SAP error messages, explained
The messages that stop you mid-ticket — what SAP is actually telling you, why it happens, and how to fix it. No jargon, no SAP Note login required.
Deficit of stock
SAP will not let you move or issue this material because the quantity you asked for is not available in that exact stock situation.
Posting period ### / #### is not open
The period your posting date falls into is closed, so SAP refuses the document.
Balance in transaction currency
Your document does not balance: total debits do not equal total credits.
Account determination for entry ... not possible
SAP knows it must post an accounting document for your goods movement, but no G/L account is configured for that combination.
Item category ... is not defined / not allowed
SAP cannot determine a valid item category for the item you are adding to the sales document.
You are not authorized to ...
Your user is missing an authorization object value needed for what you just tried to do.
Balancing field "Profit Center" in line item ... not filled
Document splitting is active and a required split characteristic (usually profit center or segment) is missing on a line.
