Maintenance view concept clarification needed

Hello all,
   lets take the following into consideration:
     1st DB table - element1(key) , element 2(key) , element 3.
     2nd DB table - element1(key)
     3rd DB table - elemtent2(key)
there is a foreign key relationship created for element1 and 2 of DB table1 to DB table2 and 3 respectively.
I have created a maintenace view for db table1 and want to allow users to create new entries throught transaction sm30.
However because of foregin key relationship the user will not be able to create any new enteries.
How do i solve this problem?
Thanks in advance.

Hi,
You'll first have to populate DB2 before inserting any records into DB1.

Maintenance view on the standard table

Hi,
We need to have a maintenance view on the standard XYZ table .
Since it is a std table. we would not be able to create a maintenance view since we need an access key.
So we have to :
1. Copy the table XYZ into a Z_table. (just the structure alone).
2. Create a table maintenance generator on this table.
3. When the data is being saved in the maintenance view, update the record in the XYZ.
How we can populate the XYZ when the Z_table is populated with data?
Can anyone help in this regard.
Thanks and regards,
Kapil

Hi Rich,
Thanks for your reply.
I am referring to standard table "comc_settyp_attr" in SAP-CRM system . I have copied it and created a z_table. But its not allowing me to create a maintainance view. Its giving an error :
GUID in table key (Field name CUSTINFO) not supported.
But when i create the z_table without the GUID(char 32) as key field, it generates table maintenance. But the key field is required.
Can you help me in this regard.

How Can I Include a Transaction in Maintenance View

Hi All,
Can anybody help me on how can I release transactions to be available to the end user by putting it in maintenance view? There is a request to include the transaction S_ALR_87001487 into the maintenance view put I need to know how can I achieve this.
Thanks,

Hi Ahmad,
Can you please explain clearly.
Are you asking us on how to create a maintenance view for transaction S_ALR_87001487 . You can create a Z transaction of similar attributes as that of standard one and give authorizations for the ztransactions for which user will be allowed to edit.

Using user-defined transport recording routine with table maintenance view?

Hi,
I have a table that is maintained through a maintenance view. I need to record the changes to a dedicated transport object (not TABU) with my own recording routine instead of teh standard recording routine.Could someone tell me which/how the events can be used to achieve this?
Regards
Rachana

Hi Rajeev,
I have changed TMG to choose the option - User defined routine. And I have created a new transport object in SOBJ for the table. Is this enough to record the object to the transport as the object i defined instead of TABU? Do I need to write some subroutine for any view event to achieve this? Do you mean to use the menu option to include the object to a request?
I have a bigger problem where this view is actually part of a view cluster. Even in that case is teh above steps enough?
Regards
Rachana

Need to create maintenance view for a custom infotype

A custom infotype 90XX is created. The data cannot be modified or created through PA30 in this infotype. Through PA 40 actions only we can create/change the record/data. We have created some 1000 records in it. Now can we create a maintenance view for the infotype so that we can create, delete or change the data in the infotype as and when we want.

Hi,
pls chk dat u have maintained the 'Infotype Charecteristics' and 'Technical Attributes' correctly.
thanks,

What is maintenance View . Why do we need to go for maintenance View

Hi,
I wanted to create maintenance view. Before that i wanted to know what is maintenance veiw and why do we go for maintenance view

SE11, enter the table name click change. In the next screen, click Utitlies-->table maintenance generator.
Enter &NC& as the auth group.
Enter the function group to use (ex. Z_TABMAINT)
click One Step, enter '1' as the screen number. Click the create button.
Once generated, you can use it by going to SM30, enter table name and click maintain

Hiding a Maintenance View in a View Cluster

Hello ABAP Experts,
We have a scenario where we would like to hide a maintenance view to an existing view cluster based on condition.
Is it possible via events of a view cluster, where i can hide the view at runtime based on some condition before the view cluster is displayed ?
Is there any way as well, which help achieve this hiding of views ?
For example in the below View Cluster, i would like to hide "Define object links" view from the main view cluster "Define document Types".
Thanks,
Naresh

Hi Naresh,
Yes, you can do it in events of a view cluster, define a subroutine and bounding it to event(02) in SE54,
when you define the subroutine, it will ask you creat a mian program, in this main program, you need 'INCLUDE lsvcmcod'.
Then you can access some standard data, http://help.sap.com/saphelp_nw04/helpdata/en/62/c302c7de8e11d1a5960000e82deaaa/frameset.htm
INCLUDE lsvcmcod.
FORM yourSubroutineName.
DATA: viewname TYPE vclstruc-object,
        error_flag TYPE vcl_flag_type,
viewname = 'ZTEST_VIEW1'.
* PERFORM vcl_set_table_access_for_obj USING    viewname
*                                       CHANGING error_flag.
----> according your condition to change the view.
IF xxx = yyy.
DELETE vcl_struc_tab WHERE object = viewname.
ENDIF.
ENDFORM.

Archer

Can I use classes and methods for a maintenance view events?

Hello experts,
Instead of perform/form, can I instead use classes and methods, etc for a given maintenance view event, lets say for example I want to use event '01' which is before saving records in the database. Help would be greatly appreciated. Thanks a lot guys!

Hi viraylab,
1. The architecture provided by maintenance view
   for using EVENTS and our own code inside it -
   It is provided using FORM/PERFORM
   concept only.
2. At this stage,we cannot use classes.
3. However, inside the FORM routine,
   we can write what ever we want.
   We can aswell use any abap code, including
   classes and methods.
(But this classes and methods won't have any
   effect on the EVENT provided by maintenance view)

How to create a variant to a maintenance view (trans: SM31)

Hi gurus.
I have created a maintenance view (called z_jest). By running it from SM31 there is a variant option. However, I am not able to create the variant which I want to filter a selection upon in this transaction.
I have even looked into transaction SE54 and created a variant for the maintenance table view there( called z_jestv). Then going back to transaction SM31 and view z_jest, i push 'Variant' radiobutton and type as variant: 'z_jestv', I only get the message: "Variant z_jestv for object z_jest does not exist".
Can anybody please advice on how to create and/or connect the variant to the maintenance view?
Regards LL.

Hi Mahalakshmi
Thanks for reply.
When I look into the procedure, there is a prerequisite: "The basis dialog for which the maintenance variant is created already exists."
I am a little bit unsertain if I miss this 'Basic dialog'. Can you please advice on how to check / create this 'basic dialog' before I go on to create the variant. (I need this 'basic dialog' as input in the procedure you sent.)
(Note: I have already created a 'maintenance dialog' for the view, but I have a feeling, that is something different...)

Using DYNP_VALUES_UPDATE with a Maintenance View

Hi,
I am using a maintenance view to insert values into a table. When user creates a new entry, based on the value provided for a field,I need to fill a read-only field. In PAI, when user enters a value for one field, I am using FM 'DYNP_GET_STEPL' to get the current line and then DYNP_VALUES_UPDATE to fill the contents to the read-only field. But this does not seem to work. Any idea?
Regards
Rachana

Hi Tamas,
I tried both the options suggested by you.
I am updating the underlying structure, still its not visible when the screen loads again. But if you see the same field gets filled with DYNP_VALUES_UPDATE if an F4 help is used for teh first(editable) field and then my read-only field is also filled in the PROCESS ON VALUE REQUEST module.
So my guess is that, since it is a table control, it loops through the rest of the table control which is empty and my underlying structure gets cleared. So the problem could be where I am actually filling the field.
Is it possible to somehow fill the <EXTRACT> table so that teh value is not lost?
Regards
Rachana

Unable to edit maintenance view in SM30

hi everyone.
need your help, I have one custom table, let's call it YTAB. This table has several maintenance views created for it, depending on company code. For YTAB, i have created a maintenance view YTABX.
When we moved YTABX to PRD, we cannot edit it in SM30. The user ID has the right authorization. The error message is "client 100 not modifiable". When I try to edit the mother table YTAB in PRD, I am able to go in and do the changes.
I have already compared the settings for YTABX with the other existing views, they are the same. My settings for the view are:
Access: Read, change, delete & insert
Delivery Class: C
In the table maintenance generator, i have a 2-step maintenance type, recording routine is Standard recording routine and compare flag is automatically adjustable.
Attributes for table YTAB also has delivery class C, table category is transparent table, table maintenance is allowed.
Thank you in advance.

Hello roch,
the direction in which mark points is right but i think you should get some more information on the principles of table types and sap system landscape.
Usually you should not be able to directly maintain any table. This is not only bad style but also a huge risk for the system consistency. That's why application data is always maintained via some kind of application which ensures that the data is vilidated before it is stored.
Customizing data should only be maintained within a development system and then transported through the landscape. To maintain these table you can use generated views, customer developed maintenance views, view clusters which all include automatical link to the transport system. If you would maintain these tables directly in the productiion system it would have another configuration than the development and the quality/test system which makes them more or less useless as you can no longer make any serious test if the server configurations differ.
To prohibit changes of customizing tables on production and test servers the admins lock the systems which results in the message you got. This setting is made in TCODE SCC4. Even if you have for any reason the authorization to use this transaction you should in no case change these settings without approval of basis / system owner.
Kind Regards
Roman

Updates through a maintenance view

Hi,
I'm having difficulty with maintenance views. I thought it ws possible to construct a maintenance view consisting of two or more tables and be able to update non-key fields in any table, provided the tables were linked via FK and had suitable cardinality of C:1.
However, this seems to be what I've found: you can only update non-key fields in the primary table. Although fields in the secondary tables appear as though you can update them (via SM30), any data changes you make are erased (as you look at it!) when you hit Save - the original value returns.
Is my assessment correct? SAP Help is vague and ambiguous on the matter.
Also, maybe someone could explain the cardinality requirements. SAP Help states the FKs must have N:1 cardinality, but as far as I can see it should be C:1.
Thanks,
T.

Hello Tenchy
You are talking about view clusters (SE54) where you have hierarchical linked tables that can be maintained together.
Obviously, you cannot edit key fields of the primary table. Instead you need to use execute two operations:
- DELETE entry
- CREATE new entry
It goes without saying that the same operations are propagated to the dependent entries in secondary tables.
The cardinality between primary table and secondary table should be 1:N meaning
- for each entry in the primary table you can have none or multiple entries in the secondary table
- you cannot have secondary records for which the corresponding primary record does not exist

How to read data in a program from a MAINTENANCE View

Hi Experts,
Requirement:
1. I have maintained a maintenance view on three Database tables.
2.Data can be entered in the view as it is a Maintenace view as i have created maintenance generator for that and it is a requirement.
3. In one of my programs i need to read this data, into an internal table, that is maintained through this view.
Problem: When i am firing a SELECT query on this view, it goves me a syntax error that i cannot get data by select query on a Maintenance view.
Solution required for: Is there any way i can get the data from this Maintenance view.
Thanks in advance for your exteemed replies.

Raghavendra Goutham P.

Hi,
   Only projection view or database view can be used
   in select query.
    Find the tables used in view and

Disable delete button in a maintenance view

Hi,
Does anyone knows how can I disable the delete button in a maintenance view so when a user that is not authorized can´t delete any row, or how can I lock the delete subroutine.
Thanks!

Hello Moises
The problem with this solution is that if you ever need to modify your maintenance view (i.e. regenerate the dynpros because you may want to add new fields) your coding is gone.
This is not the case if you are using event 19. Below you see same sample coding:
***INCLUDE LZUS_SDN_MAINTF01 . " Function Group with maintenance views
* Event 19: After Init. Global Variables, Field Symbols, etc.
* http://help.sap.com/saphelp_nw2004s/helpdata/en/91/ca9f44a9d111d1a5690000e82deaaa/content.htm
FORM exclude_gui_function.
* define local data
DATA: ls_excl   TYPE vimexclfun.
ls_excl-function = 'DELE'. " taken from standard GUI-status 'ZULG'
BREAK-POINT.
AUTHORITY-CHECK OBJECT 'F_BKPF_BUK'
           ID 'BUKRS' FIELD '1000'
           ID 'ACTVT' FIELD '02'.
IF ( syst-subrc NE 0 ).
    APPEND ls_excl TO excl_cua_funct.
ENDIF.
APPEND ls_excl TO excl_cua_funct. " Just for the purpose of demonstration
ENDFORM.                    "exclude_gui_function

That is the most important part. Thank you. But you seem to be unaware of the "search" functionality.
If you can imagine that you are not the first person to ask a certain question, then you can be sure that someone else already has and you can find the answers on your own. If you still have doubts, then ask a specific question providing the details.
Based on your other questions, you are on release 4.0B. Is that still correct?
Cheers and thanks for responding,
