How can I copy a field information from a module to other module?
For example if I have a field information in account module, and I want to copy this information for example to invoice module.
In the other hand, how can I concatenated two text information in one field?, Is it possible using workflows? like calculated fields…?
String concat should work without any special function, just insert your two variables as needed, you can also combine them with static elements:
{P0}-myStaticString-{P1}{P2}{P3}
It works!!! Many thks
you’re welcome 
if you want to explore the other possibilities, have a look here:
I did, but I failed to copy a field information from a module to other module, using “Workflow Calculated Fields”
About concatenated using “Workflow Calculated Fields” it works well!!
