1941429 - Program name is missing A1 4 message in the syslog

Similar entries appear in system log:

|Time      |SAP instance|Type|Nr |Clt |User|Transaction Code    Terminal|Priority|Grp|N|Text
|09:31:15|xxxx            |DIA |000|110|Z002T2PV   |               |xxx|     |A1 |4|> in program , line ??? , event|
|09:41:36|xxx              |DIA |000|000|SAPSYS     |               |xxx|     |A1 |4|> in program , line ??? , event|

The focus is on in program , line ??? , event, where both program and line and event information are missing.

The sequence in syslog is direct after each other:

1. A1  0 Initialization complete
2. A1  4 > in program , line ??? , event

This means:

• WP restart
• initialization
• unknown 'A1 4' entries in syslog during intitalization of SCSA

According to SM21 looking for time stamp in dev_W0 no further, relevant information are seen:

In "normal" cases the message should look like this (details of A1 4 syslog message from SM92):

> in program &4&9&9&9&9, line &4, event &2&9&9

Example:

A1  9 Field contents changed: I_KOMP-WERKS -> 0025
A1  4 > in program LWVKCU21 , line 0271, event SALES_PRICE_READ
A2  3 Goto ABAP Debugger: Source:(411)->(416)   ByteCode:perf(
A1  4 > in program LWVKCU21 , line 0416, event SALES_PRICE_READ
