Have you maintained entry in TMCEXACT table?
You should add this entry, using se11 with create permission.
The entry should be something like:
ESTRUC ISOURCE ISGEN UPDACT ADDHEADER MCAPPUPDA
MC02M_0SRV 2LIS_02_SRV X X 02
T
MCEXACT : LO Data Extraction: Activate Data Sources/Update
Same thing is maintained in the OSS note as well.
Also check whether data is available in source table of this data-source in R3.
Thanks,
