valuation of material in valuation area inconsistent but allow transaction

Dear Gurus,

I got an error c+048 and all of my transaction of the materials are blocked.

Already contact the SAP Support and materials with inconsistent error have been fixed.

But then after i try to posted one transaction, I check the CKMC and found that the materials back to status inconsistent but is not blocked.

So I can post another transaction without being blocked.

Is this normal?  And how to repair this error?

What happen if i ignore the CKMC and continue to post and process with these materials?

Does it will make my ledger data error?

Thanks in advance
