problem with NEXT and PREVIOUS buttons!

[Former Member]

Hiii Everyone,

i'm brand-new beginner to programming in ABAP, and i'm facing a problem with my program and i wish for u to help me.

If there is more than 1 record under the same customer number, the user will be able to navigate through records using the previous and next buttons or to do that from the title bar buttons. The thing is, I don't know the code of how to make it go backward and forward through the records.

please need ur help in this and thank u in advance.

Check the Following Sample code

For Next

Program - LKKBLF01

Form - form scroll_end tables rt_columns type kkblo_t_columns.

For Previous (same Program)

form scroll_left tables rt_columns type kkblo_t_columns.

Hi Sir,

bcoz of it's under MODULE USER_COMMAND_7100 INPUT, so an error message appears to me said, " INCORRECT NESTING: BEFORE THE STATMENT "FORM" THE STRUCTURE INTRODUCED BY "CASE" MUST BE CONCLUDED BY "ENDCASE" which is already there!!!

ENDMODULE. " USER_COMMAND_7100 INPUT

[Kanagaraja_L]

form scroll_end tables rt_columns type kkblo_t_columns.

form scroll_left tables rt_columns type kkblo_t_columns.

Remove the above Form statements.Errors will be solved.

given Example for your reference you cant use directly so check the logic inside the form and make it for your requirement

[Former Member]

this FORM should be defined somewhere right???

like when use FORM and PERFORM.

bcoz the error still there

[Kanagaraja_L]

WHEN 'NEXT'.
form scroll_end tables rt_columns type kkblo_t_columns.


Endform.

WHEN 'PREVIOUS'.
form scroll_left tables rt_columns type kkblo_t_columns.

endform.

I want to Know where you are calling those forms like perform scroll_end . and Perform scroll_left ?

You have to Declare TYPE_POOLS KKBLO.

and see the logic inside the Form (Standard form in include LKKBLF01)

[Former Member]

what kind of declaration???

......... TYPE_POOLS KKBLO???

[Former Member]

TYPE_POOLS are basically a grouping of types .i.e. when you have a type you want to use you can use a type without having to define it all over again!

[Former Member]

Yes thats my question... what is the kkblo_t_columns... is it table or what... how to declare it???

[Kanagaraja_L]

Yes Internal table You have to declare like below

TYPE-POOLS kkblo.

Inside your Program after that double click on KKBLO then you will navigate to Type-group and you can see the table definitions.

this is really getting me frustrated....really sorry gentelmen but now i got new weird error...

different number of parameter in FORM and PERFORM ( routine: SCROLL_END, number of formal parameters: 1, number of actual parameters: 0 ).

[Former Member]

Hi,

You seem to be getting a helluva compilation errors and you possibly cant list them out here for a chance that it might frustrate people who reply and also you

My suggestion:(considering the fact that you are new to ABAP) You can do a F1 on keywords which opens up a documentation for the keyword. You can also search the SDN for solution.

The error that you are getting is pretty straight forward. The number of formal parameters dont match with the actual parameters.

It essentially means that there is a difference in the number of parameters that you have used while calling the subroutine (PERFORM) and the definition of the subroutine (FORM...ENDFORM)

Use this

WHEN 'NEXT'.
  PERFORM scroll_end tables itab.

[Former Member]

I think the whole idea of having these errors is that the PERFORM thing is placed in "Module USER_COMMAND_7000 INPUT"... i don't know u r the expret coz everytime i got new error and still not working.

[Former Member]

Hello Gentelmen,

can i use the system function " sy_step1" sscrfields-functext_02 from table "sscrfields" and use the icons as function code???

the previous FORM and PERFORM thing didn't work so i'm changing the hole idea of it

please need ur help.
