Filter Criteria

• The fields with a blank value are inactive. Thus to deactivate a filter, remove any value and/or assign its drop down value to *blank.
• The wildcard to use with the Like operator is *.
  
  For example if filter Name is like DEM, the Impact Analysis would produce all the fields starting with DEM.

• The operators Equal to, Greater than, Less than, Less than or equal to, Greater than or equal to treat * as a character and the value strictly equal for all filters except Text Search.
  
  For example if filter Name is equal to MYTEXT, the Impact Analysis would only produce the object called MYTEXT. If filter name Description is equal to My Test Field *, the Impact Analysis would only return the object with a description exactly the same as My Test Field *, otherwise nothing is returned.

• The operator Equal to for filter Text Search will remove all objects which do not contain the value specified.
  
  For example if filter Text Search is equal to Define for the Form Object Type, the Impact Analysis will return all the forms in which RDML code lines contain Define.

• The logical relationship between filters is a logical AND.
  
  For example, as shown below, if the Filters Name is STD* and the Description is Standard*, the Impact Analysis List will include all the fields and tables with the name starting with STD, and with a Description starting with Standard*.
  
  
  
  

The exception to these rules is the Text Search filter which will return all objects containing any lines of source code with the search value.  

• For the object type Multilingual Variables:
  
  Filter Text Search will search in every Multilingual Variable
  Filter Name will filter the search by Multilingual Variable Name
  Filter Description will filter the search by looking in the Multilingual Variable description, but only in the current language.

• For the object type Message:
  
  Filter Text Search will search for message in every language,
  Filter Name will filter the search by Message ID
  Filter Description will search in the message text, but only in the current language.

• The Virtual Filter in Tables searches for all tables which have a:
  
  Virtual column and this Virtual column is equal to the one specified in the filter when operator is Equal To.
  Virtual column and this Virtual column is not equal to the one specified in the filter when operator is Not Equal To
