ABAP SYNTAX-TRACE Statement syntax, information and example SAP source code
SYNTAX-TRACE
ABAP Syntax SYNTAX-TRACE { {ON [...]} | OFF }.
ABAP_VARIANTS:
1 SYNTAX-TRACE ON.
2 SYNTAX-TRACE ON OPTION CODING.
3 SYNTAX-TRACE ON OPTION CLASS.
4 SYNTAX-TRACE ON OPTION CLASS-CODING.
5 SYNTAX-TRACE ON OPTION EXPAND.
6 SYNTAX-TRACE ON OPTION SYNCPOINTS.
7 SYNTAX-TRACE OFF.
ABAP_VARIANT_1 SYNTAX-TRACE ON.
What does it do? This statement has no effect at runtime except to switch on the syntax check or the generation of the program it specifies. If the syntax check or generation was called in the test environment, this statement switches on a syntax trace.
ABAP_VARIANT_2 SYNTAX-TRACE ON OPTION CODING.
What does it do? This statement has the same effect as
, except that the trace output is restricted to the processed program lines.
ABAP_VARIANT_3 SYNTAX-TRACE ON OPTION CLASS.
What does it do? This statement has the same effect as
. Additionally, all operations are traced that are relevant for loading classes.
ABAP_VARIANT_4 SYNTAX-TRACE ON OPTION CLASS-CODING.
What does it do? This statement has the same effect as
, except that the trace output is restricted to the processed program lines. Additionally, as for addition 3, all operations are traced that are relevant for loading classes.
ABAP_VARIANT_5 SYNTAX-TRACE ON OPTION EXPAND.
What does it do? This statement currently has no effects.
ABAP_VARIANT_6 SYNTAX-TRACE ON OPTION SYNCPOINTS.
What does it do? This statement can be used to activate the trace function of the ABAP syntax check and to select a certain mode for the trace output.
This trace mode SYNCPOINTS (for internal test purposes only) logs thedeclaration units (that is, used global class and interface declarations as well as type groups ) for which the routines for creating the load table entries must be called after a delay and not immediately.
In doing so, the call of the generation routine is delayed until a synchronization point is reached, for which the generation of a quantity of declaration units is executed afterwards.
The trace that operates on the ABAP coding level and not on the
RSYN level, provides the information, where such synchronization points were defined and which declaration units at these points in time have to go to the delayed generation.
Latest notes: The delayed generation of declaration units is neccessary to solve sequencing problems in the load tables when
ABAP_VARIANT_7 SYNTAX-TRACE OFF.
What does it do? Switches off the syntax trace switched on with
SYNTAX-TRACE ON .
