Hi experts,

Which system variable(sy-xxxx) can be used to get the processing line number of an internal table in a loop?

Thx in advance.

Points will be rewarded.

Hi Priyank,

yes. SY-TABIX.

But becareful that the sy-tabius hat not been changed by i.e. a form call,

loop at itab.
  perform anything.
* usage of sy-tabix is dangerous because it may have been changed by anthing
endloop.

Better:


data: lv_tabix type sytabix.
loop at itab.
  lv_tabix = sy-tabix.
  perform anything.
* usage of sy-tabix is dangerous because it may have been changed by anthing
* but using lv_tabix is fine
endloop.

Clemens

Hi,

SY-TABIX

Current line of an internal table. SY-TABIX is set by the statements below, but only for index

tables. The field is either not set or is set to 0 for hashed tables.

Hi,

SY-TABIX will change only if you use some APPEND or DELETE or INSERT statments in the loop, if you call a sub routine it will not have any effect.
