abap-fm-logger

A logger for function module (RFC)

Let's work with function modules like IDoc.

ABAP Version: 740 or higher

Design Goals

• Save FM logs in a single general table.
• Store parameters in JSON format.
• Enable reprocessing of records using log id, akin to WE19.
• Search logs by FM & field value, akin to WE10.

Log Report

The report ZAFL_VIEWER empowers you to search logs and reprocess specific records.

How to Use

1, Add the include file ZAFL_MACROS which contains core function of the logger.

FUNCTION-POOL zzxxxx.
INCLUDE zafl_macros.

2, Call the macros on demand in the function.

FUNCTION z_fm.
  
**initialize logger. It should be always on the top of the FUNCTION.
  /afl/log_init.

**optional, you can specify at most 3 fields for search.
  /afl/set_custom_fields '2020' '1001' '2000000001'. 

**optional, you can save a status code and message text for search.
  /afl/set_status 'S' 'message'.

**save logs. It should be always on the bottom of the FUNCTION.
  /afl/save.

ENDFUNCTION.

Configuration

Table ZAFL_CONFIG allows for basic configuration.

Basic Settings

• FNAME: Name of Function Module
• ENABLED: If checked, log function will be enabled.
• EXPORT: If checked, logs for export parameters will be enabled.
• IMPORT: If checked, logs for import parameters will be enabled.
• TABLE_IN: If checked, logs for tables parameters (at the start of the FM) will be enabled.
• TABLE_OUT: If checked, logs for tables parameters (at the end of the FM) will be enabled.
• CHANGE: If checked, logs for changing parameters (both in and out) will be enabled.

Additional Settings

• NO_COMMIT: If checked, the COMMIT statement in /afl/save will be bypassed.
• NO_AUTH_CHECK: If checked, the authority check statement in the reprocess method will be bypassed.

Log Cleaner

Schedule the report ZAFL_HISTORY_CLEANER as a job to delete history log.
