Problems reading SRM Guid throught PI proxy interface

Question

Hi all,
I'm facing the following problem: I have to adapt an existing PI interface between SRM4.7 and a legacy system to the new environment in which there is a SRM7.01 and the same legacy system.
I need also to have the two configurations working together for a certain period.
The communication between PI and SRM is proxy (for SRM4.7 either for SRM7.01).
On PI side has been defined a custom outbound interface MT_Rda_From_Srm with Rda fields, where the field GUID is of type base64Binary.
Unfortunately the behavior of the field GUID is different in the two environments: this field is filled different when the abap proxies pass the RDA GUID. I think this is due to the fact that in SRM4.7 the GUID of the EXECUTE_SYNCHRONOUS method of the outbound interface is treated as string while in SRM7.01 the GUID is treated as rawstring.
Debugging abap custom code the value of the GUID appears as a string, while if I look the message in SXMB_MONI the Guid is string in SRM4.7 and it has a value like  
<GUID>TKo6ZBHYAVDhAIAAChAZZg==</GUID> in SRM7.01.
So, when I have to pass this value to the legacy system, it does not correspond to the real value of Rda GUID.
I would like to not change the PI mapping to differentiate the behaviour according to the SRM that sends the Rda data...does anyone know if there is a standard way to work with this kind of data?
thanks for your help,
Luciana Agostini

Hi,
tnx 4d reply...
SRM 7.0 contains 2 clients:
Sender: 100 for EBP, logical system is CLNT100
Receiver: 200 for SUS, logical system is CLNT200
both the clients are connected through PI 7.0, logical system of PI is CLNT001.
From SPROXY of 100EBP, i'm executing the outbound proxy, in moni sent msg success.
In PI also msg is processed.
As U asked me to chk... SPRO settings in "Define Backend Systems"..... in which client i've to chk this... & what values needs to be maintained der.... can u pls tell me....
SPRO->SRM->SRM Server->Technical Basis Settings-> Settings for Supplier Synch--> Define Settings for each backend system.
click help icon... in that " Define Backend Systems "
the following data is maintained in 200:
Logical System: CLNT100
Dexcriptn: Local EBP
RFC Destination: CLNT100
System type: EBP_ONE
RFC: tick checked
Local: tick not checked
FI valid: real-time backend validation
Logical System: CLNT200
Dexcriptn: Local SUS
RFC Destination: CLNT200
System type: SUS_ONE
RFC: tick not checked
Local: tick checked
FI valid: real-time backend validation
& in SPRO->SRM->SRM Server->Technical Basis Settings-> Settings for Supplier Synch--> Define Settings for each backend system.
execute
nothing is maintained.
In which client what needs to maintain pls tell me...
& also what is the value to give in SLD System name field.
Pls help in resolving the same....
tnx n rgds,
