Hello

Very interesting subject and well done tutorial, but can you add the implementation for actions methods CREATE_ATT and DO_ACTION.

Those one are missing, so even if there is no error at runtime, test are not correct ..

Cheers

Hi Xavier,

Thanks for your feedback .. yup.. missed the implementation part of CREATE_ATT :razz:

I have added the implementation of those methods.

Hi Rama,

Thanks for the methods.

Finally it works !

Thanks for sharing this point.

Just two others information, in my current system I do not have /MSG/H_POL_ID, I used SIBFBORIID instead. Same for /MSG/HRISK, I used SIBFTYPEID.

And in V_NAME view, I created a SAVE action and implement ONACTIONSAVE method with simply   wd_comp_controller->do_save( ). Otherwise there is a dump.

And one more question, if I want to get the list of attach document for an FI document for example, do you know how to build the policy number ?

Regards

Xavier

Hi Xavier,

Find the entries in table SRGBTBREL where the gos documents are saved and you can find out the keys and same can be used to get the instance of GOS for the business object.

Also, SAVE action, logic added :smile:

Hi Rama,

thanks for the methods.

in creation of : View V_ATTACH_FILES, i create an ui element "FileUpload" in property data i cant effect V_ATTACH_FILES.ATTACHMENT_CONTENTS.CONTENT_X

just type V_ATTACH_FILES.ATTACHMENT_CONTENTS.CONTENT is compatible with this property.

cant you help please!!!!

[ramakrishnappa]

Hi Loli,

I think your system is on lower version like NW7.0,

The field CONTENT_X is of type RAWSTRING in structure GOS_S_ATTCONT and it is not supported in WD context by your system version.

I suggest you to create a context attribute NEW_CONTENT_X of type XSTRING in context directly.

So, you need to have extra attribute in context of type XSTRING and when you save contents, move the data of NEW_CONTENT_X to CONTENT_X of structure in DO_SAVE method ( Refer the  step 5A in PART 1 link )

Hope this helps you.

Regards,

Rama

Hi,

   In my system I have none of the GOS structures or elements you use in the instructions. Also the API  CL_GOS_API does not exist .Why would this be the case and what do I do now?
