When Entering a Sales Order getting message KIC180 You must enter company code error

[IanM_S4]

We are trying to set a new entity to complete Sales Orders, we have already had one entity set up by our SAP partner, but we trying to understand this ourselves

I have completed the steps detailed below but when I try to Enter a Sales order (VA01) at the header stage I get message “You must enter a company code for transaction Create sales document Message no. KI180” (SAP message KIC180 You must enter a company code for tr)

As I do not get this when I enter a Sales Order for our previous entity.

Can anyone advise where I should be checking as clearly, I have missed a configuration step, thank you

The steps I have completed are;

Sales Organisation definition     

1. Step 1-Create Credit Control Area - previously completed.
2. Step 2- Assign Company Code to Credit Control Area - previously completed.
3. Step 3- Define Sales Organization (IMG->Enterprise Structure->Definition->Sales & Distribution)
4. Step 4- Assign Sales Org to Company Code (IMG->Enterprise Structure->Assignment->Sales & Distribution)
5. Step 5- Define Distribution Channel (IMG->Enterprise Structure->Definition->Sales & Distribution)
6. Step 6- Assign Distribution Channel to Sales Organization (IMG->Enterprise Structure->Assignment->Sales & Distribution)
7. Step 7- Create Divisions (IMG->Enterprise Structure->Definition->Sales & Distribution)
8. Step 8- Assign Divisions to Sales Organizations (IMG->Enterprise Structure->Definition->Sales & Distribution)
