 Hello Experts,

I am trying to promote the fields inside the repeating table. So I created a text box to hold all the values inserted in the repeating table and then finally promoting the text box created.So I used the below formula

eval(eval(group2, 'concat(my:prodDocumentMaetial, ",")')

The issue was having extra ","

So I changed the formula to

substring(eval(eval(group2, 'concat(my:prodDocumentMaetial, ",")'), ".."), 0, string-length(eval(eval(group2, 'concat(my:prodDocumentMaetial, ",")'), "..")) - 1)

Now the issue is it is not displaying the last entered values properly.

 Hi, how about having formula such as:

    substring-after(eval(eval(group2, 'concat(",", my:prodDocumentMaetial)'), ".."), ",") 

 This formula creates   ,item1,item2,item3 (comma first, and then item), and then takes substring after the first ','
