In PP01 Position there is option description there is one text field.
I need to change text at the time of saving through any user exit/ badi.
I searched BADI(HRBAS00INFTY), Method(BEFORE_UPDATE) Internal table field(tb_plog_tab-tdata) contain the text data.
But problem is that We can not change that data, this table is not changeable(tb_plog_tab).
Can any one help me in finding some user exit/BADI where I can change PP01-Description-text field before saving.
