ME47-InforRecord of someitems can't update

Dear Gurus,

I am dealing with my RFQ.

I maintain 4 items for my Quotation in ME47.I go to the Condition Maintenance screen to input the future Gross Price, then set InfoUpdate indicator as C- Update without plant (if no plant requirement) for each item and hit save.

However, only the price of Item 10 is updated to the Information Record(ME13) successfully, other items fail.

This phenomenon sometimes occurs in our daily RFQ business on our PRD. We search the note ,such as 569885,but we still can’t find the reason.

Hope someone could give me a hand to solve it.

Thanks so much!
