Is there a way I can use a system module as my driver in the picklist ?
Apologies, I can't find any related topics on this, please share if there are any.
Thanks in advance.
Yes and no.. The picklist can only use values from list properties, so it is best to have those list properties defined but be driven (populated) by a formula referencing line items in a SYS Module.
Have you explored using a line item subset to turn the line items in your system module into a list.
You can then assign this to your pick list line item.
However, without further details regarding what you are trying to achieve it is difficult to elaborate.
I will need to use the system module as i need to depend my dropdown based on the combination of two list.
