T512W table — Wage Type Characteristics Table T512W

One row in T512W represents the full set of technical characteristics assigned to a single wage type, for a single country grouping, valid for a specific date range. This includes the permissibility indicators that control whether the wage type can carry an amount, a number, or a percentage rate, the unit in which a number is expressed, and the processing class and evaluation class values that downstream payroll schemas and evaluation reports use to decide how to treat the wage type during gross-to-net processing, cumulation, and reporting. The table does not store amounts paid to employees and does not store the wage type description. It answers a purely technical question: given this wage type in this country, what is it allowed to do and how is it classified for schema logic. Changes here affect every employee for whom the wage type is used, not just one record.

T512W is client-independent in the sense that country grouping, not client, is the real segmentation to filter on first; always restrict by MOLGA before LGART, since the same wage type code can carry entirely different characteristics in different countries. Always check BEGDA/ENDDA against the pay period or event date in question, because characteristics are time-delimited and an old row can still be sitting in the table with an end date in the past. The table is not large in absolute terms compared to master data tables, so full scans by MOLGA are cheap, but selecting by processing class value requires scanning the specific slot field, which is not indexed, so restrict by LGART or MOLGA first and inspect the result set rather than searching by class value directly.

Symptom: a wage type entered on basic pay is rejected with an entry not permitted style error, or a payroll result shows the wage type being cumulated into the wrong total. Selection: read T512W for the employee's MOLGA and the wage type in question, restricted to the date range covering the pay period, and check the amount/number/rate permissibility indicators and the relevant processing class slot value. If the indicator does not allow amount entry, or the processing class value does not match what the schema expects, the characteristics table, not the schema or the infotype, is the root cause.

T512W is unchanged in shape and continues to be maintained and read the same way on S/4HANA on-premise and in Employee Central Payroll, since core payroll schema logic still depends on processing class and evaluation class values stored per country grouping. There is no compatibility view replacing it because it remains an active configuration table rather than a transactional one. Consultants working across an SAP HCM to SuccessFactors Employee Central migration should expect this table to exist identically on both the legacy on-premise system and any Employee Central Payroll instance running the classic payroll engine.

This is payroll configuration territory, owned by the payroll or time management functional consultant, not basic data or integration teams. Any change request touching processing classes or evaluation classes should go through the person who owns the payroll schema, since a class value change here has direct downstream effect on schema logic that only that person can trace.

T512T carries the wage type description for the same MOLGA and LGART. Wage type characteristics are maintained through the standard wage type configuration view cluster in the IMG, not by direct table maintenance in a productive system. PA0008 and time evaluation output feeding wage types are the main consumers whose behaviour depends on what is defined here. Cumulation wage type configuration and valuation amount tables are maintained separately and should be checked alongside T512W when a wage type's total behaviour, not just its entry permissibility, is in question.
