How can I correct it to show only one decimal place, for example: 7.1 kg?

What kind of parameter is MASA? Maybe you can try using MASA=MP_MASS(""), assuming the output should be a string? I'd also recommend putting this relation in post regen to avoid the double regeneration after switching materials.

If the RHS (right hand side) of the equation is a double you have to make sure that the LHS has the same type, you can have a miss match if the parameter exist before you have used this one in a relation. Just comment the relation, delete the MASA parameter and finally get rid of the comment.

Hi,

use following relation.

masa=rtos(PRO_MP_MASS)

 

rtos ... real number to string conversion
