SAP Error Message - Details

• Message type: E = Error

• Message class: DO - Dictionary: Mass activation of domains and data elements

• Message number: 192

• Message text: There is no check on the mask for data type &

What causes this issue?

For the data types CHAR, NUMC, DEC, INT1, INT2 and INT4, values
can be defined for limiting the value set. However, only for the data
types CHAR and NUMC is a check of the entry values on the mask carried
out with the screen processor. For numeric data types no check is
currently made of the entry values on the mask.

System Response

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

How to fix this error?

If you require a value check on the mask, use data types CHAR and NUMC.
If this is not possible because you need fields of type DEC or INTi,
you currently still have to program the value check yourself.
F4 functionality (possible entries) is supported for all data types.
