Creating POWL

[Former Member]

Hello,

I am trying to create Custom POWL using the following link:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/60f1d5ee-84ab-2c10-ce97-97dfd89bc...

But in this link for implementing the GET_OBJECTS() method exporting parameter is collected in mt_result table ,for which I am not able to find where it is defined so it's gives an error on Checking Syntax.

Please clarify where it is defined.

Any help would be highly appreciated.

Thanks.

It is not defined by the interface.

You have to define it.

go to the attribute tab and there in a new row type MT_RESULT in the column Attribute.

then press the arrow button present after the fifth column (between associate type and description column).

it will open the private section to declare the attribute.

there modify the line to

data MT_RESULT type table of sflight .

thanks

Thanks for the help.

I was able to proceed further. But now I am getting the following runtime error on testing :

The following error text was processed in the system E75 : Call of a method or kernel Method that has not been implemented

The error occurred on the application server ec7server5_E75_00 and in the work process 0 .

The termination type was: RABAX_STATE

The ABAP call stack was:

Method: NAVIGATE of program CL_WDR_CLIENT_APPLICATION=====CP

Method: DO_NAVIGATION of program CL_WDR_WINDOW_PHASE_MODEL=====CP

Before this I was getting 'Type Conflict when calling the Function Module' error so I changed the line of code as :

FROM: CALL FUNCTION 'POWL_ENCODE_SELPARA' EXPORTING I_SELPARA = LT_QUERY_PARAMS I_ESCAPE = '_line IMPORTING E_SELPARA_STRING = LV_INBOX_QUERY.

TO: CALL FUNCTION 'POWL_ENCODE_SELPARA' EXPORTING I_SELPARA = LT_QUERY_PARAMS I_ESCAPE = '\' IMPORTING E_SELPARA_STRING = LV_INBOX_QUERY.

Please help.

Looking forward to your help.

Yes I did add those 7 parameters to the Outbound Plug , still it gives me the same error.

Pls help.

HI,

Can you please tell me exactly where in your code you get error. is it call to the CALL FUNCTION 'POWL_ENCODE_SELPARA'

or after the fire_out plug ?

i suspect the LV_INBOX_QUERY value which is passed to out bound plug, POWL_UI_COMP throw this error.So try to debug, check once again the if you have followed every instruction correctly in the feeder class implementation.

hello,

Vineet is right,

You have to activate all methods of POWL interface and then check.

Please check POWL Wiki,

http://wiki.sdn.sap.com/wiki/display/WDABAP/POWL

Thanks it works now.

hi,

This error is coming up because you have not implemented the method IF_POWL_FEEDER~GET_SEL_CRITERIA.

- You need to put at least a blank implementation of all the methods of IF_POWL_FEEDER to avoid dump.

- Check All transactions for POWL Query maintainenece.

Further to that it is good to debug the application and check whether all the parameters passed through the POWL plug are intact, and POWL is able to read the Query settings based on the parameter you have passed.

Regards

Vineet
