When I am executing my model builder, the error 000539 appears at the reclassification proces. which is a intermediate step in the model builder. Though the model processed 20 files successfully out of 24 files and results generated for 20 files are completely acceptable format and their are good.
Please help me trace the error in the following work flow of my model.
This looks like a data specific error where your Calculate Field expression is not working correctly based on the expression string contents. Without seeing the expression that is failing, it's hard to help you out. Are a few of your 24 rasters named differently in some way?
The expression that is failing would show up in the GP messages that print while your model is running, looking at the GP message may provide some clues.
