Three variable functions ( VARV, VARC, VARI ) in FOXformula.

In Fox formula (planning funtion type 0RSPL_FORMULA), there are threefunctions for variable: VARV, VARC, VARI. Let's use some examples to knowhow to use it.

1. VARVMeaning: Get a variable value.

: Usage example

PLANT = VARV(0S_PLANT).

The PLANT will get the BW variable 0S_PLANT value.

VARV cannot get more than 1 values. When 0S_PLANT contains a range which includes 2 or more than 2 values, the following kind of error willbe seen:

Variable 0S_PLANT has to be restricted to a single value

Message no. RSPLF004

2. VARCMeaning: Get the number of values of a variable.

Usage example:

N_PLANT = VARC(0S_PLANT).

The N_PLANT will receive the number of variable 0S_PLANT values.

VARC can calculate the combination of multiple single values and ranges.If 0S_PLANT contains the combination 0001 - 0002; 0003 - 0004; 0005;0006, the N_PLANT will contain 6.

3. VARIMeaning: Get the N-th variable value.

Usage example:

I_PLANT = VARI(0S_PLANT, 2).

The I_PLANT will receieve the 2nd value of variable 0S_PLANT.

VARI also can calculate the combination of multiple single values and ranges like VARC. The system sorts all of the variable values beforeselecting.

If 0S_PLANT contains the combination 0001 - 0002; 0003 - 0004; 0005; 0006, the I_PLANT will contain 0002.

These three variable can also work for hierarchy node variable.Usage example:

HN_PLANT = VARV( ZHN_PLANT, HIENM = ZH_PLANT, DATETO = ZDATETO ).CT_PLANT = VARC( ZHN_PLANT, HIENM = ZH_PLANT, DATETO = ZDATETO ).

N_HN_PLANT = VARI( ZHN_PLANT, HIENM = ZH_PLANT, DATETO= ZDATETO, 2 ).

ZHN_PLANT is a hierarchy node variable.

ZH_PLANT is a hierarchy variable.

ZDATETO is a single value variable for characteristic 0DATE.

There is a time-dependent hierarchy named , which is valid from to .ZPLAN_1 01.01.2013 31.12.2013

Hierarchy structure is:

0001 -> 0002

-> 0003 ->0004

->0005

When ZHN_PLANT is node 0003, ZH_PLANT is ZPLAN_1 and ZDATETO is 31.12.2013, the result will be:

1) There is error RSPLF004 for ZHN_PLANT and HN_PLANT cannot get any value, because there are three values for node 0003(value 0003, 0004, 0005).

2) CT_PLANT = 3.

3) N_HN_PLANT = 0004.
