Diagnosis
You tried to create a DataSource with fields that are not included inthe following ABAP types:

• C Character


• D Date (YYYYMMDD)


• F Floating point number (Float) with 8-byte accuracy


• N Character string only with numbers


• P Packed number (Packed)


• T Time (Time: HHMMSS)


• X Byte sequence (hexadecimal)


• I Entire number (4-byte integer with plus/minus sign)


• b 2-byte integer, only for length field before LCHR or LRAW


• s 1-byte integer, entire number <(><<)>= 254


• a Decimal floating point number, 16 digits


• e Decimal floating point number, 34 digits

By using types other than these, serious problems can occur whenconnecting to the BI DataSource, including not being able to use theDataSources.
For example, it is possible that no transfer structure can be generated.

Procedure
For extraction structure fields for a DataSource (or database table withgeneric DataSources), only use DDIC types based on the above-namedtypes.
