Error Logging DLL (Baan / Infor LN)


Baan handles error logging very well, you must be using ttstperrlog session frequently to verify the logged errors. In many scenarios, we need additional error logging for write/process programs. It is really time consuming to create create traditional baan reports for error logging. So most of the times we prefer writing to a log file. Many of you must have already written the dlls to write your errors to the log file.

While going through the archives, I found one of my very first program for error logging, you may use it without any restrictions & enhance the same based on your needs. I will definately like to know the changes you have done, so request you to share the modifications & enhancements done.

This is no different, the DLL uses report name as an argument and passes the error string to the report. This gives you the flexibility to save the reports in any format you want based on the availibility of the devices in your environment.

The DLL lifecycle have three stages init, log & end.

The details are as below

init.log()

The function init.log will initialise the “error log report”, The user can provide the report code or pass a empty string as a parameter to the function,  In case of empty string the default report “rXXXXXXXXXXX” will open. The user can optionally pass the Report Title in the second argument under DSNtitle.

As a first step the developer will need to change the DEFAULT_REPORT & DEFAULT_TITLE values to the desired ones. There should be one report with the field error_desc with string datatype.

The init function will initialize & open the report. The init function will return the report id which is of type long.

log.error()

The log.error() function takes two parameters report id & error details. This can be called inside a loop multiple times provided the log is initiated.
The log.error() function will pass the error details to the report. The report id, which is the first parameter for the function is the id returned by init.log() function.

end.log()

This function will end the log by closing the report.
