·         For PF1:

Once the report is displayed, check the values in column variance. If the amount is different to zero column this means that there is a difference between FI and MM. This check should be done for all stock accounts (check page down until the end or the report).

 In this example we have a difference in account 2000010000 of  99.331, 00 €.

• For WP1:

In this example we have a difference in account 31000100 of -84.382,01€

Go to  report S_ALR_87012332 and use the following parameters:          Select the variant 3S-FIMMCHECK; Select the account(s) that is generating the difference; The company code and execute.   Considering the previous example, the postings generating difference is from 2007: Once the posting that is generating the difference is identified, report to Company Accounting Manager (in this case there were manual corrections done in FI but not in MM, therefore generating a difference between the two modules).
