Hi Tariq,
May be the issue with LMDB details, first go to sld and check SOS system having latest details.if not update detail through RZ70 and check the time stamp.
After goto solman system -> se38 -> RLMDB_SYNC_TECHNICAL_SYSTEM -> enter SOS details and check box the last option. it will delete and recreate the SOS system in solman with updated detail in SLD.
then try again.
Rg,
Karthik
