Upload Server SAP Excel to SAP

Hi gurus,

I have an Excel file into Server SAP, specifically in /excels/test.xls. In transaction AL11 I can see the excel. Besides of this, I programmed a function that upload the excel in an internal sap table. I use 'TEXT_CONVERT_XLS_TO_SAP' and it is necessary run in background. If I run function in SAP Bussines Connector I receive and error CNTL_ERROR. If I run function with SAP GUI I receive a message file not exists or it can't be managed and, finally, If I choose an excel from my laptop, from my desktop the functions runs OK.

I don't understand what happens, I thought it was easier jejeje!

Thank you a lot!

I will revvard answers!
