About Adding Filters
Using the By Rule command on the FILTER TYPE menu, you can remove multiple items that match a specified pattern. You can use filters in the following forms to further specify the information you want displayed:
• <symbol>—Any parameter that is valid in a repeat region
• <comparison operator>—Any of the operators <, >, <=, =>, ==, and !=
• <literal value>—Any integer, floating point, or string value
Filters exclude from a repeat region any record that uses one of the filtered parameters and whose value does not match the constraint defined by the filter. The system omits the entire record from the table, and not just the parameter affected by the filter. For instance, the filter &asm.mbr.type==part in a repeat region omits all records of objects other than parts from the report.

If you filter in a two-directional repeat region, it only removes the particular cell, not the entire record.

A filter such as &asm.mbr.material!=steel excludes all records of assembly members with a material parameter value (user-defined) of "steel" from the report.
You can also enter filters that work for multiple values, such as &asm.mbr.name==part_a,part_b,part_j, which would exclude from the report all records of assembly members other than "part_a.prt," "part_b.prt," and "part_j.prt." A line that defines a filter can contain up to 80 characters. When creating a filter with multiple acceptable values such as &asm.mbr.name==part_a,part_b,part_j, you can only use the operators "==" and "!=".
When using filters with "==" and "!=" operators in a repeat region, keep in mind the following points:
• If you add filters with the operator "==" to more than one line in a repeat region, all entries are blanked and the table appears to be empty.
• For "==" operators with more than one value, the values are linked by "or." For example, for the filter &asm.mbr.name==part_1,part_2,part_3, the repeat region excludes all objects other than those parts having the name "part_1," "part_2," or "part_3."
• For "!=" operators with more than one value, the values are linked by "and." For example, for the filter &asm.mbr.name!=part_a,part_b,part_c, the repeat region excludes those parts having the name "part_a," "part_b," and "part_c."
Use the commands of the FILTER REG submenu to add, edit, or clear filter statements associated with a repeat region.
You can use the Filters command for records that represent flexible components, Family Table generic components, bulk items, and included items within a repeat region.
