Hello,

try one of these, i.g. query.extend.where.

Query extensions 
--------------------------------------------------------------------------------
Query extensions define conditions that the 4GL engine adds to the SELECT, FROM, and/or WHERE clauses of a database query in order to minimize the number of fields read from the main table and in order to retrieve all reference table fields required by the UI and/or DAL scripts. 

BaanERP provides the following functions for constructing query extensions: 

query.extend.select() 
query.extend.select.from.in.zoom() 
query.extend.from() 
query.extend.from.in.zoom() 
query.extend.where() 
query.extend.where.in.zoom() 
You can program query extensions in the UI script and/or the DAL script. In the UI script, you program the extensions in the before.program or before.zoom sections. In the DAL script, you program the extensions in the before.open.object.set() hook. 

For a full discussion of query extensions, see SQL Query extensions.

Example:

query.extend.where(" (tisfc001.osta = tcosta.in.prod or tisfc001.osta = tcosta.active)", EXTEND_APPEND)
