Hi,
you have written "custom fields(ZZ***) which are char type and numeric type"
so could you try please choose another date element which has char, and try to active it,
Level | Category | Description |
1 | Not classified | The structure has no enhancement category |
2 | Cannot be enhanced | The structure cannot be enhanced |
3 | Can be enhanced (character-type) | All structure components and their enhancements must be character-type |
4 | Can be enhanced (character-type or numeric-type) | The structure and its enhancement cannot contain deep data types |
5 | Can be enhanced in any way | The structure and its enhancement can contain components with any data type |
number 3, it means you have to define only char type.
if you have a field with P, or Int, , them you will get a syntax error.
Just try to repace it with char.
Regards
Ibrahim
