standard deviaation field

Dear Expert ,

I want to use formula for calculating T distribution in maintenance task list for calibration plan. But in that

I am not able to use standard deviation field in that. For this I am trying to define parameter in customization

but I do not found corresponding field name and table name in database.

I want to use field standard deviation which we can see under further detail tab of inspection lot.

Please suggest .

      Dear Experts ,

      I think this standard deviation value is not store in any table. it we can found only in structure. so now what I did I creating a Z table through BADI and in that I am storing values.

      But now if I create a parameter in IMG with this new Z table and field name, and using this field in formula .

      then my value is not getting calculated in RR.

      In Attribute field I found message INVALID.

      Where I can find the significance of this invalid.??

      Please suggest
