Func Module : LDB_PROCESS and Logical Database ADA

Hi All,
How to get 'ANLB' data from logical database 'ADA' using the
function module 'LDB_PROCESS'?
Is there any other way to done this without getting into SELECTION SCREEN of this LOGICAL DATABASE?
With Thanls & Regards,
R.Nagarajan.

Hi,
Using LDB_PROCESS will made all the fields of this LDB available to you......this is the way ..you can use n number of LDB's in your program apart from the one that u mention in Program attributes....
for more details and Function call..use..

Multiple calling logical database ADA

Hello,
I need to call logical database ADA two times in my program. I use calling logical database using LDB_PROCESS function module. I need to call LDB for depreciation areas 01 and 60. If I call second time, I get exception LDB_NOT_REENTRANT. I found, that for multiple calls of LDB, there should be LDB_PROCESS_INIT subroutine in logical database proram. In this case, program is SAPDBADA and in this program, LDB_PROCESS_INIT is missing.
Could you pls. help me, how to call ADA logical database two times?
Thanks&regards,
Jirka

The exception LDB_NOT_REENTRANT means: The logical database is not prepared to accept several successive calls within a transaction. So obviously you can't use LDB_PROCESS for your purpose.
Perhaps your goal is possible if you use a sequence of commands
GET <ldb_node_1>.
GET <ldb_node_1> LATE.
GET <ldb_node_2>.
GET <ldb_node_2> LATE.
etc...
where ldb_node_1, ldb_node_2, etc... are some nodes included in logical database ADA. As I am not familiar with this particular LDB I can't tell which nodes are required to achieve your goal.

Asset Reporting - Copying Logical Database ADA

Can you please assist with the following query? Im trying to include the following standard R3 ffields within standard R3 reports AR01 (Asset Balances) & AR18 (Depreciation Simulation):
                                Table            Field Name            Data Element
Serial Number            ANLA            SERNR                AM_SERNR
Inventory Number       ANLA            IVNR                   INVNR_ANLA
To date I have been unsuccessful in my endeavours.
I have been discussing with an ABAPer and have been discussing the creation of Z transactions to give me the information Im looking for.
Im looking for help, assistance and expertise whether the following would be recommended or even technically feasible.
·     Is it possible to copy logical database ADA to say ZADA (if yes how would I or the ABAPer go about this)?
·     Is there a way to link existing R3 reports to the new logical database
As the majority of the R3 reports appear to be linked to ADA the aim is to amend this once and not require creating lots of Z reports.
Any help you could provide would be greatly appreciated
Best regards,
Paul

Hi Paul,
this is strange, what release are you on?
I have just checked AR01 on ECC 6.0, and it offers everything you need. On the selection screen of AR01, you can add selection criteria on both Serial number and Inventory number. Plus, you can display both fields in the ALV list.
The data may be stored on table ANLA physically, but the logical database ADA is using a structure (ANLAV) instead. Both SERNR and INVNR are available in that structure. On the selection screen, you have to use the Dynamic selections button. And in the ALV list, you simply add the 2 columns, best idea wold be to save it as a variant for future use.
Anyway, logical databases can be copied in SE36, you simply have to press the Copy button The more critical issue is how to link standard reports to the new LDB. The answer is, no way. Instead, you should copy some of your favorite standard reports, and change the LDB in the copies.
But, I really do not think you need this, as ADA can provide you with the information required out of the box.
Hope that helps, points welcome

Problem with logical database ADA

I am trying to create query with asset values and master data fields but when trying to use logical database ADA I am getting error No component exists with the name "VALUE0". .InfoSet Cannot be Used for InfoSet Query.
Does anyone have an idea about such problem?

Hi,
The message "No component exists with the name "VALUE0"" created when you omit to edit the field group only happens if no field is assigned to a fieldgroup, it should not appear if you add at least one field to a field group.

Changing logical database ADA

Hi,
I have a requirement to change the selection screen of a report. I need to remove one field and add another field in place of it. Now the report selection screen is getting retrieved from logical database ADA. How can I achieve the addition of field in logical database. Do I need to copy the existing logical database to a new one or is there any other way of achieving this ?

Thanks for the reply Shiba. For that particular problem, the business wants to not have to use the dynamic selection, and just have KNA1-REGIO and KNB1-BUSAB as regular select options. Like I said as well, I did find DD_BUSAB which I can use for KNB1-BUSAB, but KNA1-REGIO is still a problem.
Right now I just use a CHECK statement and filter kna1-regio after the GET kna1 statement.
Thanks again,

Adding user fieds to logical database ADA - solution?

Hi,
I have problems with adding (by append structure) my user fields (which are added to standard SAP table ANLA) to logical database ADA which is used in AM reporting.
I have found this solution:
Thru SE30 I found, that logical database ADA using view V_ANLAZ (ANLA + ANLZ tables) for selecting data from DB. So I have created append for this view with my added fields to ANLA. Then I added the same append to structure ANLAV of logical database ADA.
My added field are now selected in AM reporting!
Can this solution break some SAP functionality?
Many thanks for answer!

So probably NOT...

ABAP Logical Database ADA

Hi All, I am quite familiar with Logical Databases but I need to understand the following.
1) I am using LDB ADA, but I want to use my own Selection Screen and not the default one that the LDB provides. I know I must put something in AT SELECTION-SCREEN but am unsure what.
2) Once I get the data, I want to store the data in an internal table - how do I go about doing this? If you can provide a code example that would be great.
Points for any relevant help.

Hi,
A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
Database access programming: Once youve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
Heres a step-by-step guide:
1) Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2) Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3) Youll be prompted for a short text description of your new logical database. Enter one. Youll then be prompted to specify a development class.
4) Specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you dont have to write a single line of code.
Noted point is we cant add any selection criteria thru our se38 program if you are attaching any LDB to program.Ist of no use.
If you want to change selection criteria to the existing LDB, you have to goto SE36 tcode and provide LDB name and choose "Change" mode by selecting "Selections" Radio button.
declaration of params is different compared to normal se38 program in some aspects.
PARAMETERS :p_curr LIKE bkpf-waers FOR TABLE bkpf OBLIGATORY.
this BKPF table should be one of the node in the "Structure" Radio button.

How to read data from Logical Database ADA for more than one financia year

Hi,
I need to read data from ADA logical database and ANLCV node for current financial year 2007 and for the next 3 years 2008, 2009, 2010. When I do this using program attached below, I receive only data for one year, which is entered at the selection screen in the field BERDATUM. How should I modify my program to read ANLCV node for more then one year ? Could anybody help me ?
Kind regards,

Selection screen and logical database PNP

hi all,
I am having a requirement to produce a HR Report where i need to use logical database PNP. Now the issue is i need to supress some of the elements of standard selection screen of PNP and add a couple of fields of mine.
i have been looking all around and i got few of the below methods.
its good to use a report category.
somewhere it says include it in ur program using selection screen block..
can you please guide me which is the best way and what would be a perfect solution?
thanks in advance,
Reena

In the Program Attributes, click on the pushbutton 'HR Report Category'.Click on the 'Create' icon in the pop-up window that comes up. You will get a list of all the available Report Categories. Go through the list & if you don't find one that suits you, select one that is closest & click on the 'Copy As' icon in the menu bar..
Now, you can remove the unwanted fields & add yours for selection. save it & and attach it to report in the attributes.

Field symbols and logical databases

Hi,
How to use field symbols in an abap HR program with logical database? For most of the reports and interfaces in HR, I have used GET PERNR with logical database to fetch data from the tables. I understand that this method of programming using logical databses, is less coding and improves the performance. I am curious to know the usage of field pointers here. How does this help? Is it necessary from a performance point of view? I would like to look at an example that has LDB and field symbols used in combination. I did not find one in the threads.
Any thoughts and what do you recommend?
Thanks in advance,
VG

Field-Symbols utilize memory more efficiently.Hence Better utilization of memory better is performance.
Memory utilization is one of the factor for performance.

Transaction ME80FN, SAP Query ME80FN, and logical database MEPOLDB

I am looking at transaction ME80FN. Is that from the global query /SAPQUERY/ME, ME80FN? I was told that ME80FN was from SAP Query... but doubts are creeping in.
   SE93 shows trans. ME80FN as Program RM06EAAW and no logical database. RM06EAAW has different headings and an additional toolbar in the results screen.
Did RM06EAAW get generated from SQ01 ME80FN?
   I have to modify the ME80FN transaction output by adding a field to the PO History display, which is selected from the bottom toolbar, rightmost button. I guess I have to go with RM06EAAW as the starting point(?).
   We are on 4.6B Any suggestions are welcome.
Thanks

These are what I am dealing with:
Transaction ME80FN
/SAPQUERY/ME, ME80FN query.
Another way to word the question is: How can I make a copy of the global query /SAPQUERY/ME, ME80FN to have that nifty bottom toolbar that transaction ME80FN has?
At first glance, they are the same entity... But the toolbar in the transaction and display options via the last button on the toolbar differentiate the two.
   Thanks....

Regarding Query and Logical database

Hi All,
I have one requirement to create a report which gives all selection fields of a query.I got the selection fields defined in the query,but some extra selection fields are coming from logical database,which query uses.These extra fields count is different for different queries using same logical data base.Please suggest me a solution.

Shibin

Hi Jogeswara,
Thanks for your inputs.
But my question is, how can I filter the data which is being fetched by standard logical database. I cannot go inside the std. LDB and change internal tables of it. I tried coding in extras, but I think it works only if we want to add additional fields in output.
At present, we are considering the option of creating a z LDB where we copy. std. LDB and also add the reqd. table which is not present in LDB.
Is there any other option?
Please provide your valuable inputs.
Regards,
Imran Kundan.

Logical Database ADA

Hi,
I am using logical databse in a program but it is not giving all the assets compared to the standard report 'AR02'.
Kindly advise.
Rgds,

Standard programs may use combination of different tables or logical database.
So you cannot expect both of them to be same.check the program of AR02 for more details.
