replacing editor-call

Former Member — Mon, 30 Jul 2007 15:51:23 GMT

hi , after recently upgrading from 4.6c to ecc6.0 we have experienced various program incompatibilities. I have the following problem can anyone help ?

I have a program that performs an editor-call for an internal table , however this no longer works.

I have been trying to utilise the cl_gui_textedit class as per saptextedit_demo_3 and am having problems displaying the contents of my internal table within the control window. again I have tried a number of set / get methods from the mentioned class without success. I receive the message that my internal table is not of type 'C'.

Any suggestions greatly appreciated.

Could you post a little bit of the code, specifically where you define the internal table, and where you invoke the GUI text editor control in a custom container...?

Hi thanks for your response, I have not included the specific program I wish to change as it is huge, but my initial representation to ascertain how this would work for me. I have litle 'OO' experience , so I expect glaringly obvious errors but am appreciative of any guidance.

I have posted all of the code, as it is only a small demo.

Sorry for slow response - had no system access. Looking at the code, I'd suggest the problem is probably the structure you are passing into the text control - rather than having it_mara like mara, maybe structure it with:

data:
  begin of gs_mara,
    matnr               like mara-matnr,
  end of gs_mara,
  gt_mara               like gs_mara occurs 10.

Hi many thanks for your response - all works fine until I add a typ P field or decimals - I understand it is because of the unicode conversion - but am still at los as how to resolve it...

Once again thoughts appreciated

Hi , it may help if I illustrate the changes made :

data statement

data:

begin of gs_mara,

matnr like mara-matnr,

VOLTO LIKE MARA-VOLTO,

end of gs_mara,

gt_mara like gs_mara occurs 10.

******************************

selection statement :

SELECT: MATNR VOLTO FROM MARA INTO CORRESPONDING FIELDS OF GS_MARA

WHERE MTART = 'RAW'.

APPEND gS_MARA TO gT_MARA.

ENDSELECT.

*********************************

this works fine but the transfer then fails and message below is received :

For the statement

"SEARCH itab FOR g"

only internal tables with a character-type row type are supported at

the argument position "LINE OF itab". Character-type data types are the types

N, D, T, and String, as well as structures that contain only the types

C, N, D, and T as components. Structures containing strings are not

supported. In the Unicode context, the type 'X', X-strings, or

structures that contain not only character-type components, are

regarded as non-character-type.

In this case, the internal table "LINE OF itab" has the non-character-type row

type "u".

******************************

Guess I've got some learning to do.

I'll take a better look tomorrow when I have a SAP system in front of me, but my suggestion would be that you create your structure with character fields and "write" any other fields into these e.g. something like

begin of gs_data,
  amount_char(20)        type c,
  volta_char(40)         type c,
end of gs_data,
*"... etc
select {some data} into corresponding fields of ls_mara
  from mara
  where mtart = 'RAW'.
write: ls_mara-volta to gs_data-volta_char left-justified. "or whatever
append gs_data to gt_data

endselect.

*"... etc
