External number range for SUSPO in SUS-MM

Question

Hello there,
I'm running ECC 6.0 with SUS-MM 5.0 (SRM server 5.5). When transferring ECC purchase orders from ECC 6.0 to SUS-MM the resulting SUSPO is created using internal number assignment.
Thus I'm having an ECC purchase order 45xxxxxxxx referring to a SUSPO 30xxxxxxxx.
I do have an external number range of 45xxxxxxxx in SUS-MM.
Any suggestions/comments very much appreciated.
Cheers,
Franz

Hi ,
This is what i got from HELP
>
Define Number Ranges for Purchase Orders
Use
In this IMG activity, you specify the number ranges for purchase orders in SAP Supplier Self-Services (SAP SUS).
Only carry out this IMG activity if you create purchase orders locally in SAP SUS.
Activities
1. Choose Changes Intervals -> Insert Interval.
2. Specify at least one number range.
Note that you must enter the number ranges specified here when you edit the transaction types. For more information, see
Vorgangsarten festlegen.
3. If you set the External indicator, suppliers can enter their own numbers in SAP SUS. If  you do not set the indicator, the system generates numbers automatically  (internal number assignment).
Further notes
To export number range objects,  go to the Maintain Number Ranges screen and choose Interval -> Transport.
Note that,  before the target system imports the number range objects from the source system it deletes all of the intervals for the selected number range objects. This means that after the import, the target system only contain intervals that were exported from the source system.
You cannot transport or convert dependent tables.

so according to this , it should be possible to have external number , please check wether you have maintained customizing for SUS purchase order numbers at correct place.
