OBYC Tips / guides

What is OBYC? What can we achieve from this T-code?

OBYC is the place where we maintain the relationship between MM and FI. Ok, now to explain further. In MM, we have Valuation Classes which are assigned in materials. These Valuation Classes can be unique according to material type. Now SAP is designed in such a way that, for transactions that we execute which involves posting of an accounting entry relating to a material, it will check for this Valuation Class against a particular Key. This Key can be seen in OBYC and different Keys are assigned to different movement types.

In short, SAP determines the accounting entries by looking at Movement Type --> Key --> Valuation Class --> GL

Useful Tip / Guide

Scenario

Lets say you have an accounting document and you would like to find out which key is being used for the Debit and Credit side. Or when you have a situation lets say, a wrong GL is being used and you need to replace it with another, but you do not know exactly where in OBYC.

Solution

At the Accounting Document screen (FB03 or from Material Doc MB03 click on Accounting Document), click on change layout button. Then, add "Transaction" into the list of displayed columns. You will now be able to view the "Keys" associated to the debit and credit entry.

Hope this helps :)
