If you have a period: 201x12 for example that needs to be re-opened, or a period: 201x13 that should have status 4, the following should be performed:

1.Period 201x12 needs to be registered as the last closed period:==> Enter PAR/201x12 and choose <Set this period to closed period>.This will put PAR/201x13 in status 4, PAR/201x12 will remain in status 9.

2. Now it will be possible to open the period 201x12 by using: <Open this period> in PAR/201x12.==> It is not possible to open a period that is earlier than the ‘Closed Period’.That is why this option is not available <Open this period> in PAR/201x12 before it is registered to ‘Closed Period’
