wrong message length custom user data header

[aordonez]

Hi, I'm having a problem sending multi part messages, adding custom user data header, adding ConcatenatedShortMessages8bit . At the moment of build the submit I get the correct message length
like the image bellow

But capturing the SMPP submit y see that I'm sending a wrong message length.

What I'm doing wrong?

It is not correct to use User Data Header concatenation and MessagePayload parameter. You need to use SAR TLV Parameters with MessagePayload.
