Error to consume automation variable Dynamics 365 Business Central

Question

I create an automation variable in Dynamics 365 Business Central On Premise.

This code work fine the first time but then an error apear.

Code:

EVALUATE(_PC, PCStr);

CREATE(_Export, TRUE, TRUE);

_Export.process(_PC);

Answer 1

This happen because you never clean your automation variable. You have to use CLEAR() sentence.

Example:

EVALUATE(_PC, PCStr);
CLEAR(_Export);//to clean your automation
CREATE(_Export, TRUE, TRUE);
_Export.process(_PC);
