How To Fix FH056 - Account creation not possible since a cost element already exists

FH056 - Overview

• Message type: E = Error

• Message class: FH - General ledger module messages

• Message number: 056

• Message text: Account creation not possible since a cost element already exists

What causes this issue?

You are trying to create a G/L account for which a secondary cost
element has probably already been created. If this is the case, it is
not possible to create a G/L account for the same number.

System Response

The program cannot create a G/L account with this number.

How to fix this error?

Check the G/L account number used, and change it if necessary.
If the G/L account number is correct, check whether a cost element has
already been created with the same number and check which cost element
category has been used. You may need to use new numbers here. If the
existing cost element is a primary cost element type, then the status of
the relevant tables is incorrect because primary cost elements can only
be created with G/L accounts that already exist.
