Hello. I am administering a CRM 4.0 system. I have a custom entity containing a number of fields including three lookup fields (which point to three other custom entities). I wanted to filter the values of one of the lookup fields based on the values that have been entered in the other two lookup fields.
For example, if Lookup A contains [Employee1, Developer, USA], [Employee2, Programmer, India], [Employee3, Developer, USA] and a user selects 'USA' from Lookup B and selects 'Developer' from Lookup C, then Lookup A should be automatically filtered to contain: [Employee1, Developer, USA] and [Employee3, Developer, USA]. How can this be done?
