/2006/02/19/how-to-deal-with-hr-payroll-reports:///people/alvaro.tejadagalindo/blog/2006/02/19/how-to-deal-with-hr-payroll-reports
LDB's provides a lot of information, because they gather it from a lot of different tables...
A Field-Symbols is like a pointer in C++, like an alias for a variable...Here's a small example...
REPORT Z_ATG_DUMMY.
FIELD-SYMBOLS: <F1>, <F2> TYPE I.
DATA: TEXT(20) TYPE C VALUE 'Hello, how are you?',
 NUM TYPE I VALUE 5,
 BEGIN OF LINE1,
 COL1 TYPE F VALUE '1.1e+10',
 COL2 TYPE I VALUE '1234',
 END OF LINE1,
 LINE2 LIKE LINE1.
ASSIGN TEXT TO <F1>.
ASSIGN NUM TO <F2>.
DESCRIBE FIELD <F1> LENGTH <F2>.
TEXT = 'CHAU'.
WRITE: / <F1>, 'has length', NUM.
WRITE: / TEXT, 'has length', NUM.
ASSIGN LINE1 TO <F1>.
ASSIGN LINE2-COL2 TO <F2>.
MOVE <F1> TO LINE2.
ASSIGN 'LINE2-COL2 =' TO <F1>.
I just can't install SAPNWSP...I only got MiniSap...But I got all the development enviorment...Don't know about the User-Exits...Actually I don't think so...Because those "mini" systems doesn't come with any functional module.
Greetings,
Blag.

Parallelization is not happening using asychnronous RFC in a function module

A BW data source ZTEST
has been created based on a function module ZTEST_FM to pull the
data into BW system from R/3.
(Have checked the parellel jobs running in SM66 transaction).
Inside the function module, an RFC function
module ZTEST_RFC1 has been called asynchronously to implement the parallelization
to improve the data extraction time into BW system.
Note: In this scenario asynchronous
RFC is used to implement the parallel processing.
The logic in the function module is as follows.
Function module ZTEST_FM Logic:
Fetch data from HRP1000 table into an internal table IT_HRP1000 for
OTYPE = ‘TN’.
Loop at IT_HRP1000 into work area (WA).
Call the RFC asynchronously by passing OBJID,OTYPE and ENDDA,
Calculate SOBID which is the required output field from the RFC
function module.
Populate the results into final internal table E_T_DATA.
The output structure contains the following fields.
OBJID
BEGDA
ENDDA
SOBID
Could you please give us some suggestions, to implement the parellel processing using asychronous RFC in this scenario.
Would appreciate your help.

Your RFC call looks correct. For collecting the result you will need to code the callback routine Write_E_T_data. Inside the callback you can use the statement
RECEIVE RESULTS FROM FUNCTION ZFHLS_EX_TNM_ACADEMY_RFC1 IMPORTING <parameter list>
to retrieve the calculated result. For the declaration of the callback routine I recommend
FORM Write_E_T_data USING iv_name TYPE c.
The parameter iv_name containing the name of the RFC task turned out to be mandatory in my tests.

Can i use Two DSO 's in Function module

hi experts,
Can i use Two DSO 's in Function module .That FM is used for Layout
I actually want to fill one DSO Refering the Data in Another DSO.
Regard
Naresh.

In the first way the DSO's are usually called shared libraries or DSO libraries and named libfoo.so or libfoo.so.1.2. They reside in a system directory (usually /usr/lib) and the link to the executable program is established at build-time by specifying -lfoo to the linker command. In the second way the DSO's are usually called shared objects or DSO files and can be named with an arbitrary extension

How to use OWN logical database

Hi all,
hope somebody can help me.
I copied a standard logical database (FPMF). The program which I use and have modified is also copied from standard.
How can I assure that the program use MY logical database instead of the SAP-One?
In my case I have some get statements. And these get statements all refer to FPMF and not to my copied database.
Do anybody what's the probelm?
Cheers
Philip

Yes, I know. And I am not happy with this solution.
But I didn't see another way for my issue.
Thank you very much.

Why we should use Macros if we have function Module

Why we should use Macros if we have function Module and what is the Advantage of Macros than function Module

Put it this way... if you have blueprints for a car you wouldn't want to produce only one car, would you? You would want to produce as many as needed. In another example, you don't want to be able to use only 1 window in Windows. Each window has common features but have different values. That's the purpose of non-static entities
However, there are instances that you want to have only one value for something. That's when you use static entities.
Get it? =)

Generic Extractor built on an infoset which uses a logical database

Is anyone aware of any performance issues when building an infoset generic extractor which uses a logical database as the source? Also would anyone also be aware the process of collecting data for extraction? Thanks

Hi Arun,
Thanks for this - I have been informed that there are issues with a small subset of data and I just wanted to get an idea if the steps that would be carried out be the same if the generic extractor is built on table joins or logical data base or does the latter actual carry out say some pre processing steps

Pls explain me the use and purpose of following Function modules

pls explain me the use and purpose of following Function modules
1. G_MAX_PERIOD_AND_OFFSET_GET
2. DEQUEUE_E_TABLE
3. FI_COMPANY_CODE_CHECK
4. G_PERIOD_GET
5. alv_display_function
6. G_SET_GET_ID_FROM_NAME
thanks ,
phyrose

1. G_MAX_PERIOD_AND_OFFSET_GET
For given No. of period & periods it gives the offset
2. DEQUEUE_E_TABLE
To Unlock the table records
3. FI_COMPANY_CODE_CHECK
To validate Company Code

4. G_PERIOD_GET
Returns no. of Posting period & Special period for give company code, posting date & ledger
5. alv_display_function -
No such FM exists

6. G_SET_GET_ID_FROM_NAME - Use this module to derive the internal set Id from the name that appears on the user interface, for example, in order then to import the set (see the function group documentation).
The function module first determines a candidate list of sets based on the set name and the class that might have been specified that could match the set name. The class can also be masked (e.g. 000+ for all FI-SL sets, including dynamic sets).

How to make use of logical database in reports?

hi,
I am working on a Cash Flow Forecast report, which requires the usage of 'PSJ' Logical Database for the selection screen with Profit Center(PRCTR) as one field and the other field being Period ( in MM/YYYY format).
I have not worked on Logical Database before. Since, its for the first time I am working on LDB, I require help on it.
How to proceed for this, can someone help me with it?
On receiving further inputs, I will proceed and might come up with some more queries.

Anyone have used FTI_TR_COMM_DEAL_EXP logical database?

Hi Experts.
I need to use FTI_TR_COMM_DEAL_EXP (TRM module) logical database in Report. I am very newbie using Logical Databases. Can anyone help me, please?
Thank you.

Hi Rochard
Try running
catalog.sql, catproc.sql and catpatch.sql. I think that should solve your problem.
It looks like even the new database created should be run with catpatch.sql after you upgrade you sfotware from your base version 9.2.0.1
thanks

Using PNP logical database in report

Hi i'm using the PNP logical database in my report, and i want to hide all fields in the 'Period' frame.
is there any way to do it automatically or is it necessary to hide them one by one??
Thanks in advance.

If you can put them all in the same screen group, you may be able to do this. But you might run into problems when you re-generate.

Error 101 using fp_job_open, fp_job_close in a function module

I have earlier made a program generating a pdf used for printing. Used fp_job_open -> Call function xxx -> fp_job_close. This program works fine.
Now I want to make a function module to generate this pdf for higher reusability, but when I call my generated FM its return sy-subrc = 1 and sy-msgno = 101. As far as I have investigate this error means "Job already open".
I tried to comment out the call to the fp_job_open and fp_job_close, but then I have no possibility to mark the ls_outputparams-getpdf = 'X' and ls_outputparams-nodialog = 'X'.
Any ideas anyone?

I am not sure if this is the right forum for this question. Maybe: ABAP Developmnet -> Form printing [Output Management; is more proper?
