Convert dates

Converts the character-type SAP date (YYYYMMDD, e.g., 19900101) to a special date format (YYYY-MM-DD, e.g., 1990-01-01). Target data uses a real date data-type and not the string data-type to store dates.

Converts the SAP date 00000000 to the entered value.

Year 9999

Converts the SAP date 9999XXXX to the entered value.

Invalid values

If an SAP date cannot be converted to a valid date format, the invalid date is converted to the entered value. NULL is supported as a value. When converting the SAP date the two special cases 00000000 and 9999XXXX are checked first.
