FM to read buffer data

former_member462254 — Thu, 28 May 2015 10:36:26 GMT

my requirement is to read a data of a screen field.

Clear command has been used on a work area like 'clear: wa'. and just next to this line i wanna read the data of wa-field1.

=> solution

1. can declare a temp variable like wa-field1 and assign the wa-field1 data to this temp

=> expoert / import

=> parameter id---can't use hence wa-field1 is a z field

kindly suggest for the same...looking for a FM to read buffer data

if it is screen field data then go for assign field symbol

eg:lc_constansts type c--- (prgname)filedname

exampl;lv_filds type c30(sapmv45a)vbap-vbeln.

fieldsymbols:<lfs_vbeln> type vbeln.

to store the value so define like this

lw_field type vbeln.

assign (lv_filds) to <lfs_vbeln>

if sy-subrc is initial.

lw_field = <lfs_vbeln>.

endif.

for clear example:

constants:lc_xvbrp TYPE char20 VALUE '(SAPMV60A)XVBRP'

FIELD-SYMBOLS : <lfs_var> TYPE any ,

ASSIGN (lc_xvbrp) TO <lfs_var1>.

IF <lfs_var1> is ASSIGNED. "in case of normal call

lw_xvbrp = <lfs_var1>.

UNASSIGN <lfs_var1>.

endif.

Hi Anoop,

You can use FM DYNP_VALUES_READ to read the screen values in buffer.

Hi Anoop,

Since you already cleared that wa, where is buffer data come from.

So any concern if you declare a temp variable to store wa-field1? i prefer to use this.
