SAP Message RSRV198 - SID table contains &2 values with wrong internal format

Diagnosis
Characteristic &V1& uses a conversion exit to convert values from anexternal format used to display the data to the customer, into aninternal format used to save the data on the database.
The test has determined that there are values in the SID table forcharacteristics &V1& &V2& , that are not in the correct internalformat. If the characteristic is compounded, the values of thesuperordinate characteristics can use the conversion exits in certaincircumstances. In this case, the number of incorrect characteristic
values can differ from the number of incorrect data records. The testrun has determined that &V3& data records in the SID table areincorrect. If you corrected the data by converting it first intoexternal and then back into internal format, &V4& data records wouldlose their unique characteristic value key.

Procedure
For the conversion exits ALPHA, GJAHR and NUMCV, you can convert thecharacteristic values in to the correct format in transactionRSMDCNVEXIT and replace them wherever youuse them.
