SAP materials - Units of measure
Posted on 2005-03-22
My compnay is currently undergoing a SAP implementation and i am assisting with data migration from the legacy system.
We have a consultant who is advising on how to map our old data to SAP but I would like a second oppinion on the following:
We are a manufacturing engineering company and do a lot of work with sheet metal and other such raw materials.
Clearly these need re-creating in SAP with a base unit of measure. (and associated quantities on the bom's)
The consultant says that the base unit of measure should always be in the smallest unit that could be used
thus in the case of sheet material mm squared would seem like the answer.
We as an engineering company work to SI standards and so would like to deal in metres squared but
apparently sap can only handle 3 decimal places of precision
- equally it seems that we cant use mm squared because it will not allow BOM quantities large enough to handle
the square area of a large sheet if reffered to in mm squared.
He has suggested cm squared as the base unit of meausure but this seems like a very strange solution to what must be a
problem faced by many manufacturing companies.
An example part would be a 410mm x 360mm x 6mm thick sheet of steel.
If the consultant is correct then we couldnt do the obvious .410m x.360m = quantity of 0.1476
becuase would lose the last decimal place of precision
Could someone please offer a second oppinion on the matter
