Error parameter in view

Hi,

I have 2 methods in my WD.

The first one I have called CHECK_DATA and it contains an export parameter named ERROR of the datatype CHAR1.

This method is called within my method = CREATE_REC.

In this method I also have a parameter called error = char1. When I call CHECK_DATA I use the IMPORTING error and fill the error parameter in CREATE_REC.

It compiles, but when I run it, I get an error 500 that tells me that the error parameter contains an invalid value.

Why do I get an invalid value for error parameter ?
