Fail to use MIP Start

I am currently working on a larger MIP which I'd like to speed up. In this Forum I read about using the Mipstart option (since I am using CPLEX as a solver)
However, GAMS gives me the following message in the log :" mip start 'm1' defined no solution" which confuses me because I took this solution from a pre-solve of the exact same model.

Any suggestions why GAMS does not accept the initial solution ?
How do you provide your model with initial solutions? Perhabs, I've chosen the wrong way.

Kind Regards
