Get this error.

Price Tax authority does not form part of the customer group tax authority.

Tried creating order in OE and came up with this.

So did some clean up by removing tax authority in Price List, Customer Group and item wizard. Same error after sync.

Found the item had two units of measure with the same conversion rate. Removed one but still same.

Deleted PR. Left MT as the stocking unit.

So can now enter an order in OE without an error. But same error in POS.

Any suggestions please?
