read memory doesn't work with badi ??

[Former Member]

I had a sollution in an user exit for goods movement to read the memory of the screen since I had to check the changed data before saving.

it works perfectly so now I thought I could also use it in a badi but somehow it doesn't work and it can't read the programm memory .

this was my code from the user exit of IW42

data: global_field_name(100).
data: artikel type structure occurs 0 with header line .

DATA: BEGIN OF gt_comp OCCURS 0.
        INCLUDE STRUCTURE cowb_comp.
DATA: END OF gt_comp.

field-symbols : <fs> type any table,
                <wa> type any.



clear global_field_name.
move '(SAPLCOWB)GT_COMP[]'  to global_field_name.
assign (global_field_name) to <fs>.


* functie moet alleen werken indien het element alwaar terugmelding op gemaakt wordt een serviceorder is
* en via totale terugmelding IW42 wordt ingevoerd
if caufvd_tab-aufnr is not initial and sy-tcode EQ 'IW42'.

loop at <fs> assigning <wa>.
move <wa> to gt_comp.
if gt_comp-rsnum eq '0'.
    message ID 'ZCS' type 'E' number '001'.
endif.
endloop.

which works fantastic

now I tried to translate it to the badi and it doesn't work at all. the error <fs> is not assigned is raised. somehow the trick is differently in a badi or in a method to read something from memory

the purpose is that I only need to perform the check when the status is set to AFSL

so I try to read the structure CNJ_STAT from memory which is the programm SAPLCJWB

data: h_error type string.

data: global_field_name(100).
data: gt_cnj_stat type table of cnj_stat.

field-symbols : <fs> type any table,
                <wa> type any.



clear global_field_name.
move '(SAPLCJWB)gt_CNJ_STAT[]'  to global_field_name.
assign (global_field_name) to <fs>.

if <fs> is not initial.
loop at <fs> assigning <wa>.
move <wa> to gt_cnj_stat.
endloop.
endif.

anybody got a clue what is wrong which the assignment ?

Give the name of the TAB in the Upper Case. Try like:

move '(SAPLCJWB)GT_CNJ_STAT[]'  to global_field_name.

nop that didn't work.

but I figured it out finally since I saw in debugging the global vars and the values of CNJ_STAT I saw that the defenition was a flat structure although I would have thouught a table would be the case.

so with this coding it works now

field-symbols : <fs> type any table,
                <wa> type any.



clear global_field_name.
move '(SAPLCJWB)CNJ_STAT'  to global_field_name.
assign (global_field_name) to <wa>.

thanks for the input

i can see here one

'(SAPLCJWB)gt_CNJ_STAT[]'

Try this way.use all caps.

'(SAPLCJWB)GT_CNJ_STAT[]'

Hi,

Please do it in this way.

FIELD-SYMBOLS: <FS> TYPE ANY.
ASSIGN(')SAPLCTJDW)PSTAB') TO <FS>.

Thanks,

why is that the way to do it Chidanand Chauhan ? is there a reference somewhere where the recomended coding is described ??

kind regards
