Flow 6.15 and the earliest versions offer a possibility to choose a type of property which is either text or table. The latter ensures that more data can be stored under one property.
Infor M3 Labs uses that funcitonality to store a dynamic data that affects the way how each and every workflow behaves, ie. the prompt proposals, buttons and input fields, automation of user steps are just a few to mention.
In other words, the end-users, who more often than not are function-oriented, can utlize the table to adjust the values in the table.
By that, workflows can be 'configured' according to one's wish and benefit, without necessarly editing the flow in the studio. On top of that, any alternative solution would require storing bigger amount of data outside of the Flow Server, which most likely would be extra charged.
It would be great and of a big benefit if a similar function, that is a variable type - table, is available for Variables which will replace Properties.
