Heterogeneous MultiProviders

Question

Hello Folks,
I've created a Multiprovider based on 2 ODS. The structure is more or less like :
ODS 1
Keys : 0doc_number + 0s_ord_item
Data Fields : Z_DTREMINI + Z_DTREMFIN
ODS 2:
Keys: 0doc_number + 0s_ord_item
Data Fields : Z_DTREMINI (I do not have Z_DTREMFIN in this ODS)
I've made up all relationships at the Identification TAB for the multiprovider. I've set up Z_DTREMFIN to be mapped from ODS1 but whenever I run my query, Z_DTREMFIN is showing like "not assigned" although I am sure its content is filled up at the ODS1. What am I missing?
This is happening to all data fields which does not exist in both ODS although they've been mapped.
As far as I understand, it should work.
The Multiprovider should have the structure such as:
0doc_number
0s_ord_item
Z_DTREMINI
Z_DTREMFIN
Any help would be highly appreciated. Thanks in advance!

Mapping of MultiProviders:
Let's take you have the following ODS contents:
ODS1:
0DOC_NUMBER 0ITEM Z_DTREMFIN
00000000001 00010 FIN1
00000000002 00010 FIN2
ODS2:
0DOC_NUMBER 0ITEM Z_DTREMFIN(does not exist)
00000000001 00010 <N/A>
00000000002 00010 <N/A>
In your MPROV you get the following records
0DOC_NUMBER 0ITEM Z_DTREMFIN
00000000001 00010 FIN1
00000000002 00010 FIN2
00000000001 00010 #
00000000002 00010 #
and since you have multi dimensional reporting these values are not aggregated. Especially is the field Z_DTREMFIN not filled from ODS1 because the key/data definition doesn't apply to the multiprovider.
Solutions:
1. Model Z_DTREMFIN as nsvigational attribute to 0S_ORD_ITEM (compounded to 0DOC_NUMBER)
2. Fill Z_DTREMFIN with a virtual characteristic exit.
3. Create an InfoSet and put this InfoSet into the MultiProvider.
