Parallel Routings / Parallel Production

Hashim Abbasi

Hi,

 

I have a scenario where Production is taking place in such a way that when 10 pieces of a say Material A are produced the processing for the next level i.e. Material B starts and so on. The issue is that the system schedules the order in such a way that when the entire order of Material A is produced only then the production of Material B starts while in actual the Material B starts after 10 units of Material A have been produced. The order quantity is 100, it takes 1 hour to produce 10 units of Material A and 1 hour to produce 10 units of Material B. The system calculates that it will take 20 hours to produce both A and B while in actuality it takes 11 hours.

 

My question is how can we make the system automatically schedule Production this way. We are using discrete manufacturing, stock level and transfer needs to take place between materials so we can not use collective orders.

 

Regards,

HA

    Dear Hashim,

    I feel you are talking about the overlaaping of production.

     

    Suppose you are having production order of 100 Pcs for material A.

     

    Now initially on wrok center 1 you processed 10 pcs(i.e. components to produce 10 pcs of material A)  of material A then moved those 10 pcs to work center 2. Then again next 10 pcs of material A are loaded over work center 1 & so on.

     

    If this is the case then please go for overlaaping of operations in routing. Please go to operation details. Enter Overlap time & minimum send ahead quntity for all operations so that you will find the precise scheduling time for your production orders.

    Hi,

     

    Scheduling of production orders as a second step after MRP run is possible. However this is not automatically done in SAP. This usually has to be done for capacity considerations. Capacity leveling when performed after MRP by the shop floor controller determines the real schedule which is valid in terms of capacity. For this explore Capacity Requirement Planning topic and transactions in SAP menu, or reshedule produciton orders manually with realistic hours.
