Derive 0OBJ_CURR from 0COST_CENTER master data in customer exit

Question

Hi,
I'm having trouble with the syntax in the following case:
I'm trying to create a customer exit variable for reporting which is reading the cost center value from cost center variable (ZIPCC) and then using that value to determine the home currency of that cost center by reading the 0OBJ_CURR field from cost center master data.
The code is as follows:
DATA D1 Like 0OBJ_CURR.
remark: Object currency is unit. How to declare units?
WHEN 'ZIPCUR'.
if I_STEP = 2.
loop at i_t_var_range into lt where vnam = 'ZIPCC'.
Select single OBJ_CURR into D1 from /BI0/PCOSTCENTER where COSTCENTER = i_t_var_range-low.
remark: I'm having also trouble with the selection of OBJ_CURR.
clear l_s_range.
l_s_range-low = D1.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
append l_s_range to e_t_range.
endloop.
endif.

Answer 1

Found the answer, to bad i cannot give points to myself :-P
In the ABAP i use the E_T_RANGE output structure.
That structure has several fields (sign, opt, low, high).
In my ABAP i stored the same value in the low and high field.
This should work fine for normal (flat) characteristic values.
However, because i use a hierachy i should enter the 0HIER_NODE value in the high field.
