Help needed with EXIT_SAPLMDR1_005 for rounding

Hi Guru's,

We have an issue with the user exit EXIT_SAPLMDR1_005 in ECC6 system as it isn't being triggered.

We've recently performed an SAP upgrade from 4.7 to ECC6 and when creating a PO in the 4.7 system we've stuck a breakpoint at the customer function call and noticed the code within this exit is performed. However, when doing the same thing in ECC6 system, the code is not performed.

My understanding regarding these user exits is that a customer enhancement would exist in CMOD, however none exist in either system that calls EXIT_SAPLMDR1_005. Am I missing something? Is there a setting in config somewhere where this exit needs specifying?

Hope someone can help, thanks

Chris
