data is not saved in customer field by CNEX0006

Hi Experts,

With the help of ABAP, i have implement the customer exit CNEX0006 to add addtional field in project definition. The filed is 40 character filed name ZPS0001.

I put the value in the field and save the project but the value does not shows in the field after open the project next.

I have checked the table proj, the value also does not show in the addtional field.

Could you please help how to store the value in the additional field.

BR,
