Hi Marco,
Thank you for your reply.
The BC is version W1 14.1 on-premise, not Saas. The users cannot use Saas.
I don't test it in CRONUS company. I will test it in CRONUS.
The way I produced this behavior is:
Copying the data from Excel and then pasting the data and deleted it, repeatedly.
It is like finding something wrong in the data, then deleted it, created the new/revised data, copied it, and pasted it to the Lines in Sales Credit Memo.
Thank you
