PLMWUI: Engineering record Advanced search -TREX set up

Hi Gurus

We have implemented SAP Engineering record on PLM 7.02 by creating custom case type involving both custom Z* & utilizing few SCMG* standard tables. Everything on the ER works per our requirement except "Advanced Search"; our advanced search both under "Engineering record" & 'Full text search" tab returns no results.

We have checked:

1. with basis & indexing is already running for ER

2. Checked config under PLM Web application> Define settings for PLM search > Std Object type: PLM_ECR is already set up with ESH Enterprise search

However still the PLM web UI returns no results. Kindly guide if someone knows the fix.

Thanks in Advance!
