Module Pool Error handling

Former Member — Mon, 12 Apr 2010 09:07:04 GMT

Hi friends,

This issue regarding Module Pool Error Handling

How to handle the multiple error on the same screen ,

For example in the below code you could see "Carrid is Invalid" when carrid is entred wrongly

"in the same way i also need " Connid is invalid" When the customer entres the wrong Connid

*Select single * from sflight into e_sflight*

where carrid = e_sflight-carrid AND

connid = e_sflight-connid AND

fldate = e_sflight-fldate.

IF NOT sy-subrc IS INITIAL.

MESSAGE ID 'ZADT' TYPE 'E'

NUMBER '002' WITH 'Carrid is invalid'.

Kindly let me know your feedback\

Thank you

Sandy

This functionality is possible using OOPS ALV. If you are using a table control, you can replace it by an ALV grid. A pop up can be displayed at the end of user entry with all the errors.

Hi,

Include the fields in a FIELD statement, and enclose it in a CHAIN-ENDCHAIN block statment.

Eg. Screen flow logic:

CHAIN.

FIELD: SPFLI-CARRID, SPFLI-CONNID.

MODULE CHECK_FLIGHT.

ENDCHAIN.

When an error is found inside a chain, the screen is re-displayed, and all fields found anywhere in the chain are input-enabled.

All non-chain fields remain disabled.

Hopes this is helpful.

Raj,
