ooops i forgot:)
there are two ways now.
- you set lv_flag as 'x'.
import lv_flag to lv_flag from memory id 'ZABC'.
if lv_flag is initial.
message.
lv_flag = 'X'.
export lv_flag from lv_flag to memory id 'ZABC'.
endif.
2. in your implemnting class add a static attribute and set it inside you code it will work in same as told ealier.
