How To Fix KO331 - No business area is assigned to the material

SAP Error Message - Details

• Message type: E = Error

• Message class: KO - Master data for CO orders

• Message number: 331

• Message text: No business area is assigned to the material

What causes this issue?

You specified that a business area balance sheet is to be generated for
the <DS:GLOS.3526B800AFAB52B9E10000009B38F974>company code</> of the
<DS:GLOS.3526B6F2AFAB52B9E10000009B38F974>product cost collector</>.
However, the system was not able to derive a
<DS:GLOS.3526B86CAFAB52B9E10000009B38F974>business area</> for the
product cost collector. The business area is determined by the
<DS:GLOS.3526C7E1AFAB52B9E10000009B38F974>division</> that the material
is assigned to.
There are two places in Customizing where you can maintain the
assignment of a division to a business area:
For revenue postings in the SD module, you assign a business area to
the combination: Plant and division.
For material postings in the MM module, you assign a business area to
the combination: Valuation area and division.

How to fix this error?

Check whether a business area balance sheet is in fact intended in the
company code of the product cost collector.
To do this, go into Customizing.
Check whether the material is assigned to a division.
<DS:TRAN.MM03>Display material master record</>
Check whether the division has been properly assigned to sales, plant,
company code, division and business area.
If not, go to Customizing and choose: <ls>Enterprise Structure ->
Assignment -> Logistics-General -></> <ls>Data Comparison With Sales
Plant/ValArea-Div- BusArea</>. On the <ls>Missing Business Areas for
Valuation Areas</> screen, choose the function <ls>Create Entries for
Valuation Areas</>.
