No entry in table $ for key $ at $ T511K with custom constant

Hi HR Guru,

I need your help and opinion guys, I set up one constant in table V_T511k as a cut off date, the constant name is ZGMWA with the cut off date is 30.11.2013. When I run the time evaluation with the date after 30.11.2013, everything looks okay, however when I run it for back date before 30.11.2013 there will create an error like these :

No entry in table $ for key $ at $ T511K    13ZGMWA                ### 29.1

Technical error no. 72

29.11.2013 Processing terminated for EE XXXXX

Can you please give me some advise for the issue ?

Many thanks,

John
