Hi,
I'm not sure what you're asking in either question. It would help if you gave a specific example of what you want to do.

Views don't contain any data; they just query base tables.
You can change the definition of a view (CREATE OR REPLACE VIEW ...) so that it appears that the base table(s) have changed; that won't change the base tables.

Debugging a smartform without modifying the code ?

Hi all, please forgive my noobyness but it's the first time I'm working on smartforms...
Basically; I have a smartform that prints out a pdf showing all the entries of a purchase order, but there's a thing that I have to correct... The price amount for position is not correct, because it doesn't contains an extra amount, let's call this quantity "limit", that is a specific property of each row in the order.
Problem: I'm not that good to find in the code the exact point in which the price for a row is calculated, or better.... I thought I found it, did a little correction but without success.
I'd like to debug exactly the pieces of code that are in the smartform, how to do it without modifying the code ? I've read something about hardcoding a break-point but I won't insert new code because I'm working on a pre-production machine and porting a CR is not as easy. Is there any way to debug without doing a mod on the code? Thanks in advance.

Hi Matteo,
it's quite simple.
Found the Fm name of the SMARTFORM (Menu Utilities-> F.M. Name) (Something like
/1BCDWB/SF00000015).
Then go in SE37 transaction and put the FM founded and then display it.
Go in the main info of the FM (tab. Propierties) and the double click on the main program.
Then double click on the include that ends with *F01. There you will find all the code of your SF. Then you can put a breakpoint the piece of code that you want.
This should be works.
Let us know
Bye

How to update specific fields of a db table using MODIFY

Hi all.
I understand that MODIFY allows us to insert a record into the database if the a record with the same key is not there. If a record is there, it would update that record.
However, when the record is there, could i update SPECIFIC fields of the record, instead of updating ALL fields of the record?

Yes, you can with exception that you can not modify primary key values.
Here are the details about MODIFY db table command with examples
MODIFY - Change a database table
Variants:
MODIFY dbtab. or MODIFY *dbtab. or
MODIFY (dbtabname) ... .
MODIFY dbtab FROM TABLE itab. or MODIFY (dbtabname) FROM TABLE itab.
MODIFY dbtab VERSION vers. or MODIFY *dbtab VERSION vers.
Effect
Inserts new lines or updates existing lines in a database table (s. relational database). If a line with the specified primary key already exists, an UPDATE is executed. Otherwise, an INSERT is performed. You can specify the name of the database table either in the program itself in the form MODIFY dbtab ... or at runtime as the contents of the field dbtabname in the form MODIFY (dbtabname) ... . In both cases, the database table must be defined in the ABAP Dictionary. If the program contains the name of the database table, it must also have a corresponding TABLES statement. Normally, records are inserted or updated only in the current client. Data can only be inserted or updated using a view, if the view refers to a single table and was created in the ABAP Dictionary with the maintenance status "No restriction".
MODIFY belongs to the Open SQL command set.
When the statement has been executed, the system field SY-DBCNT contains the number of edited lines.
The Return code is set as follows:
SY-SUBRC = 0:
 All lines were successfully inserted or updated.
SY-SUBRC = 4:
 One or more lines could not be inserted or updated.
Notes
 1. You cannot modify a line if there is already a line in the table with identical key field values in a UNIQUE index.
 2. Automatic definition of INSERT and UPDATE is expensive. You should therefore use MODIFY only if you cannot define the INSERT and UPDATE cases yourself in the program.
 3. Since the MODIFY statement does not perform authority checks, you have to program them yourself.
 4. Adding or changing lines with the MODIFY command is only completed after a database commit (see LUW) has been performed. Before the database commit has been performed, any database changes can be reversed with a database rollback (see Programming transactions).
 5. Synchronization of simultanous accesses by several users to the same set of data cannot be exclusively achieved with the lock mechanism of the database system. In several cases, you are recommended to use the SAP lock mechanism.
Variant 1
MODIFY dbtab. or
MODIFY *dbtab. or
MODIFY (dbtabname) ... .
Extras:
... FROM wa
... CLIENT SPECIFIED
See Cannot Use Short Forms and
Cannot Use *Work Areas.
Effect
Inserts a new line or updates an existing line in a database table. If you specify the name of the database table yourself, the primary key for identifying the line to be inserted or updated and the relevant values are taken from the table work area dbtab or *dbtab (see TABLES). If you declare the name of the database table explicitly, the program must also contain a corresponding TABLES statement. If the name of the database table is not determined until runtime, you need to use the addition ... FROM wa.
Example
Insert or change data of the customer Robinson in the current client:
TABLES SCUSTOM.
SCUSTOM-ID = '12400177'.
SCUSTOM-NAME = 'Robinson'.
SCUSTOM-POSTCODE = '69542'.
SCUSTOM-CITY = 'Heidelberg'.
SCUSTOM-CUSTTYPE = 'P'.
SCUSTOM-DISCOUNT = '003'.
SCUSTOM-TELEPHONE = '06201/44889'.
MODIFY SCUSTOM.
Addition 1
... FROM wa
Effect
The values for the line to be inserted or updated are not taken from the table work area dbtab, but from the explicitly specified work area wa. When doing this, the data is read from left to right according to the structure of the table work area dbtab (see TABLES). Since the structure of wa is not taken into account, the work area wa must be at least as wide (see DATA) as the table work area dbtab and the alignment of the work area wa must correspond to the alignment of the table work area. Otherwise, a runtime error occurs.
Note
If a work area is not explicitly specified, the values for the line to be inserted or updated are also taken from the table work area dbtab if the statement is in a FORM or FUNCTION where the table work area is stored in a formal parameter or local variable of the same name.
Addition 2
... CLIENT SPECIFIED
Effect
Switches off automatic client handling. This allows you to edit data across all clients even when dealing with client-specific tables. The client field is treated like a normal table field that can be programmed to accept values in the table work area dbtab or *dbtab where the line to be edited occurs.
The addition CLIENT SPECIFIED must be specified immediately after the name of the database table.
Variant 2
MODIFY dbtab FROM TABLE itab.or
MODIFY (dbtabname) FROM TABLE itab.
Addition:
... CLIENT SPECIFIED
Effect
Mass modify: Inserts new lines or updates existing lines of a database table. The primary keys for identifying the lines to be inserted or updated and the relevant values are taken from the internal table itab. The lines of the internal table itab must satisfy the same conditions as the work area wa in addition 1 to variant 1.
Note
If the internal table itab is empty, SY-SUBRC and SY-DBCNT are set to 0.
Addition
... CLIENT SPECIFIED
Effect
As for variant 1.
Variant 3
MODIFY dbtab VERSION vers. or
MODIFY *dbtab VERSION vers.
See Cannot Use the VERSION Addition.
Note
This variant is obsolete.
Effect
Inserts a new line or updates an existing line in a database table, the name of which is taken from the field vers at runtime. If no line exists with the specified primary key, an INSERT is executed. Otherwise, an UPDATE is performed. The database table must be defined in the ABAP/4 Dictionary and its name must conform to the naming conventions for R/2 ATAB tables. These stipulate that the name must begin with 'T' and may contain up to four further characters. The field vers must contain the table name without the leading 'T'. Only lines in the current client are inserted or updated. The line to be inserted is taken from the statically specified table work area dbtab or *dbtab.
SY-SUBRC is set to 0 if the line is successfully inserted or updated. SY-SUBRC <> 0 is not possible since any other result causes a runtime error.
Hope this helps.

How to update software without wi-fi? It shows message that first connect to wi-fi then update even if I have 3G net on my phone i5.

Hi Parmkshinde,
Here's why you should use Wifi to do a wireless software update:
While you'd be able to download an update over 3G/4G, the updates are so big that you'll be waiting a really long time (also, you'll eat up a ton of your monthly wireless data), so Wi-Fi is much easier here. You should also make sure you've got plenty of battery life. The download and installation process can take some time, so if you've got less then 50% battery, you may want to plug in to a power source.
Hope this answers your question!
Cheers,
GB

How create mail alert without triggering the event.

1. SR 3-4924626351: How create mail alert without triggering the event.
We wanted to send alert mail every 10 days or 15 days or 1 month to a reporting manager of Opportunity Owner with details of that Opportunity. I don’t want to use any triggering of event like the Following. When new opportunity is created When modified Opportunity is saved etc.

Raju,
If you don't want to use the triggering event, you will have to do this manually.
Manually:
- Create a Web Link on the SR with and embed the mailto: function with the receivers email and subject and body embedded in the url (you can find this link on Google)
- When this link is clicked, an email window will open with all the details you provide, and you can click the send button to send the email.
- You will have to do this manually every 10-15 days or whatever is the duration
Auto:
- Create a time based workflow on a new Opportunity Created event
- create a action to send an email notification to the concerned person (details in the workflow properties)
- This workflow will auto send an email every 10-15 days to the opportunity Manager.
The time based workflow is the best option I see. Do you see any issue/ concerns with auto generated emails?
Hope this helps!

Duplicates of a song on iPhone 4s but not in iTunes. Unable to delete duplicate. Won't play and won't let you swipe to delete. Any ideas on how to do so without resetting the phone?

I have duplicates of a song on an album. One of the duplicates is grey with no album cover. When you attempt to swite and delete, the track will not delete and will not even play. I've contacted iTunes store and the person I received the support email from told me that it may not be downloaded. I emailed him back and explained that no there is no download for that song in my itunes store on my phone.
One I never received an answer back which shows you how well these people do their job.
Two: I really would prefer to have a solution to this problem without having to delete all of my music from my phone or resetting my phone. Because this duplicate isn't even showing up in my iTunes, it's only showing up on my phone.
When I attempt to find it in my itunes it plays fine. But when I try to find the file to delete it, it is no where to be found. I've tried everything that I could think of to get rid of it. And I don't want to leave the album/artist off my phone because I do enjoy their music... And I have the microsoft sync in my car.
Anyone got any ideas on how to do this without resetting the phone and/or taking my music off?

If you have all your music on the cmputer then i would connect up my phone uncheck the Sync Music option and apply.
This should take all the music off your phone .Then you can resync the music back on to it.
If this doesn't work maybe a restore to factory settings and start from scratch is the way to go
