Runtime Modifications during Z table maintenance (screen flow logic)

Former Member — Thu, 28 Jun 2007 11:39:40 GMT

I have created a custom t-code for table maintenance of a custom table. This table has a count field which needs to be auto generated during the maintenance (each time a new record is added, the counter is incremented as per the key field value)

Hence I am modifying the PAI of the overview screen to generate the counter value. I have been able to copy the "extract" table into an internal table and modify the count field. But I do not know how to put back these changes to the "extract" table. Any help in this regard would be really helpful.

Below is the module code:

MODULE modify_count INPUT.

TYPES:

BEGIN OF t_gtin,

zzisgtin TYPE zgtinaudit-zzisgtin,

END OF t_gtin,

BEGIN OF t_count,

zzisgtin TYPE zgtinaudit-zzisgtin,

zzcount TYPE zgtinaudit-zzcount,

END OF t_count.

DATA:

primtab_mod TYPE REF TO data ,

i_zgtinaudit TYPE zgtinaudit OCCURS 0,

i_gtin TYPE TABLE OF t_gtin ,

i_count TYPE TABLE OF t_count ,

wa_zgtinaudit TYPE zgtinaudit ,

wa_gtin TYPE t_gtin ,

wa_count TYPE t_count ,

v_zzcount TYPE zgtinaudit-zzcount ,

v_okcode TYPE sy-ucomm ,

v_idx TYPE i.

FIELD-SYMBOLS:

<table_entries> TYPE STANDARD TABLE.

v_okcode = sy-ucomm.

CHECK v_okcode EQ 'SAVE'.

CREATE DATA primtab_mod TYPE TABLE OF (x_header-maintview).

ASSIGN: primtab_mod->* TO <table_entries>.

Move the data in the table control to <table_entries>

LOOP AT extract.

APPEND <vim_extract_struc> TO <table_entries>.

ENDLOOP.

MOVE <table_entries>[] TO i_zgtinaudit[].

SORT i_zgtinaudit BY zzisgtin DESCENDING.

Store the key field (GTIN) values

LOOP AT i_zgtinaudit INTO wa_zgtinaudit.

wa_gtin-zzisgtin = wa_zgtinaudit-zzisgtin.

APPEND wa_gtin TO i_gtin.

ENDLOOP.

SORT i_gtin BY zzisgtin.

DELETE ADJACENT DUPLICATES FROM i_gtin.

Select existing data from the table for the GTINs

SELECT zzisgtin

zzcount

FROM zgtinaudit

INTO TABLE i_count

FOR ALL ENTRIES IN i_gtin

WHERE zzisgtin EQ i_gtin-zzisgtin.

IF sy-subrc EQ 0.

SORT i_count BY zzisgtin zzcount DESCENDING.

ENDIF.

Generate the counter

LOOP AT i_zgtinaudit INTO wa_zgtinaudit.

v_idx = sy-tabix.

IF NOT wa_zgtinaudit-zzisgtin IS INITIAL.

AT NEW zzisgtin.

CLEAR:

wa_count,

v_zzcount.

READ TABLE i_count INTO wa_count

WITH KEY zzisgtin = wa_zgtinaudit-zzisgtin.

IF sy-subrc EQ 0.

v_zzcount = wa_count-zzcount.

ENDIF.

ENDAT.

v_zzcount = v_zzcount + 1.

IF wa_zgtinaudit-zzcount IS INITIAL.

wa_zgtinaudit-zzcount = v_zzcount.

ENDIF.

IF wa_zgtinaudit-zzisauditusrid IS INITIAL.

wa_zgtinaudit-zzisauditusrid = sy-uname.

ENDIF.

MODIFY i_zgtinaudit FROM wa_zgtinaudit INDEX v_idx.

ENDIF.

ENDLOOP.

REFRESH <table_entries>[].

MOVE i_zgtinaudit[] TO <table_entries>[].

ENDMODULE. " modify_count INPUT

Hi,

I think there is no need of dumping data into an internal table you can just read the maximum count value from the extract table as below.

READ max(zzcount) INTO wa_zzcount FROM extract.

and then assign it to table field value.

wa_zzcount = wa_zzcount + 1.

<table>-zzcount = wa_zzcount.

I haven't checked but i think it will work.

Reward points if usefull.

thanks,

Muthu.

Hi,

Use select max( field name (i.e,counter value) ) from database table into counter.

case 'ok_code'.

when 'funct. code.'

then increment the counter assing the incremented counter value to ITAB-fieldname.

if sy-subrc = 0.

modify itab index sy-tabix.

else

append itab

insert DBtable name from table itab.

refresh itab

endif.

endcase.

use this method it will work.

Reward if helpful
