Bespoke field being cleared by Req. Worksheet

Hi,

On the “Req. Worksheet” table I have a bespoke field called “Long Description”. This is mirrored on the “Item” table and is populated by copying from the “Item” table. The issue is with “Calculate Plan” feature on “Req. Worksheet” page. When I run “Calculate Plan” all of the expected results populate the worksheet. However if the “Action Message” is set to anything other than “New” then my bespoke “Long Description” is not copied across to the “Req. Worksheet”. I am struggling to figure out why as there is no bespoke code that would cause this so the problem must lie in the standard code. Would I need to add my bespoke field to a block of code to populate the “Req. Worksheet”? I could really use some help here.

Thanks

Gav
