CCR error code 168-Diff in content

Hi,

We are finding many orders with CCR error code-168 diff in content. After resending data to APO these are not getting corrected.

When checked randomly most of these orders are overdelivered. ie. delivered quantity more than order quantity. How to correct ther error?

Error description- Quantity in APO is zero while in R/3 -XXXX.

Regards,

Santosh
