从全球数据中获取价值

Question

How to identify the value contained in the following global variable, into lv_local variable?

data lv_local type string.

lv_local = '(SAPLMIGO)LCL_MIGO_GLOBALS=>KERNEL->S_CONTROL-VGART'.

Answer 1

You can assign the variable to a field symbol and read the value out of it. Example:

CONSTANTS: 
lco_migo_vgart_path TYPE string VALUE '(SAPLMIGO)LCL_MIGO_GLOBALS=>KERNEL->S_CONTROL-VGART'.

FIELD-SYMBOLS:
<migo_vgart> TYPE any.

DATA: 
lv_vgart TYPE vgart.

ASSIGN (lco_migo_vgart_path) to <migo_vgart>.
IF sy-subrc = 0.
    lv_vgart = <migo_vgart>.
ENDIF.

Be aware that accessing variables from the call stack like this is not ideal for productive usage, so looking for an alternative implementation is strongly recommended.
