T-code of the day

One SAP transaction code. Four characters, six guesses, a new one every day.

How it works

Type any four characters, letters or digits, and press Enter.
A filled violet tile is the right character in the right place. A dashed amber tile is in the code, somewhere else. A grey tile is not in it.
You are told the SAP area from the start, and what the code does after three guesses.
Every answer is a classic transaction code people type into the SAP GUI command field.
Stuck? F4 lists the possible entries for today's area, as the value help does in SAP. Solving without it is the harder game.

SAP transaction codes by area

A transaction code, or T-code, is the short code typed into the SAP GUI command field to open a transaction: VA01 creates a sales order, SE16 opens the Data Browser. These are the classic four-character codes the puzzle draws from, grouped by SAP area, each with what it does; each area's full list, with the longer codes, has a page of its own.

It is a working set, not a catalogue: an SAP system holds tens of thousands of transaction codes, and SE93 shows any of them. Most of these still work in SAP S/4HANA on premise and in the private cloud edition; where one was replaced, the line says so. The public cloud edition has no command field, and the same tasks are Fiori apps there.
