SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20200_CHECK - Messages for check functions (company code merge)

• Message number: 179

• Message text: Difference of tax postings between company codes detected

What causes this issue?

At least one company code has differences regarding the tax postings in
the last balance sheet adjustment run. This means that for at least one
company code, the postings for the balance sheet adjustment also
included taxes, but not for all participating company codes. This has no
effect on your actual tax payment but on the internal tax distribution.
If you want to use the tax postings for the merged company code you have
to run the next balance sheet adjustment with tax postings. Note that in
this case all tax postings of previous runs which are not yet considered
are booked in the next period.
