Hi Ana,
As mentioned in your previous post, you can create a new static entity called GenericField with attributes label (Face photo and Body Photo )and Filter code (Face photo =1 , body photo=2) which defines the images in your main entity,
Add foreign key of static entity into main entity and add input parameter to the upload doc module of filer code.
The data type of the input parameter will same as the data type of Filter code (Attribute of GenericField entity) in my case i have used text the filet code is in numerical format. Like for face Photo 1 and for body photo 2
Please do not create duplicate post,
Regards
Komal
