Add a Selection Screen to a Table Maintenance Dialog
When end users will maintain a z-table with 100+ rows, it helps to be able to restrict the selection by any number of selection criteria. This document attempts to define a “best practice” method for calling a table maintenance dialog from a selection screen.
Current Table Maintenance
The standard way to show a table maintenance dialog is via SM30, Call View Maintenance –
– or a custom parameter transaction that calls SM30 for a specific table, with parameters VIEWNAME and UPDATE = ‘X’.
Neither of these provide an initial selection screen. Entries can be restricted by checking the “Enter conditions” radiobutton, but users are more familiar with selection screens than with the dialog box that pops up. Therefore it is good UI to use a selection screen instead of the “Enter conditions” radiobutton.
Example Selection Screen Definition
In this example, an executable report has been created with selection screen.
DATA mytable TYPE z_mytable.
DATA selections TYPE TABLE OF vimsellist.
DATA selection TYPE vimsellist.
SELECT-OPTIONS: so_selop1 FOR mytable–myfield1,
so_selop2 FOR mytable–myfield2.
PARAMETERS: p_param1 TYPE z_mytable–myfield3,
p_param2 TYPE z_mytable–myfield4.
Calling Function Modules
When the user clicks execute, the program needs to read their selections and call the table maintenance dialog. The following code shows how this is easily done by using function modules ‘VIEW_RANGETAB_TO_SELLIST’ and ‘VIEW_MAINTENANCE_CALL’.
CALL FUNCTION ‘VIEW_RANGETAB_TO_SELLIST’
fieldname = &1
append_conjunction = ‘AND’
sellist = selections
rangetab = &2.
IF &2 IS NOT INITIAL.
selection–viewfield = &1.
selection–value = &2.
selection–and_or = ‘AND’.
selection–operator = ‘EQ’.
APPEND selection TO selections.
add_sel ‘MYFIELD1’ so_selop1.
add_sel ‘MYFIELD2’ so_selop2.
add_par ‘MYFIELD3′ p_param1.
add_par ‘MYFIELD4′ p_param2.
CALL FUNCTION ‘VIEW_MAINTENANCE_CALL’
action = ‘U’ “for Update
view_name = ‘Z_MYTABLE’
complex_selconds_used = ‘X’
dba_sellist = selections
OTHERS = 1.
IF sy–subrc = 1.
MESSAGE ID sy–msgid TYPE sy–msgty NUMBER sy–msgno
WITH sy–msgv1 sy–msgv2 sy–msgv3 sy–msgv4.
Horray! That is all. In only 46 lines (plus two for every select-option or parameter), this will bring the user to from the selection-screen to the table maintenance screen.
This is a collaborative document. If there are better ways of achieving this functionality don’t hesitate to chime in and contribute!
Nice one. A very good way to add selection screen.

Thanks for sharing . useful Information.
Excellent article, thank you!
Just a Function module to do the job ....
Nice one to know .
Great work! But not perfect.
Let's say you have a table with a field type QUAN 13,3.
Now you do your selection in the dynamic selection screen for this field from 1 to 5.
ABAP will dump, saying "ASSIGN_OFFSET_NOTALLOWED".
"Part of the source field "<VALUE>" was assigned to a field symbol,
but this is not allowed for fields of type "P"."
Any one has a solution for this?
I'm dealing with the same problem. For me it seems to be a bug in form TRANSLATE_SELLIST_TO_WHERETAB of program SAPLSVIX.
I tried many things but have no solution yet how to fill DBA_SELLIST.
I'm still working...
Correct, the mistake is in TRANSLATE_SELLIST_TO_WHERETAB.
I already made a call at SAP, first they told me VIEW_MAINTENANCE_CALL is not released, I told them it is (see help "The function moduel has been released"), nothing more since last contact yesterday.
If there are any updates I will let you know...
Did you try this method - Using selection-screen in Table Maintenance Generator - ABAP Development - SCN Wiki?
i am also getting same error.Please tell me how you solve this.Please do needful.
Thanks & Regards,
you need to implement note 2007905
Then I have added some coding (function RS_DS_CONV_IN_2_EX) "in between" to convert my selection values to internal format (decimal point, ...)
Hope this helps
Thank You for reply.and how to edit the values of selection screen like key fields.for example i enter the value in selection screen in output if i am trying to edit the values getting following error.
Specify the key within the work area
Sorry for seeing this too late 🙁
I had a different take on this problem & had documented it as a WiKi - Using selection-screen in Table Maintenance Generator - ABAP Development - SCN Wiki.
I use function FREE_SELECTIONS_DIALOG to create dynamic selections for a pool of different tables of our application.
Then I convert export parameter EX_FIELD_RANGES to DBA_SELLIST to call VIEW_MAINTENACE_CALL.
For the conversion I use VIEW_RANGETAB_TO_SELLIST and some code of my own, depending on field type.
But that doesn't work for fields of type P.
I don't use the VIEW_MAINTENANCE_CALL function. I use the TMG event AA and call the selection-screen in there.
Interesting, i thought that the FM is "released". But if you see the date it is blank 😯
Something fishy is going on there 😛
For it means "has always been released" or "released in time so old that no one in Walldorf remembers" .
You can also check in documentation at help.sap.com that SAP suggest their usage (From Middle level entry - BC Extended Applications Function Library - SAP Library for ERP 6.0 to Middle level entry for good old 4.0)
Just to clarify, when i said -
i meant for this scenario. I have used this FM many times & it has always worked like a charm 🙂
Thanks for the feedback everyone! I'm learning a ton.
I like how Suhas' method uses the standard events instead of slapping an executable report on the front end. Perhaps we can combine our document and wiki and determine a best practice.
My only concern with his method is the filtering on the application server and not the database - is that the right choice in this scenario? And does VIEW_MAINTENANCE_CALL do the same thing?
Thank you very much!
