Document is getting saved, but not updating in the data base

Hi,

We are getting an issue at the time of GRN and Invoice

While saving the GRN document(MB0A) or Invoice, system is generating the successful message of posting the GRN document or Invoice.

But when we are going to check the GRN no in MB02/3 or Invoice no in VF02/3, we are getting message as"No document exist".

Neithor GRN has been posted nor stock moment has been done every time.(Same case with Invoice)

Kindly suggest.

Thanks & Regards

Ritesh Kumar
