ERROR ON RECIEVING No. SERIES IN PURCH. INVOICE

If I try to Post the PURCHASE INVOICE an ERROR Appear

“You must Specify Recieving No. series In Purchase header Document type =‘Invoice’,No=‘RR00001’.”

I hope you can help me. TY[:)]

Check Purchase & Payable Setup. You will likely find the boolean field “Receipt on Invoice” checked. If this is the case, you need to assign a Numbering Series to Posted Receipt on the Numbering tab. If you uncheck the field the invoice number will be used to post the receipt.
