How To Fix CNV_MBT_SHELL074 - Template switch rejected; return to the previous selection

CNV_MBT_SHELL074 - Overview

• Message type: E = Error

• Message class: CNV_MBT_SHELL - Shell Creation

• Message number: 074

• Message text: Template switch rejected; return to the previous selection

What causes this issue?

Selecting the <ZK>Template</> option results in a new data selection.
The data seen in either <ZK>All Values</> or <ZK>Assigned Values</>
comes directly from table CNVTDMS_13_EXCTB. Selection of a standard
template or package results in CNVTDMS_13_EXCTB data being "mixed" with
information from both tables CNVTDMS_13_TEMPL and CNVTDMS_13_SIZE. There
fore, a different set of data is selected and the current set replaced.
Note that this replacement with calculated template or package data has
no effect on the the contents of table CNVTDMS_13_EXCTB until the save
function is used. However note that this table will be changed as soon
as you save. This means that any manually altered values are
overwritten.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
