Hi,
I had missed on mapping the ET_RETURN and so in the second or subsequent calls it is throwing some error messages even though everything is the same. I will look into the ECC side now. Some custom coding is done at ECC side. Due to this missing ET_RETURN mapping I was thinking that it was not calling the RFC again. Sorry for the confusion.
Thanks for all your suggestions and quick responses. Appreciate it.
Best Regards,
Anand Patil
