Rounding the purchasing quantity

Question

Hi
i am having a reqirement to round my purchasing quantity.
we procure the material in bags.
1 bag = 1000  kg
if my reqirement exceeds 1000 kg it the the purchasing quantity should be 2 bags = 2000 kg.
how should i do this
right now. if my reqirement is 1200 kg its coming out as 1.2 bags in my Purchase order./
i think i have to maintain a rounding profile for that,
can some one explain me how to maintain a rounding profile for this case

Answer 1

There are many solution if you are running MRP to create PR
1.
You can maintaina lotsize key as FX in MRP 1 view and fixed lot size as 1000.
Then even if the reqiuirement is 1200, system will create a PR for 2000.
Above solution is okay if you are running MRP.
2.
Use rounding Profile in MRP1 view. example form SAP help
A material's base unit of measure is 1 unit; the purchase order is to be
delivered in layers (1 layer corresponds to 5 units) or in pallets (1  
pallet corresponds to 8 layers which contains 40 units).                                                                               
You maintain the profile as follows:                                   
From a requirements of 2 units, the system is to round up to 5; from a 
requirement of 32 units, the system is to round up to 40.                                                                               
This results in the following order proposal quantities:               
Requirement from 1 -> 1     requirement from 31 -> 30                  
Requirement from 2 -> 5     requirement from 32 -> 40                  
Requirement from 6 -> 10    requirement from 74 -> 80                  
Requirement from 7 -> 10
