Statistical value transferred from ECC to SAP GTS with a different value in export declaration

Hello GTS Experts,

I am just new in the field of SAP GTS and I have request from our customer that the statistical value transferred from feeder system to GTS with a slight difference " photos attached" photo-1.jpgphoto-2.jpg.

They need to know why the statistical value is not taken from condition type and transferred to GTS with a slight different value .

Hope anyone could give me a clue how we can trigger this issue.

Thanks

Samer
