Problems with Var. Bucket Consumpt. field in PPMs

Question

Hi experts,
I'm trying to manually create a PPM (Production Process Model) into APO (to use it with SNP), however, the value entered in the
Bucket Consumption (Variable) field disappears when I active the PPM. Someone could tell me what I am doing wrong?
First, I created a Resource ( using fields of tab 1 Bucket ) with the following data:
Resource
Resource: R
Category (Cat): P - Production
Location: L
Time Zone: BRAZIL
Bucket Dimensn: Mass
Factory Calendar: BR
Bucket Capacity: 96000
Unit: KT - Kilotonne
Number of Periods: 365
Period Type: Day
Days -: 1095
Days +: 1095
ie, a resource with a capacity of 96000 Kilotonne per year.
The PPM I'm trying to create is the following:
PPM's General Data
Use of a Plan: S - PPM for Supply Network Planning (SNP)
Variable (Single Level Costs): 980,00
PPM's Operations and Activities
Operation: 0010:Produce
Activity: 10:Produce
Components of Activity
Product          I/O Indicator     Consump. Type     From Date     To Date          Unit     Var. Consumptn
A          O          E          01.01.1970     31.12.9999     KT     1000
B          I          S          01.01.1970     31.12.9999     KT     560
C          I          S          01.01.1970     31.12.9999     KT     180
D          I          S          01.01.1970     31.12.9999     KT     260
Mode of Activity
Mode     Primary Resrce          Location     Unit     Fix. dur.
10     R               L          D     4
Resource Mode
Resource     Location     Unit     Var. Bucket Consumpt.
R          L          KT     1000 (here is the problem)
PPM's Model
Prod. Process Model     Output Product     Date From     Date To          Planning Locatn     Discretization     Maximum Lot Size
PPM_1               A          01.01.1970     31.12.9999     L          x          9999999
ie, a PPM to produce 1000 KT of A in 4 days that consumes 1000 KT of R resource capacity.
The value of 1000 KT in the field Var. Bucket Consumpt. is not allowed. I could only register values between 0 and 9.
Thanks in advance for help.
Greetings,
Francisco Fonseca.

Hi,
Its a good practice that when you make PPM manually keep fixed duration as '1 Day' (in your mode of activity).
One thing i noticed that you made your resource as bucket resource, which is correct,
but the number you mentioned there (Bucket Capacity: 96000) is not right. What is the unit? It  should be in hours (should be 8 or 9 or ).
That means in One day the resource is capable of producing goods for 8/9/ Hours. So, make the change there.
Now in your Mode of activity make fix  duration  1 Day.
Components of Activity
Product          I/O Indicator     Consump. Type     From Date     To Date          Unit     Var. Consumptn
A          O          E          01.01.1970     31.12.9999     KT     1000
B          I          S          01.01.1970     31.12.9999     KT     560
C          I          S          01.01.1970     31.12.9999     KT     180
D          I          S          01.01.1970     31.12.9999     KT     260
Mode of Activity
Mode     Primary Resrce          Location     Unit     Fix. dur.
10     R               L          D     1
Now in resource: put following value
Resource Mode
Resource     Location     Unit     Var. Bucket Consumpt.
R     L     H          1     
You will get an output as 8000 or 9000 (depending on your resource capacity per day, ie 8hr or 9 hr  )
and if you put Variable consumption as 8/9 hrs the you will get 1000 KT per day, in that case you put variable material/product consumtion as 250 KT,
so you can get 1000 KT per four day. Variable resource consumption responsible for variable output (variable consumption of FG).
Pls revert if still there is any issue.
