Log File (SAP Library - Loader: SAP DB 7.4)

Log File

During the start of the SAP DB Loader, a log file is created or updated. The name of this log file is loader.prt. The file is stored in the run directory (…\wrk) of the database instance.

The following information is logged in the log file:

Database name and user name
Start and end of a load or unload action
All executed SQL statements
All executed load commands
– For each load command, the position of the rejected input records in the medium and the cause of error
- For each load command, the accumulated counts (inserted/modified lines and rejected lines)
All executed unload commands
For each DATAEXTRACT command, the accumulated counts (number of extracted lines, and the number of lines extracted with errors)
A message if the action was terminated

The log file is structured in such a way that parts of it can be easily used to create a command file.

All comments begin in a new record with // * or // <letter> and are ignored by the SAP DB Loader.

Special comment lines:

// M	Line with messages These are informative system messages, such as the number of lines inserted and rejected, last completed transaction, and so on.
// E	Line with error messages This is used to introduce the two lines with the table and position values as well as the error number or error text for rejected lines.
// R	Line with REMARK comment These are comments that the user specified using the REMARK command.
