Description:
How come when I am in a z39.50 base in web OPAC I can not access web sites via the 856 external link? I find a record which has an 856 field, but then when I click the 856 field I get "error: not found".

Resolution:
Do as follows:
Replace current 856 line in $ext01_dev/ext01/tab/edit_doc_999.eng with this line:

## 856## D LElectronic Location Y M E W

Then, backup in ext01 the file $data_tab/edit_field.eng and $data_tab/tab_service and then copy them from usm01.
Also copy the files tab_buf_z403 and tab_type_config.eng from $data_tab of usm01 to data_tab of ext01.
It can be done as follows:

cp -p $ext01_dev/ext01/tab/edit_field.eng $ext01_dev/ext01/tab/edit_field.eng.orig
cp -p $usm01_dev/usm01/tab/edit_field.eng $ext01_dev/ext01/tab/
cp -p $usm01_dev/usm01/tab/tab_buf_z403 $ext01_dev/ext01/tab/
cp -p $ext01_dev/ext01/tab/tab_service $ext01_dev/ext01/tab/tab_service.orig
cp -p $usm01_dev/usm01/tab/tab_service $ext01_dev/ext01/tab/
cp -p $usm01_dev/usm01/tab/tab_type_config.eng $ext01_dev/ext01/tab/

You should also add the following two lines to ext01 $data_tab/tab_expand

WEB-FULL expand_doc_bib_loc_disp
WEB-FULL expand_doc_type tab_type_config
