A good example of what i'm trying to do is the Journal lines/price discount agreement form under sales and marketing module. Under the overview tab, there is account code and account selection. I'm trying it to set it so that new will link account selection my new form/table drop-down. I apologize for this lengthy description. Please let me know if more clarification is needed.
I've a table with AccountRelation field(extends to PriceDiscAccountCode) and AccountRelation field(extends to PriceDiscAccountRelation). If the Accountcode selection is "table" then it will show customer name and account drop-down in account selection field. However, if the Accoundcode selection is a "group" then I need account selection to show a new drop-down(custom table). I've tried creating a table relation of type normal to new field from the new table... but this doesn't pull in the cust/vent table relation. Any tips on how I can get this to work without writing systablelookup code? I'm trying to use table relation to create drop-down.
