Hi,

This is an extract of the log.

How to correct the error

Probably the only way to eliminate the error is to correct the program.

-

If the error occures in a non-modified SAP program, you may be able to

find an interim solution in an SAP Note.

If you have access to SAP Notes, carry out a search with the following

keywords:

"ASSERTION_FAILED" " "

"CL_POBJ_LEVEL1================CP" or "CL_POBJ_LEVEL1================CM013"

"QUERY_LEVELS_USING_SEL_OPTIONS"

Thanks Lucas,

Your help is much appreciated, its like am working in the dark...could you believe implementing MSS with no access to the pdc so I have to relay all error to portal consultant and turn around time is sickening. I will motivate for this to be give and get to you asap.

Thanks.

Now I get the picture... you are developing on portal application but have no admin rights?.... This sure is frustrating when tracing errors. Take your time talking with that consultant, I'll cast an eye at this thread from time to time

Cheers, Lukas

Hi,

Have managed to loon at the Netweaver Administrator for MSS errors generated and there was NOTHING related to my errors.

I got an ABAP resource to look at the dump generated via ST22.

His analysis provided the following:

M_SEARCH_USE_SO_IF Instance attribute

Private type ABAP_BOOL

Use new OADP interface for select options.

Any idea what this might mean or how I can get around this.

[siddharthrajora]

where you are getting this error in which application?

did you check the dumps in St22?

search notes on this if is already fixed.

[Lukas_Weigelt]

This can have hundreds of different root causes. Please provide the entire error log from Netweaver Administrator Default trace log and be careful to post all nestings. For example, a null pointer often occurs when something should have been created earlier but wasn't because some end user permission is missing or the like.

If you post the entire error log for this error, we can help.

Cheers, Lukas
