Add empty data in a trend

[DannyB]

Hi everyone,

I have a trend "nb_share". I create a copy of this trend like this "copy nb_share nb_share_forecast".

I want to add 48 empty values at the end of the forecast serie. How can i do that?

Regards.

Are those observations in the workfile? (I.e. Does the workfile range cover those 48 observations?$

When i import my file i have 508 values in the main series (nb_share). but i want to add 48 empty values at the end of a copy of the main series
