How To Fix RSRV201 - Check values of characteristic &1 for conversion exit

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 201

• Message text: Check values of characteristic &1 for conversion exit

Description
This test checks whether the characteristic that is being checked () use
s a conversion routine (synonym: conversion exit). (See transaction <AB>
RSD1 </>-> tab page <ZK>General</>.) A conversion routine converts
characteristic values from the external format in which the user enters
the data and in which the data is displayed, into the internal format in
which the data is stored on the database. Characteristic values have to
be available in the internal format in the master data table especially.
The most significant example is the ALPHA conversion exit. With an
<ZK>external -> internal conversion</> the ALPHA exit only changes
purely numerical values. In the target field, these values are
right-aligned. With an <ZK>internal -> external conversion</> leading
zeros are removed for purely numerical values.
If the characteristic is using a conversion routine, the system checks
all the values in the <AB>SID</> table of the characteristic to
ascertain whether they are valid internal values. By definition, the val
ues of the function module that the external -> internal conversion exit
takes are the valid internal values. In this test, the values are first
converted from the internal to external format and then back from the
external into the internal format. If the value obtained does not agree
with the original, it is not valid.
Note
Invalid internal values can cause problems in reporting. For example, if
several values in the master data table are converted to the same value
during the internal -> external conversion, the user cannot distinguish
between them. It may seem that duplicate rows appear in reports. It is
also possible that the user selects a filter value that seems to exist
in the result but finds no data for the filter value.
Repairs
It is currently not possible to perform repairs automatically in transac
tion <AB>RSRV</>. You use transaction <AB>RSMDCNVEXIT</> to perform
conversion for you entire SAP BI system. See SAP Note 447341 and the
<DS:DT.RSMD_CONVERSION>documentation</> about transaction
<AB>RSMDCNVEXIT</>.

  The SAP error message RSRV201, which states "Check values of characteristic &1 for conversion exit," typically occurs in the context of data extraction or reporting in SAP BW (Business Warehouse). This error indicates that there is an issue with the conversion of values for a specific characteristic, which may be due to incorrect or missing data in the InfoObject or the underlying data source.
  
  Cause:
  
  Data Type Mismatch: The data type of the characteristic in the InfoObject does not match the data type of the source data.
  Conversion Exit Issues: The conversion exit defined for the characteristic may not be able to handle certain values, leading to conversion errors.
  Missing Values: There may be missing or invalid values in the characteristic that cannot be converted properly.
  Inconsistent Data: The data in the source system may be inconsistent or not conforming to the expected format for the characteristic.
  
  
  Solution:
  
  Check the Characteristic Definition: Verify the definition of the
