dynamic screen

Former Member — Mon, 25 Jul 2005 17:02:05 GMT

Hi,

I want to create a screen with SE51 and design the fields in layout at runtime.

For example I got a Z table (let's call it ztab) that contains fields (zfld1, zfld2). I want to create a screen with these 2 fields as Input field. But if in the future I add a 3rd field I want my screen to able to take in account dynamically.

it's possible?

thanks,

joseph

I have never seen that sort of thing done. I am not going to say that its not possible, but I have never seen this before.

check out this function module , i guess this may be the one you want

VIEW_MAINTENANCE_CALL

if not the source code would give you an idea.

Yes me too....

I was thinking: <b>if it was possible</b> so why every time that i add a field in table I have to refresh his view maintenance in se54?

I keep looking for an answer. If i find something i will let you know

using this screen what will you be doing? a report generation? maintenance utility? if so as i said before you could use

function module

RS_TABLE_LIST_CREATE

pass "ANZE" to action parameter and

the desired table name to the table_name parameter

use FM

VIEW_MAINTENANCE_CALL

with action parameter as 'U' for update

and view_name as the table name.

hi Raja,

I was just wondering how can I create a screen dynamically with se51.

When I look at the screen SAPLSSEL 1106 it's seems that it's possible.

athavanraja — Mon, 25 Jul 2005 17:40:10 GMT

i am also sure that it should be possible, otherwise how could se16, selection screen (1000),table maintenance generator, etc all gets created at runtime.

If you need to generate a selection dynamically, you could use the following functionality. These statements are reserved for SAP use only and is not recommended that you use them. SAP will probably not support any program using these.



report zrich_0001 .

data: programname type sy-repid,
      program type table of progtab with header line.
data: syindex(5) type c.
data: mess(72), lin(72), wrd(72).

programname = 'ZRICH_0010'.

program = 'report zrich_0010.'.    append program.

do 20 times.
  syindex = sy-index.
  shift syindex left deleting leading space.
  concatenate 'select-options: s_' syindex  into program.
  concatenate program 'for sy-datum.' into program separated by space.
  append program.

enddo.

syntax-check for program message mess line lin word wrd.

insert report programname from program.

submit (programname) via selection-screen  and return .

delete report programname.

Hi Joseph,

Here is the sample code for dynamic selection-screen.

START-OF-SELECTION.

PERFORM DYNAMIC_CODE.

FORM DYNAMIC_CODE.

APPEND 'REPORT ZSEARCH NO STANDARD PAGE HEADING.' TO ITAB.

CONDENSE REC_CNT NO-GAPS.

IF P1 = 'X'.

CONCATENATE 'PARAMETERS:F' REC_CNT

it is possible but not advisible to do like that according to sap

GENERATE - Generate a screen

Note

This statement is for internal use only.

Incompatible changes or further developments may occur at any time without warning or notice.

GENERATE DYNPRO h f e m ID g.

...MESSAGE F1 ...LINE F2 ...WORD F3.

Parts marked with " ..." are interchangeable

Extras:

1. ... OFFSET f4

2. ... TRACE-FILE f5

Effect

Generates the screen specified in the field g.

Here, the source code is taken from the structure h and the internal tables f, e and m. The field h (screen header) should correspond to the structure D020S, the internal table f (field list) to the structure D021S, the internal table e (flow logic) to the structure D022S and the internal table m (matchcode information) to the structure D023S.

If a syntax error occurs, the error message is stored in the field f1.

If a syntax error occurs, the number of the incorrect line is stored in the field f2.

By reading the return code value, you can determine whether this line refers to the flow logic or the field list.

If a syntax error occurs, the incorrect word is stored in the field f3.

The Return Code is set as follows:

SY-SUBRC = 0:

The screen was generated.

SY-SUBRC <> 0:

The screen could not be generated.

SY-SUBRC = 4:

The error is in the flow logic.

SY-SUBRC = 8:

The error is in the field list.

Addition 1

... OFFSET f4

Effect

If a syntax error occurs, the position of the incorrect word is output in this field.

Addition 2

... TRACE-FILE f5

Effect

Stores performance data in this file. This addition automatically switches on the trace mode.
