Is it possible to access the ttQuoteDtl table for calculation in custom code from - Data Directive, QuoteQty, In-Transaction, Custom Code. I’m working on a BPM to calculate a value at quote entry and need to access both ttQuoteDtl and ttQuoteQty.

This can get very tricky… data directives only have “access” to the table that they are being triggered by…so if you write a data directive on the QuoteDtl table, you cannot see QuoteQty, or QuoteHed without reading them from the “disk”.  
Typically, you have to write more complex C# code that will go to retrieve all the related data from those tables to do your calculations.
