Repeated measurements in R structure

Dear group,
I’m struggling with the analysis stated below. Any help would be highly appreciated.
Many thanks in advance for your time, and sorry for my limited knowledge of ASReml

Analysis goal
I have 107 genotypes (Gen) measured (for Yield) at 3 different time points -1,2,3, equally spaced- (Time) with 3 replicates at each Gen/time combination. Another variable in my dataset is location (LOC with 5 levels), plus others not participating in the analysis P7,X,XM,Xmn,PT
I want carry out a ‘repeated measurement’ analysis as if it was a ‘spatial analysis in one dimension’, this means, specify different correlation/covariances between time points across genotypes in the R matrix and not in G. Is it possible? I have problems, according to the asr error message, to sort data into field order. Please let me know if I’m out of track on the following:
