I have a little problem with my model
I'm using two stores, the parts are stored when some buffer or machines have failed. Then, when a part enters to any machine an attribute is created to move the part from the store to the correct machine when is operational again.
The problem is it appears a message with the next error: User-defined attribute was not found, I can't identify what is the problem because the attribute is created in the entrance of OP20.
I hope you canl help me, or give some suggestions for modeling this process easier.
