Error "In the context of Data Services an unknown internal server error occurred"

[Former Member]

Dear Experts,

We're facing the error "In the context of Data Services an unknown internal server error occurred" as soon as we save the created tile.

From transaction /n/IWFND/ERROR_LOG log, we see the errors. For error information, refer the attached screenshot "Gateway_Error_Log".

And also, when we click the already created tile, then we get the error message "For technical reasons this page could not be displayed. Contact your system administrator". Refer the attached screenshot "AUDIT_PAGE".

It seems that Gateway Configuration was not done properly?

Any ideas, please?

Thanks & best regards,

Sreenu

Hello Sree,

Error log is pointing to LastChangedTime property getting filled with invalid format.

Debugging would help to find the exact issue here.

Have you set LastChangedTime property to nullable ?

If not please do this also in model and re-generate objects and clear the cache and check again.

/IWFND/CACHE_CLEANUP

/IWBEP/CACHE_CLEANUP

Hi Ashwin,

Thank you for your Hint.

Do you have idea, exactly, where can I set this property LastChangedTime to nullable?

You can do that in your Model only if its not a key property.

There is a check box which you need to check it.

After that re-generate objects and clear the cache and check again.

/IWFND/CACHE_CLEANUP

/IWBEP/CACHE_CLEANUP

However i would suggest to debug once and see what is the format.

Hi Ashwin,

You mean, changes in Gateway Service Builder (in transaction, SEGW)?

I see blank screen without any content. (see attached screenshot).

Any suggestions, please?

Thanks,

You need to open the respective project to which your service is associated. Then you can see the model information there.

Is it a standard service delivered by SAP ?

Hi Aswin,

Yeah, it is a standard service delivered by SAP.

Actually, we don't see this issue after clearing the cache but we're struck with new ABAP error "MESSAGE_TYPE_X". See the error screenshot in attachment.

Any ideas, please?

Thanks & best regards,

I see dump is because of some thing else ( not because of any gateway component  ) which you need to debug and check the reason for it.

Put a break point inside the Source Code Extract and check. This will help to get the exact issue.

Hi:
that same message came up in a FIORI APP and what I had to do was to validate if the livecache is active in the system with the trx /N/SAPAPO/OM13.

to install it consult these notes:

3152106 - "No data" error when using PP Fiori apps for scheduling

2407589 - Manual installation of liveCache for SAP S/4HANA

Hi Rahul,

Thank you for your response.

We have the following SP levels for the components:

SAP_GWFND Release 740 SP14

IW_FNDGC     Release 100 SP05

Section Invalid format (return table): Row Number X, Property Name 'XXXX_XXX_XX', Property Value 'XX' from your link Issues faced with SAP Gateway (GW by SE80 Method) matches to our error log.

Do you have idea, where can i set the LastChangedTime property to nullable?
