Confirm LT12 causing inconsistency in TO update

Dear Scn's,

We are facing issue in TO update while confirming TO in LT12 transaction.. In RLQCHECK report it is showing TO is missing for some of the line items in TO. But if we confirm TO in LT24 system is updating the TO without any issue.

Using LT24 for TO confiriming is consuming more time as there will be 300 to 400 line item in TO.

So please suggest what can be done to achieve the issue.

Regards,

Shyam
