Filtered intial load / request from more than one backend
on a SRM 3.0 system I am trying to download regions via CRM Middleware from two different backends.
For this purpose I chose Customizing Object DNL_CUST_BASIS5 in TC R3AC3 and deactivated all tables except for T005S and T005U.
Then I downloaded the regions from the first backend.
From the second backend I just wanted to add the regions of country CZ. So I tried to filter on field LAND1 (both tables).
But after the download all former entries were deleted only the new ones for country CZ were present in the tables.
This happened no matter if I maintained the filter in R3AC3 and tried an initial load via R3AS, or if I just tried a request load via R3AR2, R3AR4 using the filter.
Shouldn't at least the request load just add new entries without deleting the existing ones?
How can I mix entries from two different backends?
Thanks in advance for your answers!
