VBOF does not update agreement with invoices

Hello,

We have a problem with some agreements that have been change during the validity period. There are some invoices that are not included for the agreement. When we run VBOF we get the error message "No correction due to value change" and the agreement is not updated. I have no checks in Test.

When I go to transaction VBO2 I get the message "The sales volume for agreement 24525 is not current".

I can find the entry in VBOX, but not in structure S136. S136 is set to Syncronous update in transaction OMO1.

I have also run transaction OVB3 for one of the invoices missing. Is there anything else I can do?

We did an upgrade from 4.6 to ECC 6.0 in March. Can this have anything to do with the problem?

Best Regards

Ann-Sofie
