Accounting with SAP R/3
A system object whose purpose it is to ensure that you revaluate your assets at the correct intervals.
You define the posting variant in Customizing; when you run the Asset Revaluation (Inflation) program, the system will only allow you to execute an update run for the dates that you have specified in the posting variant.
Assume you have to revaluate your assets at the end of every month. In that case, you would use a posting variant with the dates 31 January, 28 February, 31 March, and so on.
