The problem seems to be with the way the datasets(2000-2014) are created. the length ogf variables are set once the first dataset is appeneded to the IIOdat.WIO.
Please do the proc datset on one or 2 of the dataset and see if the length is same for these variables.

These errors are shown because of the way the output data set is getting created.
For the first time when output dataset is created from first input dataset, it sets all variable attributes (their lengths and types) from this dataset. When the same is repeated, it is not matching with the existing information that output data set has set in it's PDV.
As an alternative, you can use the LENGTH statement in the beginning for the variables being shown in the log, so that you get a fixed length for those variables in output dataset and then try.
