Enhancement for Version Long Text in ME21n/22n/23n

[Former Member]

Requirement :

To provide the comments/information with more than 1000 characters  for the New Version triggered.

Procedure :

Step-1 : Check the feasibility to add  a function button on the ALV Tool bar for populating the Text Editor Dialog Box for the requirement.

Step-2 :Using Implicit Enhancement Enhanced the ALV Tool bar with a ICON and handle the SY-UCOMM in Version TAB in Purchase Order (Create/Change/Display) Screen.

Step-3 : In INCLUDE LMEDCMVCI1 we have Standard Class LCL_DCM_GRID implemented.  The below code is useful to add an ICON in Method TOOL BAR_INIT to provide the feasibility to hold the Text Editor Pop up.

if sy-tcode = 'ME22N' OR SY-TCODE = 'ME23N' OR SY-TCODE = 'ME29N'.

l_quick = 'Version Long Text'.

CALL METHOD cl_gui_toolbar=>fill_buttons_data_table

    EXPORTING

      fcode            = '&LONG_TEXT'

      icon             = icon_document_revision

*  DISABLED         =

      butn_type        = cntb_btype_button

*   TEXT             =

      quickinfo        = l_quick

*  CHECKED          =

    CHANGING

      data_table       = lt_my_buttons

    EXCEPTIONS

      cntb_btype_error = 1

      OTHERS           = 2.

IF sy-subrc = 0.

APPEND LINES OF lt_my_buttons TO ch_buttons.

ENDIF.

ENDIF.

The above code explains that the FUNCTION CODE for the ICON on the ALV Toolbar is defined as 'LONG_TEXT'.

Step-4 : Using the Function Code "LONG_TEXT" handled the functionality for populating the TEXT EDITOR dialog box , by enhancing the method EXECUTE_BEFORE_TRANSPORT where all the standard function codes are handled.

The executed code is mentioned below.

>> Check if there Version Management is having  any other Version rather than ZERO.

Else through a Information Message that "Initial Version is only exist".

CASE im_fcode.

      WHEN '&LONG'.

*        .list change documents caused by selected revisions

     DATA: lt_models      TYPE mmpur_models,

           ls_models      LIKE LINE OF lt_models,

           ls_erevitem    TYPE erevitem,

           l_rev_item     TYPE REF TO if_revision_item_dcm,

           l_edokp        TYPE erev-edokp,

           l_num_min(8)   TYPE n,

           num_min(8)   TYPE n,

           l_num_max(8)   TYPE n,

            C TYPE C.

     CHECK NOT my_manager IS INITIAL.

     CALL METHOD get_selection

       IMPORTING

         ex_models = lt_models.

     IF lt_models IS INITIAL.

    MESSAGE I001(Zlng).

    exit.

     ENDIF.

b) If we have a New Version rather than ZERO, Then pick the Selected Line Item for which the Long Text should be maintained .

LOOP AT lt_models INTO ls_models.

       mmpur_dynamic_cast l_rev_item ls_models-model.

       CHECK NOT l_rev_item IS INITIAL.

       ls_erevitem = l_rev_item->get_data( ).

*-- Portability: REVOK is space or numeric

       l_num = ls_erevitem-revno.

       l_num_min = l_revno_min.

       l_num_max = l_revno_max.

       IF l_num LT l_num_min

       OR l_revno_min IS INITIAL.

         l_revno_min = ls_erevitem-revno.

         l_date1     = ls_erevitem-erdat.

         l_time1     = ls_erevitem-eruhr.

       ENDIF.

       IF l_num GT l_num_max

       OR l_revno_max IS INITIAL.

         l_revno_max = ls_erevitem-revno.

       ENDIF.

     ENDLOOP.

C) Create a Custom Function module ZMM_LONG_TEXT where we need to handle the functionality with

IMPORTING Parameters :

--> Maximum Version Line Items

--> HEADER ,

--> Current Line Item Selected for the Version Long Text

and

--> System Transaction code

Functionality of the Function Module :

• Step 1 : Go to SE75 Transaction. Click on change button, Now create Text Object ZVER_LONG.
  Enter the name & Description of Text object. Here in this case, save mode is selected as update because comments data is need to be updated against each development objects table entry In editor ,Editor application is of type Standard Text(TX) and line width is 72 which can be selected as per requirement.
  Style and Form can also be selected from this window, which will decide the display style of text.
  Once the object is being created, double click on the text object.
• Step 2 : Create Text ids' .In this scenario, '0001' text Id is created.
• Step 3 : Once the text ids will be created, front end work is done.

• READ_TEXT - To retrieve Long Text from Text Objects.
• SAVE_TEXT - To save Long Text into Text Objects.

Test Case :

>> 1) Open The Purchase Order (ME21n/ME22n/ME23n) & navigate to Version Tab as mention below

>> 2) Select the Line Item for which the Long Text should be maintained and

         Click on the Long Text ICON as shown below

>>3) Now u can able to Create/Change/Display the Version Long Text maintained
