Issue in FB70 BDC

Hello Experts,

I have come across a unique issue :

I have created a BDC for customer invoice posting (TCODE : FB70).

The BDC is working fine if i use my ID to upload the excel sheet and execute the program ;

The entries are being posted;

But when the user tries to post entries via his ID the program displays an error message :

" NO batch input data for screen in SAPLACHD 1000 . "

Me and my client have the same roles and authorizations but still this error message is being displayed.

Kindly help.
