Problem Note 36836: A error can occur when increasing the GENMAX value for a SAS generation data set that has rolled over
 |  |  |  |
Prior to SAS 9.4, when changing the GENMAX= option to increase the value on a SAS generation data set that has rolled over you will receive the following error message when accessing generations that were created with the previous GENMAX= value.
ERROR: the version number specified in this file generation
is out of range.
The limit for generation version numbers in SAS is 999. After 1000 replacements, SAS rolls over the youngest version number to 000.
Prior to SAS 9.4, in a situation of having a SAS generation data set that has rolled over, you should not modify the GENMAX= option with a larger value, otherwise you will recieve the error noted above. If you require a higher GENMAX= value after a SAS generation data set has rolled over, you will want to save the generation data set you have to date, then start over with a new generation data set and set the GENMAX= option to the desired maximum value.
This problem is fixed in SAS 9.4.
