Changing the Supplier and Account number

If you change Supplier, you need to update the Account number and the Contract in Sigma.

Open Estate Management Activity

• Click on the Supply Point Tab 
• Highlight the Supply Point
• Check that the old Account number shows in the Related Items section

The Change Contract popup appears

• Change the date to the date you want the Account number changed
• Do NOT change the Contract from the dropdown (in this example it is only the Account number that has changed, not the Supplier)
