How To Fix CNV_10020484 - Generation of analysis program for table &1 has failed

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 484

• Message text: Generation of analysis program for table &1 has failed

What causes this issue?

Internal generation of the analysis program for table &V1& has failed.

How to fix this error?

The most likely reason for the generation error is that the
CNV_10020_DTFLD entries you want to analyze were maintained
incorrectly. Check these entries and repeat the generation.
&HINTS&
The analysis programs are generated internally during the org.
analysis, but not stored in the database.
If you set the package parameter WRITE_PROGRAMS_ON_DB to 'E' in
transaction CNV_10020_PARAM, programs for which errors occurred during
generation are stored in the database so that you can analyze them. You
can delete these programs again using transaction CNV_10020_DELREP.
Alternatively, you can display the analysis program for table &V1& by
selecting the records for table &V1& in transaction CNV_10020_DTFLD and
then running the program generation in test mode for the analysis.
