xFlow Trace
Notes on Parameter XF_RTTRC_FILE_SIZE
The parameter should not be set to a value of more than 4096 (KB) if the trace is to be displayed with the transaction /WMD/XF_TRACE.
The reason is that the SAPGui-Textedit-Controls is used in this transaction. The transaction is not able to process data volumes of any size. If this file is too large, an SAPGui-OLEAutomation error will occur, resulting in a short dump. If this should happen, either diminish the value or use Transaction AL11 used for display.
When using xFlow in multiple clients, set the parameter to the same value in all clients. If the parameter is set differently in different clients, the smallest value defined will win.
Notes on Parameter XF_RTTRC_LEVEL
The behavior of xFlow Trace in respect to the trace level has been slightly modified, as follows:
Level 4 is now exclusively reserved for writing the ABAP callstack.
On Level 1, notifications of the type INFO are also written.
Here is a comprehensive overview:
Trace Level | Description |
|---|---|
Level 0 or parameter does not exist or is not set. | A trace is not output. |
Level 1 | Error messages of the notification type ERROR are output. In addition, notification texts are logged which are output on Level 1 based on their relevance but are not caused by any errors, for instance, if relevance for release has not been established for a document because of customizing. |
Level 2 | In addition, warnings are output. The notification type is WARNING. |
Level 3 | In addition, messages indicating success are output. The notification type is SUCCESS. When, for instance, an order has been set up by BAPI, it is logged on this level. |
Level 4 | In addition, the ABAP callstack is written. |
Level 5 | In addition, the changes in the xFlow runtime tables are logged. The notification type is INFO. |
Level 4, and in particular Level 5, lead to the generation of larger data volumes, for which reason we do not recommend setting this level permanently.
WMD recommends setting the trace level in the productive system to 1 as WMD Support will ask for Level-1 traces in the case of error.
