How To Fix RSRB1026 - A request param. change also does not result in an approp. precalculation

RSRB1026 - Overview

• Message type: E = Error

• Message class: RSRB1 -

• Message number: 026

• Message text: A request param. change also does not result in an approp. precalculation

What causes this issue?

First the Reporting Agent tries to find a precalculation that exactly
corresponds to the parameterization that resulted from the request URL.
However it could be that there is no precalculation available for it.

System Response

In this case, the system tries to find other precalculations that
contain the request defined by the URL. The other available
characteristics that are not in the drilldown are tested for their
suitability. If a fitting selection is found it can be used as an answer
to the user's request.
Since most of the time there is no clear correct selection, the result
can sometimes be different (as described above).

How to fix this error?

Calling the advanced precalculation search can have the following
causes:
- A control query was used for precalculation; the parameters that
resulted were not considered in the calling URL. To obtain a correct URL
call the transaction RSRAPS (Reporting Agent Page Store) and navigate to
a precalculated package to the Index.htm file. Here you will find a
correct URL for the current detail document as a comment.
- There is no precalculation in the logon language for the current user.
- You are asking for a user-specific precalculation but there are only
precalculations that were created for other users; in this case, either
a general precalculation (not user-specific) must be performed or the
current user has to be added to the precalculation.
- An additional parameterization is provided in the calling URL (such as
user-exit variables), that has neither been defined by the control query
nor by the variable screen of the Web template used during
precalculation as the key for the Reporting Agent.
- A user was given authorization later or added to an authorized role
later or something similar - but there is not current calculation for
this user, which means he cannot yet be recognized as being authorized.
- There really is no suitable precalculation.

Procedure for System Administrators

Perform the appropriate, correct calculation.
