Specific middlweare

Hi,

The data are transfered from CRM to an external system by specific Middlweare. XML files are generated in the external system after each run.

The execution takes longer for Initial Load.

I wanted to know what takes more time: recovery of data to send, Call the external system (RFC), generation of XML files, other?

Has anyone experienced this problem ? any idea? tracks?

Thank you in advance,

Best regards,

Mat
