Copying Plds

Dear All,

I can not export PLDs by exporting them through Report and Layout Manager.

It gives the following error:

I have tried to copy and paste the PLD by select all, copy and paste in the required data base but it doesn't copy all the fields in the pld.

Copy express add-on is not shown in the add-on under administration module.

Urgent help needed.

Thanks in advance

Ali Naeem
