Annoying error in Proc Optmodel. Please help

Hello,

I am getting the following error during run and do not understand what is the source of the error. I have my keys of the tables matching with my tuple structure. Please help. I have attached error screenshot and table structure that feeds the tuple.

"The implied subscript count does not match with match array "Units", 3 NE 4

Following is my tuple

set<str, str, str> PickUpNode;

num PUunits {PickUpNode};

set<str, str, str> DropOffNode;

num Revenue {DropOffNode};

num DUunits {DropOffNode};

read data ex1.PUN into PickUpNode=[I VehicleID VehicleSize] Units;

read data ex1.DUN into DropOffNode=[J VehicleID VehicleSize] revenue Units;

I will appreciate your help,

Thanks,

BG

Re: Annoying error in Proc Optmodel. Please help

Seems like you must have declared a numeric parameter Units indexed over 4-tuples somewhere else.

I think you probably just need to modify your READ DATA statements as follows, because your OPTMODEL parameter names are not the same as your data set variable names:

read data ex1.PUN into PickUpNode=[I VehicleID VehicleSize] PUunits=Units;

read data ex1.DUN into DropOffNode=[J VehicleID VehicleSize] revenue DUunits=Units;
