Read variables from higher-level stack programs or use them! Dirty Assign?

former_member284704 — Mon, 27 Nov 2017 11:47:59 GMT

data: it_abap_callstack type abap_callstack.
data: it_syst_callstack type sys_callst.

    call function 'SYSTEM_CALLSTACK'

      exporting

        max_level    = 20

      importing

        callstack    = it_abap_callstack

        et_callstack = it_syst_callstack.



I try to get the data from the local table like this:

       field-symbols: <fs_table> type any table.

       assign ('(FBICRC003_DATA_REC)LT_SEL[]') to <fs_table>.


But the table is not assigned, could anyone help me out?

You can't access local data only by using this methodology (only global data). A workaround is to use the Enhancement Framework, by defining a global field symbol (for instance named <ZZ_GT_SEL> in program FBICRC003_DATA_REC, and assign LT_SEL to it at the beginning of the procedure where LT_SEL is defined, then use assign ('(FBICRC003_DATA_REC)<ZZ_GT_SEL>') to <fs_table>.

PS: of course, before doing the latter assign, you have made sure that the procedure declaring the local data object (MAIN of FBICRC003_DATA_REC) exists in the call stack, otherwise a short dump would occur.
