Thanks for your reply Christian,
So I visited the link you pointed out, and now I configured a new message listener, of type XMIISRFC. I did it cause this kind of message listener let me choose input and output parameters when I choose to execute a transaction in message processing rules.
On MII side I had already figured it out, and I can access the input of XML, that is also the exporting parameters of the function that I called in ABAP with MII as destination (everything ok so far). The bls transaction is executed on MII and I get the XML I chose as the output of the transaction. The trouble comes when I try to get the values of this output into abap, i.e. into the importing parameters.
Do I have to link the output XML of bls transaction with the importing parameters of the function I called on ABAP side in any other way, or do I have to transform the XML into a character type recognized by ABAP? Or anything else...?
Thanks.
