You can now disallow backposting in one of two ways:
– Either cancel the Allow posting to previous per. indicator. However, this indicator is set again automatically during period closing so as to reallow backposting after each change of period.
– Or set the Disallow backposting generally indicator. If this indicator is set, backposting continues to be disallowed, even after a change of period.
