Last week we’ve encountered some strange behavior (read: short dumps) in our BW system. For some strange reason the user exit for variables (function module EXIT_SAPLRRS0_001; include zxrsru01) was generating shortdumps. Analysis revealed that there’s a maximum of 32kb of compiled code which the abap runtime environment can handle. (This limitation is not regarding the number of coded lines, but the amount of byte code generated)
This limitation was breached as we’ve placed all our user-exit code in one big CASE/ENDCASE statement.
When we replaced this big CASE/ENDCASE statement by several smaller CASE/ENDCASE chunks, everything worked fine again.
Thanks to Crispian for the analysis
