I have the following ST22 short-dump:
"UNCAUGHT_EXCEPTION" "CX_SY_STRUCT_COMP_NAME"
"CL_ABAP_STRUCTDESCR===========CP" or "CL_ABAP_STRUCTDESCR===========CM00E"
"CHECK_COMPONENT_TABLE"
Multiple Specification of the Name 'ACTION' as a Component Name (Component 3)
Background:
I have a Gateway service, built in SEGW, with a number of entities.
None of the syntax rules are broken in my service.
I am able to do READ, QUERY on ALL entities.
I am able to perform $expand on a number of entities, with no errors.
Issue:
On two of my $expand URL I get back an error: "RFC Error: An exception occurred that was not caught."
In the backend I see the issue details, one example is shown below:
The ABAP filed name EMPLOYEE_D is being highlighted as the issue... EMPLOYEE_D only occurs once in the model of my service:
I have not implemented any manual change in the MPC_EXT for this gateway service.
I have tried setting a breakpoint in class CL_ABAP_STRUCTDESCR method CHECK_COMPONENT_TABLE but it is never hit, even though this is where the short-dump is being triggered from...
I have attempted renaming the ABAP field name in the backend dictionary structure.. but this has no effect (or appears to have none).
I found a few posts about this before, but cannot see any answers:
Multiple Specification of the Name 'ATR_0003' as a Component Name (Component 2)
Multiple Specification of the Name 'ADDRNO' as a Component Name (Component 2)
I need to be able to perform this $expand on these entities, but cannot see a way around it....
Any advice will be rewarded 
Please help!
FYI this is my system component info, the bits which I think are relevant... like IW_BEP...
