Error Invalid sapgui input data: invalid EOKDUMMY_1 header length

Hi!

When using a transaction via SAPconsole I had the following message:

Invalid sapgui input data: invalid EOKDUMMY_1 header length Press any key...

That only happens when I execute the transaction via a device "data collector" and do not happens using SAPgui on my computer.

It happens when I fill fhe field LEITURA with any information. Even with a single number or letter.

Maybe the field LEITURA there are too much information to put in.

When I use the SAPgui on my computer, it works pretty fine:

I appreciate any help!

Thanks!
