How To Fix HRPFD00004 - Data type of key was changed; no conversion possible

SAP Error Message - Details

• Message type: E = Error

• Message class: HRPFD00 - HR-PF: International Pension Fund

• Message number: 004

• Message text: Data type of key was changed; no conversion possible

What causes this issue?

The data type of one of the two reference value types (which can be
defined as keys in parameter table T5CAD) has been changed. The data
types are incompatible, which prevents an automatic conversion from
taking place and means that inconsistencies could arise when parameters
are maintained.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Undo your change of data type for the reference value type and delete
your parameter values. You can then recreate the parameters using the
new data type.
You can also delete the data using view V_T5CAD_PB. In this case, you
do not need to undo the change of data type.
