This registry entry changes the default PC-DMIS schema to save the hyper report. A value of 3088 is the first PC-DMIS schema to account for the CMM setup in a hyper viewset. A value of 0 (default) causes the hyper report to save in the same schema as it was read in, as long as it is not higher than the current PC-DMIS schema, and it is higher than 526 (a really old version).
A very large schema value causes PC-DMIS to use the current PC-DMIS schema. So, if you want your hyper report to use the current PC-DMIS schema, use 1000000 or some other similar large value. However, be aware that if you're using a development version of PC-DMIS, it may have a higher schema than a release version. If you then switch to the release version, this may result in a saved hyper report using a PC-DMIS schema that your release version cannot understand.
If you wish to update hyper report to the schema they defined, each hyper report needs to be opened/closed for this to happen. This could be done during normal execute or by pressing F9 on the command or by selecting File | Reporting | Edit Legacy. The file simply needs to be opened/closed for this to happen. You only need to do this once. Once the hyper report is using that PC-DMIS format, it cannot be opened by any PC-DMIS version below the user defined schema. If anyone attempts to do so, PC-DMIS may crash since hyper reports were never backwards compatible.
Entry Name: HyperReportPcdmisSchema
Entry Type: Integer/long value specifying the PC-DMIS schema to use when saving hyper reports. The default value is 0. You should avoid the following schema numbers since the CMM setup is not supported in them:
< 3087
>= 3250 but < 3284
>= 3600 but < 3639
>= 3800 but < 3805
>= 4000 but < 4004
Hyper reports default to PC-DMIS schema 1223 (v37).
