Independent requirement for KANBAN Calculation

Question

Hi all guru,
Now i can use kanban caculation for Semi-FG (it use dependent requirement for calculate) and i want to calculate FG too! but i don't know how to configure to use independent requirement (forecast) for automatic kanban calculation. who expert know please explain to me?
Thank you in advance...

Answer 1

Kanban Calculation takes place for requirements at a control cycle      
level, specifically at a supply area level.The kanban calculation can   
therefore be only carried out for dependent requirements that refer to a
supply area. This supply area is usually assigned to the BOM item but   
also can be defined in production version or material master.  
Please refer the following documentation:

  Logistics

I am afraid, independent requirements(PIRs in MD61) entered and also    
sales order requirements can only be tracked at a plant level, and hence
cannot be included for Kanban calculation. On the same lines the        
dependent requirements that are defined only at a storage location level
are also not included!                                                                               
In fact KANBAN scenario is suitable for the business where the          
procurement need not be planned well in advance, all procurement can be 
initiated at any time once KANBAN is empty. This is the most important  
characteristic of KANBAN. The introduction of PIRs into this scheme     
contradicts this very objective of 'avoiding' lead times in planning.   
This is also the reason why KANBAN calculation is more appropriate for  
dependent requirements from supply area, characteristic of most         
automotive industries, where make-to-stock planning happens mostly at
higher Sub-assembly levels and not at component levels.                 
Kanban is more relevant to only one subset of MRP requirement elements  
i.e, the Dependent requirements.                                                                               
Also, incase you want to include all storage locations / supply areas   
in the plant for the control cycle in question,then in PK02, for the    
said control cycle , under Kanban calculation tab, click on "Additional 
Requirements Button" and enter the plant (without the storage           
location/supply area). In this case,the automatic kanban calculates all 
the dependent requirements in the plant.
In automotive releases we have the BADI MPKC_REQ_SELECTION             
hooked in the function module PK_READ_DEPENDENT_REQUIREMENTS.
Customers, who want additional requirements such as the ones from APO to
be included for calculation, can program here.                                                                         
Production Supply area is the key for the requirements to match with the
control cycle. Hope I have clarified your query.
