Adding Columns to the matrix in SAP B1 user form using Visual studio 2010

Hi,

Using Visual studio 2010, I have created a SAP B1 user form( b1f ) with one matrix. Matrix is having 5 columns. Its working properly. Later, I want to add few more columns. Then I added columns to the matrix as I have created columns initially. But, it does not saves.

i.e, Whenever I run, In B1 I could see only old columns. Newly created columns are not showing.So, I closed the .net project and opened again. Created columns are not showing in visual studio b1f itself. So, I created again and saved. But, its not saving.I tried it many times.

Kindly assist me.

Thanks and Regards,

Ram Sedha
