In a discovery rule I check for the SNMP items sysLocation.0 and some OID that describes the type of the device (ceAssetOrderablePartNumber.1).

I want to use both, sysLocation and the AssetOID to check if a found a correct device for the group I am looking for.

Checking ONLY for the correct value of sysLocation.0 in "received value" of the action works.
Checking ONLY for the correct value of ceAssetOrderablePartNumer.1 in "received value" of the action works.

Checking for BOTH in "received value" will not detect devices.
