Help com RFC - parameter Xstring

erros-xstring.pngGood Morning.

I am creating an RFC and managed an Enterprise Service (SOAP)

The RFC should receive a parameter of type Xstring. This parameter will convert to binary (SCMS_XSTRING_TO_BINARY).

However when testing, the error of the attached image is occurring.

How can I pass an Xtring value as a parameter?

Everything we can tell you is in the error message.

Somewhere in your program you are probably trying to decode Base64 string and it fails.

The first bytes "89504E47..." in your log, correspond to the bytes of a PNG file, but they are not encoded in base64. If you define a parameter of type XString, and you create a Web service around, then SAP framework expects a Base64 string and decodes it into an Xstring. Solution: call your web service with your PNG encoded into Base64. Another solution, maybe, is to map to a different type in your service definition (tab "Types").

I would check the possibility of encoding and decoding using ABAP class CL_HTTP_UTILITY.

As suggested by Sandra Rossi I am passing as string and inside the RFC again converting to xstring, the error has been solved. Thank you all.
