Changing Product posting groups with un-posted purchase invoices

Dear all 

Recently , we changed all our product and inventory posting groups( and posting setup as well) , after that we have many purchase invoices entered and posted without any problems,

Suddenly , the following error message appeared: 

this missing posting setup is the old one, I looked in Purchase line table and Purchase header table , review posting setup , theses values are nor exciting anywhere , 

any ideas about this enigma??

thanks in advance
