acking Up Table T512W (Wage Types)
Use
We generally recommend backing up wage types table T512W before upgrading. However, in the following cases, you must back up table T512W:

You have modified 'technical' wage types, that is wage types beginning with '/' (adjustment of processing class, evaluation class, and so on).
You are using SAP model wage types, that is wage types beginning with a letter, and you have modified these.
You have defined wage types that are not within the customer name range. To find out if this applies, check table TRESC by entering T512W as the table name and TABU as the object.
Procedure
Note
Read SAP note 447984 and implement SAP note 605878 before the upgrade.
Before the upgrade, back up table T512W or selected areas of this table. To do this, use report RPU12W0S. The documentation on the report includes instructions on how to proceed.

Note
Table T512W is client-specific. Make sure you back up the data in the correct client.
You can restore your backup copy after the upgrade. To do this, you can use the following reports:
RPU12W0C restores selected parts of table T512W. This method is particularly suitable if you have exact documentation about the wage types you have modified.
RPU12W0S restores the entire backup or a generically selected area of the table.
