How to fix this error?

Enter at least one allocation to a purchasing document, so that the
system can determine the supplier. To do this, choose the tab page
<LS>PO reference</> and enter the document number. At least one purchase
order item must be selected for settlement before you can post to G/L
accounts and material accounts.
You choose the tab page required:
<LS>G/L account</>
<LS>Material account</>
Then you enter data as required.
<ZH>Note:</>
If you create a supplier invoice with a purchase order reference, the
system takes over the supplier automatically from the purchase order.
But if you create a supplier invoice for a G/L account item only (with
no purchase order reference), you have to enter the supplier in the
header before you can access the <LS>G/L Account</> tab.
