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,
L

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

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,

We can -

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....

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...

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.

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.

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.

Changing logical database DDF select order, and restricting the selection

HI all,
I am using logical database DDF for a report. I would like to do two things:
1) Change the sort order of records so that when my GET statements are processing, they are bringing the data back in sorted by a field of my choice (such as KNA1-REGIO, or KNB1-BUSAB).
2) I would like to add KNA1-REGIO and KNB1-BUSAB as fields for selection during the LDB's initial selection, instead of filtering out records during the GET statements.
FYI, I did find the field DD_BUSAB in the LDB selection structure which I can use to restrict KNB1-BUSAB. I am still not sure how to restrict by KNA1-REGIO though.
Any thoughts?
Thanks so much,
L

Changing logical database

Hiii
There is a program MM60 which is really causing a issue of performance.
A copy of mm60 was done with additional column added . the issue we are actually having is that the program is taking too much time.
After analysis we have found out that there is GET XXX statement which are not necessary and which is being done by the copy program.
Can we just comment it or change the copy logical database to optimize the code . i would like to know the impact?

If you have made a copy , the try to do performance tuning of object.
Check which select statement/ABAP logic is taking more time.
You can also try to avoid this Logical database by using database tables directly.
Check ST05 ans SE30 output.

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.

KTANSW in ANLAV table (structure)
ANLCV derives its partly from table ANLC and the remaining is derived on the basis of some computation.
how does it calculate

Changes to View in logical database(SE36) is not saved in transport.!!

Hi ,
Logical Database: ADA
Selection view: CUS
We did few changes to the view for table fields ANLAV in SE36 .
When I press save, it is not asking for transport number.
How i can save these entries in transport? Do I need to manually place in the transport?
Kindly Suggest.
Thanks

How to retrieve data using logical database and custom select options

Hi all,
I have a selection screen which is displayed by logical database PSJ and I have two select options of my own. I need to retrieve data based on both selection screen of logical database and my own select options. How can I do it?
Thanks in advance.

Hai Gupta
Check the following Document & Links
1. A logical database is in fact
a program only.
2. This LDB provides two main things :
a) a pre-defined selection screen
which handles all user inputs and validations
b) pre defined set of data
based upon the user selection.
3. So we dont have to worry about from
which tables to fetch data.
4. Moreover, this LDB Program,
handles all user-authorisations
and is efficient in all respects.
5. tcode is SLDB
good info about Logical Database. you can check the link.

Re: Logical databases
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9bed35c111d1829f0000e829fbfe/frameset.htm
Functions for displaying and changing logical databases:
Call Transaction SE36 or
Choose ABAP Workbench -> Development -> Programming environ. -> Logical databases
Interaction between database program and report:
During program processing, subroutines are performed in the database program and events are executed in the report.
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
advantages:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.
disadvantages:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event
statement (such as another GET or an END-OF-SELECTION).
1. transaction code SLDB.
2.enter name z<ldb-name>
3.create
4.short text
5.create
6. name of root node (here Ekko)
7. enter short text (f6)
8.node type -> data base table.
9.create
10 change logical DB
riht click on ekko and insert node
here node name ekpo
11.create
12. click on selections
13. press no Should the changed structure of Z<ldb name> be saved first.
14.select tables which you want to join.
15.transfer
16 now you have to o to coding part.
17. save
activate.
19.click to src code
double click on first include and activate

How to select a new table in logical database after creating the Infoset

I have created a abap query report ,i have used logical data base ADA in the infoset in SQ02.In the logical database i had selected only two tables then ANALV and ANLB.Now my client wants one more field to be added and thats is from table ANEK.Now i need to select this table in logical database ADA.
Please assist on how to select another table available in the Logicaldata base now which i didnt select when i created the query

Markus,
I have now selected the additional field Posting date in Document ANEK -BUDAT .Earlier the report had the fields from ANLCV - Current acquisition value ,ordinary dep posted selected for the output.
When i run the query after adding this new field ANEK-BUDAT the below warning is generated by system :
The query specifications cannot be used to generate a list,
i.e. the query will probably not return the list you desire.
If you still want to execute the query, please use the
"Generate" function
-> 'Generate'
Fields from parallel tables within a line*
Line: 01
Field: Posting Date in the Document
(ANEK-BUDAT, table ANEK)
Field: Ordinary depreciation posted
(ANLCV-NAFA GEB, table ANLCV)
Fields from parallel tables within a line*
Line: 01
Field: Posting Date in the Document
(ANEK-BUDAT, table ANEK)
Field: Current asset acquisition value
(ANLCV-LFD KANSW, table ANLCV)
2 warnings for query QUERY ***
Please advice .How get this new field added.
